Change color the background the footer

You have an extra space in your hex code; should be this:

#0a2750;

The hexadecimal color code is fine in the style.css file code (# 0a2750) with no spaces. In the help request (above) I accidentally hit it with the space.
Thank you for your retail comment.
I am currently inspecting the code (with F12 from the browser) and still can not change the color of the footer. I can modify it from the inspector, but when it reflects the same code (in the .css file) is not displayed on the web, it is the color before the footer (# 373737). Any other help you can give me?
From already thank you very much.

Fantastic!!! I can resolved the inconvenient. Go the panel ‘Layout Options’ and say where ‘Additional style’, add the follow code:
.footer-bg {display: block;
clear: both;
background-color: #0a2750;}
.site-footer .sidebar-container {background-color: #0a2750;
padding: 20px 0;
clear: both;}

Great!!! I wish this code can serve somebody else, regards !!!
