有没有办法使跨浏览器的CSS3代码DRY? [英] Is there a way to make cross-browser CSS3 code DRY?

问题描述

当我想在CSS3中创建渐变背景时，我必须这样做:

When I want to create a gradient background in CSS3 I have to do this:

background-color: #3584ba;
background-image: -webkit-gradient(linear, left top, left bottom, from(#54a0ce), to(#3584ba)); /* Safari 4+, Chrome */
background-image: -webkit-linear-gradient(top, #54a0ce, #3584ba); /* Safari 5.1+, Chrome 10+ */
background-image:    -moz-linear-gradient(top, #54a0ce, #3584ba);  /* FF3.6 */
background-image:      -o-linear-gradient(top, #54a0ce, #3584ba); /* Opera 11.10+ */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#54a0ce', endColorstr='#3584ba'); /* IE */

这真令人讨厌.是否有更好的解决方案，例如jQuery插件，如果我只使用以下代码，它将使我的代码跨浏览器兼容:

and this is really annoying. Is there a better solution, for example a jQuery plugin, that will make my code cross browser compatible, if I just use:

background-image: -webkit-linear-gradient(top, #54a0ce, #3584ba); /* Safari 5.1+, Chrome 10+ */

例如? 是否有工具可以帮助我更轻松地编写CSS3代码?

for example? Is there a tool to help me write CSS3 code more easy?

推荐答案

有很多用于此目的的工具:

There are many tools for this:

• http://lesscss.org/
• http://leafo.net/lessphp/
• http://sass-lang.com/
• http://compass-style.org/

• http://lesscss.org/
• http://leafo.net/lessphp/
• http://sass-lang.com/
• http://compass-style.org/

这些通常称为CSS预处理器.

These are generally referred to as CSS Preprocessors.

您最终将只能编写一次这样的内容，例如函数定义(通常称为"mixin"):

You would end up writing something like this once, like a function definition (usually called a "mixin"):

.linear-gradient(@start, @end) {
    background-color: @end;
    background-image: -webkit-gradient(linear, left top, left bottom, from(@start), to(@end)); /* Safari 4+, Chrome */
    background-image: -webkit-linear-gradient(top, @start, @end); /* Safari 5.1+, Chrome 10+ */
    background-image:    -moz-linear-gradient(top, @start, @end);  /* FF3.6 */
    background-image:      -o-linear-gradient(top, @start, @end); /* Opera 11.10+ */
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='@start', endColorstr='@end'); /* IE */
}

然后申请:

.my-class {
    .linear-gradient(#54a0ce, #3584ba);
}
.my-other-class {
    .linear-gradient(#ccc, #aaa);
}

强烈推荐.
