How to change main slider gray background?

See for yourself, try in Firefox and Internet Explorer and notice that only shows the orange color menu in Firefox and not in IE.

HELP PLEASE.

Would you mind not screaming at volunteers? It only deters volunteers from assisting you.

Well you’re using the orange as a gradient;

#branding #access, #colophon #access-footer {
 background: #222;
 background: -moz-linear-gradient(#FF4800, #FF4800);
 background: -o-linear-gradient(#FF4800, #FF4800);
 background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#FF4800), to(#FF4800));
 background: -webkit-linear-gradient(#FF4800, #FF4800);
 ...
}

but keeping background: #222; for fallback if gradients aren’t supported by browsers.

Do you see what’s going on here?

What I can do to use the color orange?

I do not understand

Help

@andrew Nevins: thanks a lot for your support in the forum.
@chochonet: yes you need to change the default fallback background color. Also don’t change css directly in style.css. Try to use child theme or Custom CSS box in Theme Option under Appearance tab in your WordPress Dashboard. If you change directly on style.css or any theme file then your changes will be gone when you update your theme.

Best you can add the following css in your “Custom CSS” box:

#branding #access,
#colophon #access-footer {
	background: #ff4800; /* Show a solid color for older browsers */
	background: -moz-linear-gradient(#ff4800, #ff4800);
	background: -o-linear-gradient(#ff4800, #ff4800);
	background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#ff4800), to(#ff4800)); /* older webkit syntax */
	background: -webkit-linear-gradient(#ff4800, #ff4800);

Thank you very much to all, now works correctly.

Bye.

Thanks to all.
