CSS sprites背景和选择器 [英] CSS sprites background and selectors

问题描述

感谢您提供任何帮助。我第一次实现精灵，并寻求简化我的代码。下面是我的css和html。

Thank you in advance for any help you can give. I am implementing sprites for the first time and am looking to streamline my code. Below is my css and html.

CSS

div[class^='Rating']
{ 
    background:url('http://10.0.50.19/images/Ratings.png') no-repeat;
    width:68px; 
    height:13px; 
    display:block;
}
.Rating0_5 { background-position: 0px 0px; }
.Rating1_0 { background-position: 0px -13px; }
.Rating1_5 { background-position: 0px -27px; }
.Rating2_0 { background-position: 0px -41px; }
.Rating2_5 { background-position: 0px -55px; }
.Rating3_0 { background-position: 0px -69px; }
.Rating3_5 { background-position: 0px -83px; }
.Rating4_0 { background-position: 0px -98px; }
.Rating4_5 { background-position: 0px -112px; }
.Rating5_0 { background-position: 0px -125px; }

HTML

<div class="Rating0_5"></div>
<div class="Rating1_0"></div>
....

我遇到的问题是背景位置总是设置为 0px 0px ，因为我相信第一种风格是覆盖background-position元素（根据Firebug）。如果我复制 background：url（'http://10.0.50.19/images/Ratings.png'）no-repeat; c> .RatingX_X 样式它工作正常，但我不想重复 background-image 和重复文本，如果我不必。希望这是有道理的。

The issue I am having is the background-position is always being set to 0px 0px as I believe the first style is overriding the background-position elements (according to Firebug). If I copy copy the background:url('http://10.0.50.19/images/Ratings.png') no-repeat; to each of the .RatingX_X styles it works fine but I don't want to repeat the background-image and repeat text if I don't have to. Hopefully this makes sense. Thanks again.

推荐答案

• 最简单和最跨浏览器的方式是添加您的元素上的公共类（< div class =Rating Rating0_5>< / div> ），然后简单更改 div [class ^ ='评分'] 到 .Rating 。

  • The easiest and most cross-browser way would be to add a common class on your elements (<div class="Rating Rating0_5"></div>) and then simply change div[class^='Rating'] to .Rating.

    可能的解决方案是修复 选择器特性 你的代码。
    或者使用 [class ^ ='Rating'] 或者将你的类选择器写成 div.Rating0_5 。

    Your other possible solution is to fix the selector specificity in your code. Either use simply [class^='Rating'] or write your class selectors as div.Rating0_5.
