昌子同学写了一HTML代码，如下：
很奇怪的是，这张图片在Chrome下没有出来，调了各种调式工具疹断，排除了
display: none;
overflow: hidden;
width: 0px;
height: 0px;
/*包括最不可能的*/
position: absolute;
top: npx;
left: npx;
right: npx;
bottom: npx;
之后，此图片还是不出来，啊！！！这是为什么呢？没有道理的啊！！！！调试工具发现了这东西：
Mathed CSS Rules
这是一个奇怪的东西，从未见过。。。
到stackfellow上找到这么一段文字：
What prevents you from mouse-selecting and copying (Ctrl-C, whatever) the contents of the "Matched CSS Rules" or "Computed Styles" section in the sidebar (am I missing the task you are trying to solve?)
There's a known issue with pasting the copied contents into well-known HTML-aware text editors (the CSS properties inside rules are rendered as a numbered list, which is actually a bug in the respective editors) but otherwise, if you want to manually grab a copy of all your matched CSS rules/computed style for a DOM element, this workflow should work for you.
最后我们是以改class名给处理了....
