No sweat, glad to help.
Look in:
/common_files/customer/service_css.tpl - or your custom skin directory instead of common_files.
Look a how it calls in the altskin near the bottom:
PHP Code:
{if $AltSkinDir}
{load_defer file="css/altskin.css" type="css"}
If you call another style sheet
after this, with the same classes defined, then the styles from main.css and altskin.css
should be overwritten. I say "should be" because I have never tried it.
