The following rule was in the stylesheet for a Joomla component I use: 

    div.thumbs_div a:hover, a:active, a:focus{
    background-color: transparent !important;
    }

Do you spot the syntax error which caused me no end of grief?

I finally did!

It should have been:

    div.thumbs_div a:hover,     div.thumbs_div a:active,     div.thumbs_div a:focus{
    background-color: transparent !important;
    }
