我可以应用多个背景颜色与CSS3吗？ [英] Can I apply multiple background colors with CSS3?

问题描述

我知道如何使用CSS3指定多个背景图片，并使用不同的选项修改它们的显示方式。

I know how to specify multiple background images using CSS3 and modify how they are displayed using different options.

目前我有一个

Currently I have a <div>, which needs to have a different color for about 30% of the width on the left side:

div#content {background: url("./gray.png") repeat-y, white; background-size: 30%;}

这个指定的颜色，并且没有额外的< div> s？

Instead of loading the image which is totally gray, how can I do this specifying the color, and without additional <div>s?

推荐答案

你不能真正 - 背景颜色适用于完全的元素背景。

You can’t really — background colours apply to the entirely of element backgrounds. Keeps ’em simple.

您可以为背景定义CSS颜色边界的CSS渐变，例如

You could define a CSS gradient with sharp colour boundaries for the background instead, e.g.

background: -webkit-linear-gradient(left, grey, grey 30%, white 30%, white);

但目前只有少数浏览器支持。请参见 http://jsfiddle.net/UES6U/2/

But only a few browsers support that at the moment. See http://jsfiddle.net/UES6U/2/
