I found something that works to some extent, but it still doesn't really do what I want. I used:
#manufacturersContent.sideBoxContent form, select, input {
}
This is fine for controlling the font color and size, but what I really want to adjust is the line-height. All the options are just shoved too close together and it makes it harder to read them. I only have the visible box showing one line, reading, "Please select..." or something like that. The other 100+ options are in the pull down menu. I've tried adjusting each of the following and gotten the indicated results:
padding: box gets bigger (padding added inside box) pull down not affected
margin: box moves (margin applied outside box) pull down moves in line with box
height: box gets bigger, but not as big as with padding (height applied to size of box) pull down not affected
line-height: nothing happens
font-size: font gets bigger - pull down gets bigger accordingly
color: changes font-color - both initial selection and throughout pull down
background-color: changes bgcolor in box & pull-down
Is the line-height of the pull down menu built into the zen_draw_pull_down_menu code itself? I did take a look at where this comes from (functions/html_output.php), but I don't think I want to touch anything there without specific instructions from somebody "in the know."
Any other suggestions to increase the line height in the pull down menu?
