CSS伪元素应用元素的第一个字符
我在h1标签中有以下内容:(Hello World),所以我添加以下到我的css更改此元素的第一个字符:
I have the following content in my h1 tag: "(Hello World)" so I add the following to my css to change the first character of this element:
h1:first-letter { font-size:63px; color:#510007; font-family:Helvetica; }
但是,我注意到,第一个字母只是字母,所以有任何解决方法应用这种风格的第一个字符?在这种情况下是(。
But, as I noticed, first-letter is only for letters, so is there any workarounds to apply this style to the first char? Which in this case is "(".
从 spec :
标点符号,Unicode中定义的字符 [UNICODE] 在开放应该包括在第一个字母之前或之后的第一个字母(Ps),关闭(Pe),初始(Pi),final(Pf)和其他(Po)标点符号类型
Punctuation (i.e, characters defined in Unicode [UNICODE] in the "open" (Ps), "close" (Pe), "initial" (Pi). "final" (Pf) and "other" (Po) punctuation classes), that precedes or follows the first letter should be included
因此,您的括号和字母H由:first-letter
,因为(
被视为标点符号,而不是字母。
So your bracket and the letter H are selected by :first-letter
, because (
is considered a punctuation symbol, not a letter.
有两种解决方法: p>
There are two workarounds:
-
将开头括号括在
span
标签中:
<!-- To style both (), wrap both in <span> tags -->
<h1><span>(</span>Hello World)</h1>
和目标 h1 span
:
h1 span {
font-size: 63px;
color: #510007;
font-family: Helvetica;
}
从文字中删除括号:
Drop the brackets from your text:
<h1>Hello World</h1>
并使用:before
code>:after 改为(不支持在IE7及更早版本):
and use :before
and/or :after
instead (not supported in IE7 and older):
/* To style both (), use h1:before, h1:after */
h1:before {
font-size: 63px;
color: #510007;
font-family: Helvetica;
}
h1:before { content: '('; }
h1:after { content: ')'; }
