How to css this little button next to <select> element?

Question

i wanna to change style (background, etc) of the little button with arrow that is on left side of < select > tag. Anyone know if it is possible and how to do that?

Solution

I'm not aware of any good cross-browser methods to style a select box with just css, but I have had success in the past with this using jquery ui
