Roundiv tab customization

Hi,
I'm using roundiv tabs to show users profiles.
The fact is that my site template uses a white colored font.
So titles, field names etc...appear in white on a white background ( see screenshot )
How can i change that ?
Change background image ? Change roundiv font color ?
Thanks for help

Right click and inspect in Chrome or Firefox the rounded div element and it'll tell you the classes/IDs that you can restyle using CSS. CB 2.x the rounded display is done with Bootstrap 3 Panels, which can also be restyled with CSS. Main issue is you've white text on a light background so it's going to look pretty bad unless you go with a black backgrounded for the rounded display.

Thanks Krileon,
What I got is this :

For CSS3 rounded-corners */
.cbtmpldialog {
padding: 5px 16px 3px;
-webkit-border-radius: 16px;
-moz-border-radius: 16px;
border-radius: 16px;
border: 2px solid #ccc;
margin: 1em 0 2em;
position: relative;

background-color: #c6c6c6;
background-color: rgba(198, 198, 198, 0.;
background-image: -webkit-gradient(linear, 0% 0%, 0% 90%, from(rgba(180, 180, 180, 0.), to(rgba(255, 255, 255, .9)));
background-image: -moz-linear-gradient(rgba(180, 180, 180, 0. 0%, rgba(255, 255, 255, .9) 90%);
border-top-color: #ccc;
border-right-color: #aaa;
border-bottom-color: #bbb;
border-left-color: #aaa;

-webkit-box-shadow: rgba(170, 170, 170, 0.5) 0px 10px 16px;
-moz-box-shadow: rgba(170, 170, 170, 0.5) 0px 10px 16px;

I'm not a "pro" so is it the right place to change background color ( or colors...) ?
Thanks for help

It's using a background color and gradient. Yes, you can add CSS for that selector to restyle it however you need, but you'll need to generate a new gradient, which you can do with the below.
