提问by MasterDex
I have a header that I want to have a border on that slides from right to left on hover, using pure CSS if that's possible.
我有一个标题，我想在悬停时从右向左滑动的边框上有一个边框，如果可能的话，使用纯 CSS。
At the moment, I can get a border that slides from left to right using the following CSS:
目前，我可以使用以下 CSS 获得一个从左向右滑动的边框：
#header a:after {
content: '';
display: block;
border-bottom: 3px solid $(header.hover.color);
width: 0;
-webkit-transition: 1s ease;
transition: 1s ease;
}
#header a:hover:after { width: 100%; }
Has anyone a good solution for accomplishing this task?
