Is it possible to make changes to a CSS rule-set dynamically (i.e. some JS which would change a CSS rule-set when the user clicks a widget)
This particular CSS rule-set is applied to lots of elements (via a class selector) on the page and I want to modify it when the user clicks the widget, so that all the elements having the class change.
You can, but it’s rather cumbersome. The best reference on how to do it is the following article: Totally Pwn CSS with Javascript (web archive link).
I managed to get it to work with Firefox and IE –
I couldn’t in Chrome, though it appears that it supports the DOM methods.ricosrealm reports that it works in Chrome, too.
