This is the appropriate rule for the 'un-hovered' state:
#primaryContent h1.postTitle a, #primaryContent h2.postTitle a {
background: url("images/title-bg.gif") repeat scroll 0 0 #0097A5;
border-radius: 10px 10px 10px 10px;
color: #FFFFFF;
font-size: 24px;
font-weight: normal;
line-height: 1.5em;
padding: 10px 15px;
text-shadow: -1px -1px #333333;
text-transform: uppercase;
}
In the hover state, a different background image is used.
You've got two choices:
- Replace the background images for both states (with suitable changes to the default background colour
- Remove everything except the background colour from the 'background' rule, to use just a flat colour
Either way, you should ideally make the changes in a Child Theme, by adding a new rule to the (child theme's) style.css file, such as:
#primaryContent h1.postTitle a, #primaryContent h2.postTitle a {
background: url("images/my-new-title-bg.gif") repeat scroll 0 0 #my-new-default-background-colour;
}
(Obviously replacing the 'my-new-' placholders in the above with appropriate values of your own)
