Javascript, CSS: Get element by style attribute

Question

I\'d like to:

1. Find a style attribute for all elements in the page (for instance: all elements that have color:#333;)
2. Change this attribut

Answer 1

You can't, if you don't add at least a specific CSS class to all this elements you want to track.

Or better, you can with very poor performances by looping on all the elements of the DOM until you find what you're looking for. But please, don't think of doing this
