Forum:Track down classes

Hi, I've some questions regarding CSS classes:  [1]
 * 1) Is it possible to track down the page which are using a class in a similar way to how you do with templates? For example, I want to know where a class is used, how do I do that?
 * 2) I've seen on some wikis the use of the class "plainlinks", but I wasn't able to find the class itself in the wiki CSS, anyone knows how should it be declared and what is it its purpose?
 * 3) I think I've already asked this somewhere, but I didn't got a working answer: I want to add some classes to the reference links, basically I want that this
 * become this

 [1]
 * I tried to use this js code (for adding only one class):

function ShowHideReferences { document.getElementByClass('reference').className += 'class1'; } addOnloadHook(ShowHideReferences);
 * but it didn't work, are there any errors? The last point it's not that important, but it will help if you know a solution.


 * Never use  or any variant, as it is a non-standard function. If you're adding a class to every reference link, you may as well just put the styles on  . You can check which elements use what class with an inspector tool, Google Chrome has one by default, Firefox requires an extension such as Firebug. You can't see a list of pages that use a certain class, this is not technically feasible.
