In an earlier post I described how to use conditional comment codes to call a different stylesheet for each browser like so:
<link href=”style.css” rel=”stylesheet” type=”text/css” />
<![if !IE]>
<link href=”not-ie.css” rel=”stylesheet” type=”text/css” />
<![endif]>
At the end of the post I mentioned that you can use these comments to hide other content from each browser. I received some questions on this so I thought I better explain further.
To hide content from IE or a certain version of Internet Explorer is simple just use the appropriate comment codes anywhere on the page with the content between them like so:
The above examples will hide the content from IE or the IE version you specified in teh codes – HOWEVER it will only work that way in IE, because conditional comment codes are not read by Firefox.
So to hide content from Firefox you need to use your Firefox only stylesheet you declared in the header of your file. Whatever it is you want to hide in Firefox just wrap in a <div> with a class or id that in your Firefox stylesheet you add the css property of display: none.
So here is an example:
<div id=”hidemefromfirefox”>
CONTENT TO HIDE FROM FIREFOX
</div>
Then in your Firefox only stylesheet you declare:
#hidemefromfirefox {
display:none;
}
Comments Off on Use conditional comment to hide content from Firefox or Internet Explorer
A handy trick I have been using since IE 7 came out and all of sudden my css was being read a tad differently across each of these browsers: IE6, IE7 and Firefox.
Typically I first design a stylesheet for Internet Explorer, then use a conditional statement to add a second stylesheet where I only include those css items that need to be modified for non-IE browsers – namely Firefox, then I place the two stylesheet calls in the <head> like this:
<link href=”style.css” rel=”stylesheet” type=”text/css” />
<![if !IE]>
<link href=”not-ie.css” rel=”stylesheet” type=”text/css” />
<![endif]>
I list them in that order because only IE reads these codes so in IE it only reads the “style.css”, but in Firefox it reads the “style.css” first then writes over what ever styles are renamed in “non-ie.css”
Here are other conditional comments you can use and what they stand for if you need to get more exact on which browser you are targeting:
<!–[if IE]>
If browser is Internet Explorer<br />
<![endif]–>
<!–[if IE 5]>
If browser is Internet Explorer 5<br />
<![endif]–>
<!–[if IE 5.0]>
If browser is Internet Explorer 5.0<br />
<![endif]–>
<!–[if IE 5.5]>
If browser is Internet Explorer 5.5<br />
<![endif]–>
<!–[if IE 6]>
If browser is Internet Explorer 6<br />
<![endif]–>
<!–[if IE 7]>
If browser is Internet Explorer 7<br />
<![endif]–>
<!–[if gte IE 5]>
If browser is Internet Explorer 5 and up<br />
<![endif]–>
<!–[if lt IE 6]>
If browser is Internet Explorer lower than 6<br />
<![endif]–>
<!–[if lte IE 5.5]>
If browser is Internet Explorer lower or equal to 5.5<br />
<![endif]–>
<!–[if gt IE 6]>
If browser is Internet Explorer greater than 6<br />
<![endif]–>
<![if (IE 6)|(IE 7)]>
If browser is Internet Explorer 6 OR 7 ( | is the OR operator )
<![endif]–>
<![if (gt IE 5)&(lt IE 7)]>
If browser is Internet Explorer 5, 5.5 OR 7 ( & is an AND operator but with the gte and lt it is used as a BETWEEN method )
<![endif]–>
Conditional comments are preferable to weightier browser detection scripts and are cross-browser friendly, so don’t forget that you can use these conditional comments to also include or exclude whatever code you want – not just stylesheets.
