Workflow/ServiceDesk - How To influence HTML elements in a Process View Page

I tested this on 7.5 SP1 with the following code in the 'JScript.js' file:
function showFailed() {
$('div:contains("Ruleset")').each(function() {
$(this).css({"font-weight": "bold", "color": "red"});
});
}
The search text is "Ruleset", you can change this as needed.
The function called is showFailed().
