Absolute element inheriting relative parent div's width
提问by abysslogic
I am trying to position a gradient over an inline / inline-block anchor link, and have that gradient inherit the width of that parent anchor. The problem is that the span either inherits the entire width of the anchor's parent, or just the width of the . I am unable to get the span element to properly inherit the width while maintaining the anchors inline display.
我试图在一个内联/内联块锚链接上放置一个渐变，并让该渐变继承该父锚的宽度。问题是跨度要么继承锚的父级的整个宽度，要么只继承 的宽度。我无法在保持锚点内联显示的同时让 span 元素正确继承宽度。

Can't be done with position: absoluteas far as I can see.
position: absolute就我所见，无法完成。
I'm not sure whether this will serve you, but how about giving the aposition: relativeand the a span
我不确定这是否对你有用，但是如何给予aposition: relative和a span
left: 0px;
right: 0px;
top: 0px;
bottom: 0px;
