CSS rule based on content [duplicate]

No. :contains was once proposed but is not in the current Working Draft of CSS3 Selectors.

You would need some JavaScript, for example:

for (var i= document.links.length; i-->0;)
    if (/\bSpecificWord\b/i.test(document.links[i].innerHTML)
        document.links[i].style.color= 'red';

You can match attribute values though. If you use custom data attributes, it might get what you want.

yes there is a :contains selector in CSS3.

li:contains("special"){text-style: italic;}

it is mentioned about 1/2 down this page here

This is something you can also do with jQuery too ...

@bobince help me and I wrote this code:

var x = document.getElementsByTagName('TD');
for (var i= x.length; i-->0;)
    if (x[i].innerHTML=='closed')
        x[i].parentNode.style.background= '#FEE';

If the content of some TD is 'closed' then the background color of the TR will be identified with light red color.
