I want to use an image for the background of a select/dropdown. The following CSS works fine in Firefox and IE, but does not in Chrome:
#main .drop-down-loc
Generally, it's considered a bad practice to style standard form controls because the output looks so different on each browser. See: http://www.456bereastreet.com/lab/styling-form-controls-revisited/select-single/ for some rendered examples.
That being said, I've had some luck making the background color an RGBA value:
Google Chrome still renders a gradient on top of the background image in the color that you pass to rgba(r,g,b,0.1) but choosing a color that compliments your image and making the alpha 0.1 reduces the effect of this.
