For the whole Modules section, the file Modules.css
is applied dinamicly. You need it for the common styles. However you can import your own css file in that file to overwrite some styles or create new ones. How?
Just open \Sitefinity\Admin\Themes\Default\Modules.css
. There is 2 import rules at the top:@import url(reset.css);
Import your css file just beneath them, for example @import url(your.css);
Notice, that all imported files must be at the top of the css, not below.
However, there is a possibillity that you cannot overwriete some of the css styles in Modules.css, because they are specified AFTER your import. To overwrite them you need to write more specific selectors. For that reason, my suggestion is not to import an external css file, but write your styles in the end of Modules.css
. Then there is no danger of poor overwriting (if your selectors are as specific as the styles in the files are).
