phe*_*nry 5 css pseudo-element
像所有有思想的人一样,我讨厌点击一个链接,发现太晚,导致浏览器瘫痪的PDF或Microsoft Office文件.我以为通过在导致这些文件的链接旁边显示一个小图标,我会让人们的生活变得更轻松.随着IE8最终支持:after伪元素,我认为CSS声明会相当简单:
a.file_pdf:after {
content:url('/images/pdf.png');
text-decoration: none;
padding-left: 5px;
}
在IE8中,这很好用.但是,在Firefox和Chrome中,text-decoration: none忽略了下划线,并且下划线在图标底部没有吸引力.有没有办法通过使用额外的<span>标签来解决这个问题而不"欺骗" ？
我正在以不同的方式,使用属性选择器,背景图像和填充(如xandy也建议):
a[href$=".pdf"] {
padding-right: 21px; /* space for the icon */
background: url(graphics/pdf.png) no-repeat right bottom;
}
这也适用于IE7.
在IE7中,PDF图标将不可见,因为它不了解数据URI:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>PDF</title>
<style type="text/css">
a:link,
a:visited {
color: #317408;
background: #eee;
}
a[href$=".pdf"] {
padding-right: 21px;
background-image: url(data:image/png;base64,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);
