Note: As of Thesis 1.6, a Custom File Editor is available from within the WordPress admin panel, which allows you to make changes to your custom.css (and custom_functions.php) without the need for an external text editor or FTP program.

Do not use word processors such as Microsoft Word, which may add specialized tags or other code which could wreck your custom.css file. Oh, and never, ever save files for the Web as “Rich Text.”

.custom a, .custom a:visited { color: #090; } /* This makes links green */
.custom a:hover { color: #00f; } /* This makes links blue when you mouse over them */
