CSS Browser Hacks

Here we’re going to have a look at a few CSS browser hacks which you can use in those horrible situations where the page looks perfect in all browsers apart for one (IE6 cough!).


@import is used to link an external stylesheet from within a stylesheet/CSS. Earlier version 4 browsers (e.g. Netscape Navigator 4) do not understand this rule and therefore ignore it.

Use the @import if you need to hide styles from older version 4 browsers:

@import "mystyle.css";      /* hidden from most version 4 browsers  */
@import url('mystyle.css'); /* understood by IE4 but not NN4 */

<!–[if IE]> Conditional Statements

Internet Explorer (aka IE) have conditional statements that allow you to give instructions based on the IE and the version of Internet Explorer running.

<!--[if IE]>
This will echo if the browser is Internet Explorer
<!--[if IE 5.5]>
This will echo if the browser is Internet Explorer version 5.5
<!--[if IE 6]>
This will echo if the browser is Internet Explorer version 6

IE 6 Only Hack

If everything works in Firefox, IE7 but not in Internet Explorer 6, use the star html hack:

* html .myclass{
 /* this will only work in IE6	*/

You can also use the underscore hack but I prefer not to as this will cause validation errors in your CSS. Just for reference, here’s an example of the underscore hack:

 _margin-left:5px; /* only IE6 will process this line */

Firefox Only Hack

I came up with this when messing around with child selectors. I don’t know whether it has a name or if other people are using it but it seems to work quite nicely in the version of firefox I was running… (I haven’t tried it in other browsers but  it validates fine)

Update: its called the child hack. Opera and Safari should process this aswell.


p > .myStyle{
color:blue; /* Only Firefox runs this style */

Everything but IE6

Heres a hack that works in Firefox and IE7. Handy if you want everything but IE6 to run it. Better still, it validates as well.

html[xmlns] .myStyle{
 /* Firefox and IE7 process this but the document must be XHTML to work */

To Hack or not to Hack?…

A lot of the time CSS hacks are just a quick solution for us developers, we don’t care how it works as long as it does. However, my advice is avoid this and try to find out why there is a problem in the first place.

A little time spent looking into the problem itself and not a workaround will not only give you a far better understanding of CSS and browser iregularities but also stop you repeating the same thing the next time round.
