问题描述
我需要在css中使用属性选择器来改变不同颜色和图像的链接,但它不工作。
我有这个html:
< a href =/ manual.pdf> A PDF文件< / a>
此css:
a {
display:block;
height:25px;
padding-left:25px;
color:#333;
font:bold 15px Tahoma;
text-decoration:none;
}
a [href ='。pdf'] {background:red; }
为什么背景不是红色的?
解决方案
在你的href之后使用$。这将使属性值匹配字符串的结尾。
a [href $ ='。pdf' * css * /}

E [foo] foo属性(CSS 2)
E [foo =bar]其foo属性值与bar完全相等的元素(CSS 2)
E [foo〜 bar]一个E元素,其foo属性值是一个空白分隔值的列表,其中一个正好等于bar(CSS 2)
E [foo ^ =bar] an E元素,其foo属性值正好以字符串bar开头(CSS 3)
E [foo $ =bar]一个E元素,其foo属性值以字符串bar CSS 3)
E [foo * =bar]一个E元素,其foo属性值包含子串bar(CSS 3)
E [foo | =en] an E元素,其foo属性具有以en开头(左侧)的连字符值列表(CSS 2)

I need to use attribute selector in css to change link on different color and image, but it does not work.
I have this html:
<a href="/manual.pdf">A PDF File</a>
And this css:
a {
display: block;
height: 25px;
padding-left: 25px;
color:#333;
font: bold 15px Tahoma;
text-decoration: none;
}
a[href='.pdf'] { background: red; }
Why isn't the background red?
解决方案
Use the $ after your href. This will make the attribute value to match the end of the string.
a[href$='.pdf'] { /*css*/ }
JSFiddle: http://jsfiddle.net/UG9ud/
E[foo] an E element with a "foo" attribute (CSS 2)
E[foo="bar"] an E element whose "foo" attribute value is exactly equal to "bar" (CSS 2)
E[foo~="bar"] an E element whose "foo" attribute value is a list of whitespace-separated values, one of which is exactly equal to "bar" (CSS 2)
E[foo^="bar"] an E element whose "foo" attribute value begins exactly with the string "bar" (CSS 3)
E[foo$="bar"] an E element whose "foo" attribute value ends exactly with the string "bar" (CSS 3)
E[foo*="bar"] an E element whose "foo" attribute value contains the substring "bar" (CSS 3)
E[foo|="en"] an E element whose "foo" attribute has a hyphen-separated list of values beginning (from the left) with "en" (CSS 2)
