I'm 80 percent sure that the boxes around each widget have faded in the sidebar. They used to be more visible but now you can hardly see a box or "border" around each widget box.

I'm wondering what setting I have to change it order to make the border darker and more visible.

I'm guessing it's in the Widget Container section.

This is the code that is currently in that section:

font-size: 12px;
margin: 0 0 10px 0;
padding: 10px;
border: solid 4px #eee;
/* uncomment next block for round corners */
/*
-moz-border-radius:5px;
-khtml-border-radius: 5px;
-webkit-border-radius:5px;
border-radius: 5px;
*/

Thanks for your help.

What do you mean they used to be more visible? They wouldn't have changed on their own. Without seeing your site it's hard to tell what you should change but based on the code you sent changing the #eee to something darker would be my guess.

I know they haven't changed on their own, but they definitely were more visible before and somehow I changed it accidently.

Thanks for your help, that code was the thing I needed to change. Now I can find a good colour that matches the website and makes the widgets more visible.

I use the Firefox extension ColorZilla. There are other color pickers that work outside of Firefox that will give you the hex code you need too.

Thanks, I've worked out the same colour that was originally used, now everything is back to normal.
