If you want to update the 2011 theme in the future, you’ll need to create a child theme. Here’s the codex page for child themes: https://codex.www.ads-software.com/Child_Themes . Optionally, this plugin claims to create a child theme for you: https://www.ads-software.com/extend/plugins/one-click-child-theme/ . I have not used the plugin.
The navigation bar in 2011 uses a CSS3 gradient. Here’s the CSS for access (the navigation bar):
#access {
background: -moz-linear-gradient(#252525, #0A0A0A) repeat scroll 0 0 transparent;
box-shadow: 0 1px 2px rgba(0, 0, 0, 0.4);
clear: both;
display: block;
float: left;
margin: 0 auto 6px;
width: 100%;
}
You need to change the first rule regarding background.
If you don’t care about updating the 2011 theme, edit the 2011 style.css file, scroll to the bottom and add this:
#access {
background: -moz-linear-gradient(#252525, #0A0A0A) repeat scroll 0 0 transparent;
}
The two hex values are the starting color and the ending color. To go from black to white the colors would be: (#000000, #FFFFFF). To go from red to blue: (#FF0000, #0000FF). You can experiment with the colors you want.
If you want a solid color change the rule to look like this:
background: none repeat scroll 0 0 #FF0000;
The hex value in the example is red. Change it to match the color you want.
If you create a child theme (recommended), add the new CSS rule to the style.css file for your child theme.
Note: You can use rgb values as well, if you’re more familiar with rgb. For example, using red: rgb(100%,0,0) or rgb(255,0,0).
