Always check the Styles tab in the Template Manager > default MASTER template first to see if you can modify any stylistic settings there first... then for custom CSS get familiar with Firebug or Chrome Developer Tools (my preference)
Inspect HTML and CSS in real-time with Developer Tools:
developers.google.com/chrome-developer-tools/
developer.mozilla.org/en-US/docs/Tools
In Chrome I went to your site... I highlighted "Address" (a module title in the Features position) and right-clicked and went to "Inspect Element"... in the 'Style' tab/pane on the right I see the following CSS coding setting the styling for this element:
.title, .component-content h2 {
color: #303030;
text-shadow: 1px 1px 0 #ffffff;
border-bottom: 1px solid #d1d1d1;
-webkit-box-shadow: 0 1px 0 #ffffff;
-moz-box-shadow: 0 1px 0 #ffffff;
box-shadow: 0 1px 0 #ffffff;
}
.title, .component-content h2 {
font-size: 28px;
line-height: 30px;
font-weight: normal;
letter-spacing: normal;
margin-top: 0;
padding-bottom: 15px;
margin-bottom: 15px;
}
So to make the Text white we would place this in our custom css file:
.title, .component-content h2 {
color: #fff;
}
So... maybe you wanted the link like that... just repeat that process on the link... I'll do "hover" next...
I right clicked on "This email address is being protected from spambots. You need JavaScript enabled to view it." and went to inspect element... in my main 'Elements' tab/pane I see the HTML as:<a href="mailto:bvhaase@frontier.com">bvhaase@frontier.com</a>
so I right click on that code in the Elements pane and go to "Force element state: hover" --- now in the 'Styles' tab/pane I can see this code is set:
a:hover {
color: #303030;
}
//quick note: for Hover code you generally want the "parent" element... so if that was wrapped in an unordered list for example we'd set the <li> tag to Hover
So we could drop that in our custom css file and change the hex value... but it's gonna change that sitewide since it isn't any more specific than an "<a>" tag... so if it were me I'd adjust the code like this:
#rt-feature a:hover {
color: #303030;
}
