问题描述
我有一个巨大的CSS文件，我想修剪下来只使用CSS规则。
I have a huge CSS file which I want to trim down to only used css rules.
我使用。它为每个未使用的规则添加一个UNUSED标签。现在我想摆脱这些。
I did this by using CSS Usage Add-on for Firebug. It adds an "UNUSED" label to every rule not being used. Now I want to get rid of these.
CSS代码看起来像这样：
The CSS code looks like this:
body {
line-height: 1;
text-align: left;
}
UNUSED.multiple-list {
font-weight: bold;
line-height: 1.4;
list-style: disc;
margin-left: 20px
}
UNUSEDmenu, UNUSEDol, ul {
list-style: none
}
UNUSEDblockquote, UNUSEDq {
quotes: none
}
我试图使用RegExr找到我自己的Regex
I tried to find my own Regex using RegExr online service but I was only able to select the part in between the curly braces.
我的正则表达式为：
\{([^}]+)\}
$ b b
如何修改表达式以选择从UNUSED到结束大括号的任何内容？但是，只有当事情从UNUSED开始？
How can I modify the expression to select anything from "UNUSED" to the closing curly brace? But only if things start with "UNUSED"? All other rules should not be marked.
推荐答案
此正则表达式将匹配任何UNUSED属性： UNUSED。* \ {[^}] * \} | UNUSED。* [}] *
正则表达式的一部分匹配任何包含块的UNUSED属性，正则表达式的第二部分（ | 之后）匹配任何不包含块的UNUSED属性 - 你完全覆盖。
它将匹配类，id，块，单行 - 每个UNUSED属性。
The first part of the regex matches any UNUSED attribute that includes a block, and the second part of the regex (after the |) matches any UNUSED attribute that does not include a block - so you're totally covered.It will match classes, id's, blocks, single lines - every UNUSED attribute.
* 有点复杂，但它更好，更安全。看看它。
* jdlx's regex is a bit more complex but it's better and safer. Take a look at it.
