Hello,
You can perform it using jQuery. Are you familiar with jQuery?
It is a javascript library that enables you to any visual tasks like dragging windows, made any picture rounded, etc.
for example notice following:
$("div > p").css("border","solid #0C0C0C 1px");
this means that change "border" propery of every "p" tag that is nested into a "div" tag, to "solid #0C0C0C 1px".
I put some files in my blog for you. by these you can learn to perform what you wanted and other things.
