将CSS应用于动态命名的元素

Question

I wrote a theme for Google+. It injects CSS/Javascript to replace some colors, background images, etc. They recently seem to have renamed a lot (most) of their classes and ID's. If I were to rewrite the code, is there a way to assign CSS (through javascript, presumably, like jquery's .css() function) to page elements with dynamic names?

EDIT: If so, how?

Code: https://github.com/bichiliad/G-Theme

Example: I used this to replace the logo:

$(".aU-Pg-T img:first").attr('src', logoURL);

However, with the new update, the div enclosing the logo is now ".a-fa-bh-T".

You could use jQuery find() and regex patterns to try to find the elements themselves based on their hierarchy, but if the hierarchy changes then that won't work either. And yes, you could use jQuery's css() to apply those styles.
