How does one target IE7 and IE8 with valid CSS

Question

I want to target IE7 and IE8 with W3C-compliant CSS  Sometimes fixing CSS for one version does not fix for the other  How can I achieve this

The actual problem is not IE8  but the hacks that you use for earlier versions of IE   IE8 is pretty close to be standards compliant  so you shouldn t need any hacks at all for it  perhaps only some tweaks  The problem is if you are using some hacks for IE6 and IE7  you will have to make sure that they only apply to those versions and not IE8   I made the web site of our company compatible with IE8 a while ago  The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant

The answer to your question A completely valid way to select all browsers but IE8 and below is using the  root selector  Since IE versions 8 and below do not support  root  selectors containing it are ignored  This means you could do something like this  p  color red    root p  color blue    This is still completely valid CSS  but it does cause IE8 and lower to render different styles  Other tricks Here s a list of all completely valid CSS browser-specific selectors I could find  except for some that seem quite redundant  such as ones that select for just 1 type of ancient browser  1  2            First the hacks that target certain specific browsers            html p                         color red      IE 6-      html p                         color red      IE 7 only     media screen and  -webkit-min-device-pixel-ratio 0        p                            color red                                                   Chrome  Safari 3     p  body -moz-any-link            color red      Firefox 1      -webkit-any html  p             color red      Chrome 12   Safari 5 1 3      -moz-any html  p                color red      Firefox 4              And then the hacks that target all but certain browsers         html gt  body p                   color green      not  IE lt 7    head body p                    color green      not  IE lt 7  Opera lt 9  Safari lt 3    html first-child p             color green      not  IE lt 7  Opera lt 9 5  Safari amp Chrome lt 4  FF lt 3    html gt     body p                color green      not  IE lt 8    body first-of-type p           color green      not  IE lt 9  Opera lt 9  Safari lt 3  FF lt 3 5     not  ie8min   p               color green      not  IE lt 9  Opera lt 9 5  Safari lt 3 2    body not  oldbrowser   p       color green      not  IE lt 9  Opera lt 9 5  Safari lt 3 2     Credits  amp  sources   http   css-tricks com snippets css browser-specific-hacks  https   en wikipedia org wiki CSS hack http   www webdevout net css-hacks MDN   first-child   root   first-of-type   not     any

I did it using Javascript  I add three css classes to the html element   ie lt version gt  lte-ie lt version gt  lt-ie lt version   1 gt    So for IE7  it adds ie7  lte-ie7      lt-ie8        Here is the javascript code    function          function getIEVersion             var ua   window navigator userAgent          var msie   ua indexOf  MSIE             var trident   ua indexOf  Trident              if  msie  gt  0                   IE 10 or older   gt  return version number             return parseInt ua substring msie   5  ua indexOf      msie    10             else if  trident  gt  0                   IE 11  or newer    gt  return version number             var rv   ua indexOf  rv                 return parseInt ua substring rv   3  ua indexOf      rv    10             else               return NaN                        var ieVersion   getIEVersion         if   isNaN ieVersion        if it is IE         var minVersion   6          var maxVersion   13     adjust this appropriately          if  ieVersion  gt   minVersion  amp  amp  ieVersion  lt   maxVersion                var htmlElem   document getElementsByTagName  html   item 0                var addHtmlClass   function  className       define function to add class to  html  element                 htmlElem className          className                              addHtmlClass  ie    ieVersion      add current version             addHtmlClass  lte-ie    ieVersion                if  ieVersion  lt  maxVersion                    for  var i   ieVersion   1  i  lt   maxVersion    i                        addHtmlClass  lte-ie    i                       addHtmlClass  lt-ie    i                                                           Thereafter  you use the  ie lt version gt  css class in your stylesheet as described by potench    Used Mario s detectIE function in Check if user is using IE with jQuery   The benefit of having lte-ie8 and lt-ie8 etc is that it you can target all browser less than or equal to IE9  that is IE7 - IE9

I would recommend looking into conditional comments and making a separate sheet for the IEs you are having problems with     lt  -- if IE 7  gt      lt link rel  stylesheet  type  text css  href  ie7 css    gt    lt   endif -- gt

Explicitly Target IE versions without hacks using HTML and CSS  Use this approach if you don t want hacks in your CSS  Add a browser-unique class to the  lt html gt  element so you can select based on browser later   Example   lt  doctype html gt   lt  -- if IE  gt  lt   endif -- gt   lt  -- if lt IE 7   gt   lt html lang  en  class  ie6  gt      lt   endif -- gt   lt  -- if IE 7   gt      lt html lang  en  class  ie7  gt      lt   endif -- gt   lt  -- if IE 8   gt      lt html lang  en  class  ie8  gt      lt   endif -- gt   lt  -- if IE 9   gt      lt html lang  en  class  ie9  gt      lt   endif -- gt   lt  -- if  gt IE 9    IE   gt  lt  -- gt  lt html lang  en  gt  lt  -- lt   endif -- gt       lt head gt  lt  head gt       lt body gt  lt  body gt   lt  html gt    Then in your CSS you can very strictly access your target browser   Example   ie6 body        border 1px solid red     ie7 body        border 1px solid blue      For more information check out http   html5boilerplate com      Target IE versions with CSS  Hacks     More to your point  here are the hacks that let you target IE versions   Use   9  to target IE8 and below  Use     to target IE7 and below  Use     to target IE6   Example   body    border 1px solid red     standard    border 1px solid blue 9     IE8 and below     border 1px solid orange     IE7 and below     border 1px solid blue     IE6        Update  Target IE10  IE10 does not recognize the conditional statements so you can use this to apply an  ie10  class to the  lt html gt  element   lt  doctype html gt       lt html lang  en  gt       lt  -- if  IE  gt  lt  -- gt  lt script gt if     cc on    false   document documentElement className    ie10    lt  script gt  lt  -- lt   endif -- gt           lt head gt  lt  head gt           lt body gt  lt  body gt   lt  html gt

Well you don t really have to worry about IE7 code not working in IE8 because IE8 has compatibility mode  it can render pages the same as IE7   But if you still want to target different versions of IE  a way that s been done for a while now is to either use conditional comments or begin your css rule with a   to target IE7 and below  Or you could pay attention to user agent on the servers and dish up a different CSS file based on that information
