Question

CSS IE6 Conditional statement for style sheet not working

Asked by: jay_eire

Hi Guys,
I have an ASPX page which has two conditional statements, i want to display a different stylesheet if an IE6 user is on my page....my statements are

1)for the style sheet:
<!--[if IE 6]>
<link href="IE6.css" rel="stylesheet" type="text/css" />
<![endif]-->

2) for a paragraph of text
    <!--[if IE 6]>
<h1>This is for IE 6 Only</h1>
<![endif]-->

the paragraph conditional statement works fine in IE 6 but my style sheet statement does not, any ideas what im doing wrong? attached is my code.

Thanks
Jay

I want to allow both style sheets, if the user accesses my site using IE6 to use the IE6 stylesheet if they are using any other browser then the page loads the allbrowsers.css

 

by: NerdsOfTechPosted on 2009-07-08 at 14:53:38ID: 24808803

Thats why I questioned your code

the syntax for if is

if (condition){
 statement;
}

You don't need to move it from between the head tags. You just need to move it after the main stylesheet.

You see, declarations in a stylesheet override declarations in a previous stylesheet where there are conflicts. It's the "cascading" part of CSS. And because of that you only need to include the declarations that are different in the IE6 stylesheet instead of having two complete stylesheets.
