Re: Dynamically replacing entire CSS style

I read that page.  It doesn't provide enough context for me to understand it.

I don't want to replace a stylesheet at run time; I want to replace a single style.  Rule?  Is that the right word?  Whatever is between the { and } in a CSS file, I want to change that for an element.  I need to do it dynamically, with a rule read from a database based on run time data.

Stylesheet is a CSS. A set of rules applicable to the page you're dealing with.
This explanation seems really simple

Hope it helps.
