Even with all of the answers here  I was surprised to find that none really solved the problem   If I used 100vh height min-height  the layout broke when the content was longer than a page  If I instead used 100  height min-height  the layout broke when the content was less than the page height   The solution I found  which solved both cases  was to combine the top two answers   html  body   mydiv     height  100     min-height  100vh

Use FlexBox CSS  Flexbox is a perfect fit for this type of problem  While mostly known for laying out content in the horizontal direction  Flexbox actually works just as well for vertical layout problems  All you have to do is wrap the vertical sections in a flex container and choose which ones you want to expand  They   ll automatically take up all the available space in their container

There are a couple of CSS 3 measurement units called   Viewport-Percentage  or Viewport-Relative  Lengths  What are Viewport-Percentage Lengths   From the linked W3 Candidate Recommendation above      The viewport-percentage lengths are relative to the size of the initial containing block  When the height or width of the initial containing block is changed  they are scaled accordingly    These units are vh  viewport height   vw  viewport width   vmin  viewport minimum length  and vmax  viewport maximum length    How can this be used to make a divider fill the height of the browser   For this question  we can make use of vh  1vh is equal to 1  of the viewport s height  That is to say  100vh is equal to the height of the browser window  regardless of where the element is situated in the DOM tree   HTML   lt div gt  lt  div gt    CSS  div       height  100vh      This is literally all that s needed  Here is a JSFiddle example of this in use   What browsers support these new units   This is currently supported on all up-to-date major browsers apart from Opera Mini  Check out Can I use    for further support   How can this be used with multiple columns   In the case of the question at hand  featuring a left and a right divider  here is a JSFiddle example showing a two-column layout involving both vh and vw   How is 100vh different to 100    Take this layout for example    lt body style  height 100   gt       lt div style  height 200px  gt           lt p style  height 100   display block   gt Hello  world  lt  p gt       lt  div gt   lt  body gt    The p tag here is set to 100  height  but because its containing div has 200 pixels height  100  of 200 pixels becomes 200 pixels  not 100  of the body height  Using 100vh instead means that the p tag will be 100  height of the body regardless of the div height  Take a look at this accompanying JSFiddle to easily see the difference

Try to set height 100  in html  amp  body   html   body       height  100       And if you want to 2 div height same use or set the parent element display flex property

User · Answer

100  works differently for width and height   When you specify width  100   it means  take up 100  of the available width from the parent element or width of the window    When you specify height  100   it only means  take up 100  of available height from the parent element   This means if you don t specify a height at a top level element  the height of all the children will be either 0 or height of the parent  and that is why you need to set the topmost element to have a min-height of window height   I always specify the body to have a min-height of 100vh and it makes positioning and calculations easy   body     min-height  100vh

Actually what worked for me best was using the vh property   In my React application I wanted the div to match the page high even when resized  I tried height  100    overflow-y  auto   but none of them worked when setting height  your percent vh  it worked as intended   Note  if you are using padding  round corners  etc   make sure to subtract those values from your vh property percent or it adds extra height and make scroll bars appear  Here s my sample    frame     background-color  rgb 33  2  211     height  96vh    padding  1  3  2  3     border  1px solid rgb 212  248  203     border-radius  10px    display  grid    grid-gap  5px    grid-template-columns  repeat 6  1fr     grid-template-rows  50px 100px minmax 50px  1fr  minmax 50px  1fr  minmax 50px  1fr

Even though this solution is done with jQuery I though it may be useful for anyone doing columns to fit the screen size   For columns starting at the top of the page  this solution is the simplest   body html    height 100      div right    height 100      For columns that are not starting at the top of the page  for example  if they are starting below the header     lt script gt         document  ready function              var column height      body   height            column height   column height - 100     100 is the header height         column height   column height    px               column   css  height  column height            lt  script gt    First method applies the body height to it and the columns as well  which means that is starting pixels   height100    The second method gets the height of page shown to the user by getting the height of the body and then subtracts the header size to know how much height is left to display the column

You can use vh in this case which is relative to 1  of the height of the viewport     That means if you want to cover off the height  just simply use 100vh   Look at the image below I draw for you here     Try the snippet I created for you as below    x000D   x000D   left   x000D    height  100vh  x000D    width  50   x000D    background-color  grey  x000D    float  left  x000D    x000D   x000D   right   x000D    height  100vh  x000D    width  50   x000D    background-color  red  x000D    float  right  x000D    x000D   lt div class  left  gt  lt  div gt  x000D   lt div class  right  gt  lt  div gt  x000D   x000D   x000D

You don t mention a few important details like    Is the layout fixed width  Are either or both of the columns fixed width    Here s one possibility    x000D   x000D  body  x000D  div   x000D    margin  0  x000D    border  0 none  x000D    padding  0  x000D    x000D   x000D  html  x000D  body  x000D   wrapper  x000D   left  x000D   right   x000D    height  100   x000D    min-height  100   x000D    x000D   x000D   wrapper   x000D    margin  0 auto  x000D    overflow  hidden  x000D    width  960px     width optional x000D    x000D   x000D   left   x000D    background  yellow  x000D    float  left  x000D    width  360px     width optional but recommended  x000D    x000D   x000D   right   x000D    background  grey  x000D    margin-left  360px     must agree with previous width  x000D    x000D   lt html gt  x000D   lt head gt  x000D     lt title gt Example lt  title gt  x000D   lt  head gt  x000D   x000D   lt body gt  x000D     lt div id  wrapper  gt  x000D       lt div id  left  gt  x000D        Left x000D       lt  div gt  x000D   x000D       lt div id  right  gt  lt  div gt  x000D     lt  div gt  x000D   lt  body gt  x000D   x000D   lt  html gt  x000D   x000D   x000D    There are many variations on this depending on which columns need to be fixed and which are liquid  You can do this with absolute positioning too but I ve generally found better results  particularly in terms of cross-browser  using floats instead

If you   re able to absolutely position your elements   position  absolute  top  0  bottom  0    would do it

You need to do two things  one is to set the height to 100  which you already did  Second is set the position to absolute  That should do the trick   html  body     height  100     min-height  100     position  absolute      Source
