CSS Customization
And then comes the time when you urgently need to move that block only a few pixels down to acheive that perfect layout. To satisfy your need for that exquisite look you desire. When links must have a background color. When the existing templates just won't do the job for you.
The solution comes with a custom CSS field that place your code at the end of the so-called cascade, giving you the ability to change most of the styles in the sheet without fear of destroying the default set of style rules. Just use your browser's developer tools and hack away! It's going to be beautiful!
