I'm trying to change color layout. In Mediawiki:Common.css (or Vector.css) I've made some changes that work as expected. Apart from one issue. Using an in-line image or fixed image works as expected:
div.vectorTabs span { background-image: url("data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAABkAQAAAABvV2fNAAAADUlEQVQIHWNoYBgWEACJ5TIB0K9KcAAAAABJRU5ErkJggg=="); }
However, a linear-gradient is repeated all over the tab:
div.vectorTabs span { background-image: linear-gradient( #fff6f6 0%, red 100%); }
What's wrong?
