What methods of clearfix can I use

Question

I have the age-old problem of a div wrapping a two-column layout  My sidebar is floated  so my container div fails to wrap the content and sidebar    lt div id  container  gt     lt div id  content  gt  lt  div gt     lt div id  sidebar  gt  lt  div gt   lt  div gt    There seem to be numerous methods of fixing the clear bug in Firefox     lt br clear  all   gt  overflow auto overflow hidden   In my situation  the only one that seems to work correctly is the  lt br clear  all   gt  solution  which is a little bit scruffy  overflow auto gives me nasty scrollbars  and overflow hidden must surely have side effects  Also  IE7 apparently shouldn t suffer from this problem due to its incorrect behaviour  but in my situation it s suffering the same as Firefox   Which method currently available to us is the most robust

Using overflow hidden auto and height for ie6 will suffice if the floating container has a parent element    Either one of the  test could work  for the HTML stated below to clear floats    test     overflow hidden     or auto     height 1   forces hasLayout in IE6     lt div id  test  gt     lt div style  floatLeft  gt  lt  div gt     lt div style  random  gt  lt  div gt   lt  div gt    In cases when this refuses to work with ie6  just float the parent to clear float     test     float  left     using float to clear float   width  99       Never really needed any other kind of clearing yet  Maybe it s the way I write my HTML

The new standard  as used by Inuit css and Bourbon - two very widely used and well-maintained CSS Sass frameworks    btcf after       content         display block      clear both        Notes  Keep in mind that clearfixes are essentially a hack for what flexbox layouts can now provide in a much smarter way  CSS floats were originally designed for inline content to flow around - like images in a long textual article - and not for grid layouts and the like  If your target browsers support flexbox  it s worth looking into   This doesn t support IE7  You shouldn t be supporting IE7  Doing so continues to expose users to unfixed security exploits and makes life harder for all other web developers  as it reduces the pressure on users and organisations to switch to modern browsers   This clearfix was announced and explained by Thierry Koblentz in July 2012  It sheds unnecessary weight from Nicolas Gallagher s 2011 micro-clearfix  In the process  it frees a pseudo-element for your own use  This has been updated to use display  block rather than display  table  again  credit to Thierry Koblentz

A clearfix is a way for an element to automatically clear after itself   so that you don t need to add additional markup    clearfix after      content          Older browser do not support empty content       visibility  hidden     display  block     height  0     clear  both     cleaner     clear  both      Normally you would need to do something as follows    lt div style  float  left   gt Sidebar lt  div gt   lt div class  cleaner  gt  lt  div gt   lt  -- Clear the float -- gt    With clearfix  you only need to   lt div style  float  left   class  clearfix  gt Sidebar lt  div gt   lt  -- No Clearing div  -- gt

What problems are we trying to solve   There are two important considerations when floating stuff    Containing descendant floats  This means that the element in question makes itself tall enough to wrap all floating descendants   They don t hang outside     Insulating descendants from outside floats  This means that descendants inside of an element should be able to use clear  both and have it not interact with floats outside the element      Block formatting contexts  There s only one way to do both of these  And that is to establish a new block formatting context  Elements that establish a block formatting context are an insulated rectangle in which floats interact with each other  A block formatting context will always be tall enough to visually wrap its floating descendants  and no floats outside of a block formatting context may interact with elements inside  This two-way insulation is exactly what you want  In IE  this same concept is called hasLayout  which can be set via zoom  1   There are several ways to establish a block formatting context  but the solution I recommend is display  inline-block with width  100    Of course  there are the usual caveats with using width  100   so use box-sizing  border-box or put padding  margin  and border on a different element    The most robust solution  Probably the most common application of floats is the two-column layout   Can be extended to three columns    First the markup structure    lt div class  container  gt     lt div class  sidebar  gt      sidebar lt br  gt sidebar lt br  gt sidebar    lt  div gt     lt div class  main  gt       lt div class  main-content  gt        main content        lt span style  clear  both  gt          main content that uses  lt code gt clear  both lt  code gt         lt  span gt       lt  div gt     lt  div gt   lt  div gt    And now the CSS      Should contain all floated and non-floated content  so it needs to    establish a new block formatting context without using overflow  hidden       container     display  inline-block    width  100     zoom  1     new block formatting context via hasLayout for IE 6 7          Fixed-width floated sidebar      sidebar     float  left    width  160px        Needs to make space for the sidebar      main     margin-left  160px        Establishes a new block formatting context to insulate descendants from    the floating sidebar      main-content     display  inline-block    width  100     zoom  1     new block formatting context via hasLayout for IE 6 7        Try it yourself  Go to JS Bin to play around with the code and see how this solution is built from the ground up   Traditional clearfix methods considered harmful  The problem with the traditional clearfix solutions is that they use two different rendering concepts to achieve the same goal for IE and everyone else  In IE they use hasLayout to establish a new block formatting context  but for everyone else they use generated boxes   after  with clear  both  which does not establish a new block formatting context  This means things won t behave the same in all situations  For an explanation of why this is bad  see Everything you Know about Clearfix is Wrong

Given the huge amount of replies I was not gonna post  However  this method may help someone  as it did help me  Stay way from floats whenever possible It s worth to mention  I avoid floats like Ebola  There are many reasons and I am not alone  Read Rikudo answer about what is a clearfix and you ll see what I mean  In his own words     the use of floated elements for layout is getting more and more discouraged with the use of better alternatives    There are other good  and sometimes better  options out there other than floats  As technology advances and improves  flexbox  and other methods  are going to be widely adopted and floats will become just a bad memory  Maybe a CSS4   Float misbehavior and failed clears First off  sometimes  you may think that you are safe from floats until your lifesaver is punctured and your html flow starts to sink  In the codepen http   codepen io omarjuvera pen jEXBya below  the practice of clearing a float with  lt div classs  quot clear quot  gt  lt  div gt   or other element  is common but frown upon and anti-semantic   lt div class  quot floated quot  gt 1st lt  div gt   lt div class  quot floated quot  gt 2nd lt  div gt   lt div class  quot floated quot  gt 3nd lt  div gt   lt div classs  quot clear quot  gt  lt  div gt   lt  -- Acts as a wall -- gt   lt section gt Below lt  section gt   CSS div       border  1px solid  f00      width  200px      height  100px     div floated       float  left      clear       clear  both    section       border  1px solid  f0f     However  just when you thought your float is sail worthy   boom  As the screen size becomes smaller and smaller you see weird behaviors in like the graphic below  Same http   codepen io omarjuvera pen jEXBya    Why should you care  Roughly  about 80   or more  of the devices used are mobile devices with small screens  Desktop computers laptops are no longer king   It does not end there This is not the only problem with floats  There are many  but in this example  some may say all you have to do is to place your floats in a container  But as you can see in the codepen and graphic  that is not the case  It apparently made things worst  HTML  lt div id  quot container quot  class  quot  quot  gt     lt div class  quot floated quot  gt 1st lt  div gt     lt div class  quot floated quot  gt 2nd lt  div gt     lt div class  quot floated quot  gt 3nd lt  div gt   lt  div gt   lt  --   conteiner -- gt   lt div classs  quot clear quot  gt  lt  div gt   lt  -- Acts as a wall -- gt   lt section gt Below lt  section gt   CSS  container     min-height  100px     To prevent it from collapsing      border  1px solid  0f0     floated       float  left      border  1px solid  f00      width  200px      height  100px      clear       clear  both    section       border  1px solid  f0f     As for the result  It s the     same   Least you know  you ll start a CSS party  inviting all kinds of selectors and properties to the party  making a bigger mess of your CSS than what you started with  Just to fix your float   CSS Clearfix to the rescue This simple and very adaptable piece of CSS is a beauty and a  quot savior quot    clearfix before   clearfix after        content   quot  quot       display  table      clear  both      zoom  1     ie 6 7       That s it  It really works without breaking semantics and did I mention it works   From the same sample   HTML  lt div class  quot clearfix quot  gt       lt div class  quot floated quot  gt 1st lt  div gt       lt div class  quot floated quot  gt 2nd lt  div gt       lt div class  quot floated quot  gt 3nd lt  div gt   lt  div gt   lt section gt Below lt  section gt   CSS div floated       float  left      border  1px solid  f00      width  200px      height  100px    section           border  4px solid  00f       clearfix before   clearfix after        content   quot  quot       display  table      clear  both      zoom  1     ie 6 7        Now we no longer need  lt div classs  quot clear quot  gt  lt  div gt   lt  -- Acts as a wall -- gt  and keep the semantic police happy  This is not the only benefit  This clearfix is responsive to any screen size without the use of  media in it s simplest form  In other words  it will keep your float container in check and preventing floodings  Lastly  it provides support for old browsers all in one small karate chop    Here s the clearfix again  clearfix before   clearfix after        content   quot  quot       display  table      clear  both      zoom  1     ie 6 7

Unlike other clearfixes  here is an open-ended one without containers Other clearfixes either require the floated element to be in a well marked off container or need an extra  semantically empty  lt div gt   Conversely  clear separation of content and markup requires a strict CSS solution to this problem  The mere fact that one needs to mark off the end of a float  does not allow for unattended CSS typesetting  If the latter is your goal  the float should be left open for anything  paragraphs  ordered and unordered lists etc   to wrap around it  until a  quot clearfix quot  is encountered  For example  the clearfix might be set by a new heading  This is why I use the following clearfix with new headings  h1       clear  both      display  inline-block      width  100      This solution gets used extensively on my website to solve the problem  The text next to a floated miniature is short and the top-margin of the next clearing object is not respected  It also prevents any manual intervention when automatically generating PDFs from the site  Here is an example page

I d float  content too  that way both columns contain floats  Also because it will allow you to clear elements inside  content without clearing the side bar   Same thing with the wrapper  you d need to make it a block formatting context to wrap the two columns   This article mentions a few triggers you can use  block formatting contexts

It is so simple clearfix clears the issue by when we using the float properties inside the div element If we use two div elements one as float left  and other one as float right  we can use clearfix for the parent of the two div element  If we refuse to use clearfix unnecessary spaces fill with contents below and site structure will be broken

Given the huge amount of replies I was not gonna post  However  this method may help someone  as it did help me  Stay way from floats whenever possible It s worth to mention  I avoid floats like Ebola  There are many reasons and I am not alone  Read Rikudo answer about what is a clearfix and you ll see what I mean  In his own words     the use of floated elements for layout is getting more and more discouraged with the use of better alternatives    There are other good  and sometimes better  options out there other than floats  As technology advances and improves  flexbox  and other methods  are going to be widely adopted and floats will become just a bad memory  Maybe a CSS4   Float misbehavior and failed clears First off  sometimes  you may think that you are safe from floats until your lifesaver is punctured and your html flow starts to sink  In the codepen http   codepen io omarjuvera pen jEXBya below  the practice of clearing a float with  lt div classs  quot clear quot  gt  lt  div gt   or other element  is common but frown upon and anti-semantic   lt div class  quot floated quot  gt 1st lt  div gt   lt div class  quot floated quot  gt 2nd lt  div gt   lt div class  quot floated quot  gt 3nd lt  div gt   lt div classs  quot clear quot  gt  lt  div gt   lt  -- Acts as a wall -- gt   lt section gt Below lt  section gt   CSS div       border  1px solid  f00      width  200px      height  100px     div floated       float  left      clear       clear  both    section       border  1px solid  f0f     However  just when you thought your float is sail worthy   boom  As the screen size becomes smaller and smaller you see weird behaviors in like the graphic below  Same http   codepen io omarjuvera pen jEXBya    Why should you care  Roughly  about 80   or more  of the devices used are mobile devices with small screens  Desktop computers laptops are no longer king   It does not end there This is not the only problem with floats  There are many  but in this example  some may say all you have to do is to place your floats in a container  But as you can see in the codepen and graphic  that is not the case  It apparently made things worst  HTML  lt div id  quot container quot  class  quot  quot  gt     lt div class  quot floated quot  gt 1st lt  div gt     lt div class  quot floated quot  gt 2nd lt  div gt     lt div class  quot floated quot  gt 3nd lt  div gt   lt  div gt   lt  --   conteiner -- gt   lt div classs  quot clear quot  gt  lt  div gt   lt  -- Acts as a wall -- gt   lt section gt Below lt  section gt   CSS  container     min-height  100px     To prevent it from collapsing      border  1px solid  0f0     floated       float  left      border  1px solid  f00      width  200px      height  100px      clear       clear  both    section       border  1px solid  f0f     As for the result  It s the     same   Least you know  you ll start a CSS party  inviting all kinds of selectors and properties to the party  making a bigger mess of your CSS than what you started with  Just to fix your float   CSS Clearfix to the rescue This simple and very adaptable piece of CSS is a beauty and a  quot savior quot    clearfix before   clearfix after        content   quot  quot       display  table      clear  both      zoom  1     ie 6 7       That s it  It really works without breaking semantics and did I mention it works   From the same sample   HTML  lt div class  quot clearfix quot  gt       lt div class  quot floated quot  gt 1st lt  div gt       lt div class  quot floated quot  gt 2nd lt  div gt       lt div class  quot floated quot  gt 3nd lt  div gt   lt  div gt   lt section gt Below lt  section gt   CSS div floated       float  left      border  1px solid  f00      width  200px      height  100px    section           border  4px solid  00f       clearfix before   clearfix after        content   quot  quot       display  table      clear  both      zoom  1     ie 6 7        Now we no longer need  lt div classs  quot clear quot  gt  lt  div gt   lt  -- Acts as a wall -- gt  and keep the semantic police happy  This is not the only benefit  This clearfix is responsive to any screen size without the use of  media in it s simplest form  In other words  it will keep your float container in check and preventing floodings  Lastly  it provides support for old browsers all in one small karate chop    Here s the clearfix again  clearfix before   clearfix after        content   quot  quot       display  table      clear  both      zoom  1     ie 6 7

I d float  content too  that way both columns contain floats  Also because it will allow you to clear elements inside  content without clearing the side bar   Same thing with the wrapper  you d need to make it a block formatting context to wrap the two columns   This article mentions a few triggers you can use  block formatting contexts

Unlike other clearfixes  here is an open-ended one without containers Other clearfixes either require the floated element to be in a well marked off container or need an extra  semantically empty  lt div gt   Conversely  clear separation of content and markup requires a strict CSS solution to this problem  The mere fact that one needs to mark off the end of a float  does not allow for unattended CSS typesetting  If the latter is your goal  the float should be left open for anything  paragraphs  ordered and unordered lists etc   to wrap around it  until a  quot clearfix quot  is encountered  For example  the clearfix might be set by a new heading  This is why I use the following clearfix with new headings  h1       clear  both      display  inline-block      width  100      This solution gets used extensively on my website to solve the problem  The text next to a floated miniature is short and the top-margin of the next clearing object is not respected  It also prevents any manual intervention when automatically generating PDFs from the site  Here is an example page

What problems are we trying to solve   There are two important considerations when floating stuff    Containing descendant floats  This means that the element in question makes itself tall enough to wrap all floating descendants   They don t hang outside     Insulating descendants from outside floats  This means that descendants inside of an element should be able to use clear  both and have it not interact with floats outside the element      Block formatting contexts  There s only one way to do both of these  And that is to establish a new block formatting context  Elements that establish a block formatting context are an insulated rectangle in which floats interact with each other  A block formatting context will always be tall enough to visually wrap its floating descendants  and no floats outside of a block formatting context may interact with elements inside  This two-way insulation is exactly what you want  In IE  this same concept is called hasLayout  which can be set via zoom  1   There are several ways to establish a block formatting context  but the solution I recommend is display  inline-block with width  100    Of course  there are the usual caveats with using width  100   so use box-sizing  border-box or put padding  margin  and border on a different element    The most robust solution  Probably the most common application of floats is the two-column layout   Can be extended to three columns    First the markup structure    lt div class  container  gt     lt div class  sidebar  gt      sidebar lt br  gt sidebar lt br  gt sidebar    lt  div gt     lt div class  main  gt       lt div class  main-content  gt        main content        lt span style  clear  both  gt          main content that uses  lt code gt clear  both lt  code gt         lt  span gt       lt  div gt     lt  div gt   lt  div gt    And now the CSS      Should contain all floated and non-floated content  so it needs to    establish a new block formatting context without using overflow  hidden       container     display  inline-block    width  100     zoom  1     new block formatting context via hasLayout for IE 6 7          Fixed-width floated sidebar      sidebar     float  left    width  160px        Needs to make space for the sidebar      main     margin-left  160px        Establishes a new block formatting context to insulate descendants from    the floating sidebar      main-content     display  inline-block    width  100     zoom  1     new block formatting context via hasLayout for IE 6 7        Try it yourself  Go to JS Bin to play around with the code and see how this solution is built from the ground up   Traditional clearfix methods considered harmful  The problem with the traditional clearfix solutions is that they use two different rendering concepts to achieve the same goal for IE and everyone else  In IE they use hasLayout to establish a new block formatting context  but for everyone else they use generated boxes   after  with clear  both  which does not establish a new block formatting context  This means things won t behave the same in all situations  For an explanation of why this is bad  see Everything you Know about Clearfix is Wrong

The new standard  as used by Inuit css and Bourbon - two very widely used and well-maintained CSS Sass frameworks    btcf after       content         display block      clear both        Notes  Keep in mind that clearfixes are essentially a hack for what flexbox layouts can now provide in a much smarter way  CSS floats were originally designed for inline content to flow around - like images in a long textual article - and not for grid layouts and the like  If your target browsers support flexbox  it s worth looking into   This doesn t support IE7  You shouldn t be supporting IE7  Doing so continues to expose users to unfixed security exploits and makes life harder for all other web developers  as it reduces the pressure on users and organisations to switch to modern browsers   This clearfix was announced and explained by Thierry Koblentz in July 2012  It sheds unnecessary weight from Nicolas Gallagher s 2011 micro-clearfix  In the process  it frees a pseudo-element for your own use  This has been updated to use display  block rather than display  table  again  credit to Thierry Koblentz

It is so simple clearfix clears the issue by when we using the float properties inside the div element If we use two div elements one as float left  and other one as float right  we can use clearfix for the parent of the two div element  If we refuse to use clearfix unnecessary spaces fill with contents below and site structure will be broken

A clearfix is a way for an element to automatically clear after itself   so that you don t need to add additional markup    clearfix after      content          Older browser do not support empty content       visibility  hidden     display  block     height  0     clear  both     cleaner     clear  both      Normally you would need to do something as follows    lt div style  float  left   gt Sidebar lt  div gt   lt div class  cleaner  gt  lt  div gt   lt  -- Clear the float -- gt    With clearfix  you only need to   lt div style  float  left   class  clearfix  gt Sidebar lt  div gt   lt  -- No Clearing div  -- gt
