一、关于浏览器文字选中颜色
以我的系统举例(xp 默认主题),浏览器上页面文字选中后默认的背景色是一种蓝色, 不同浏览器的颜色有些许差异,但大致相同,文字颜色也近乎白色,如下图所示,截自Firefox3.6浏览器:
在CSS3的爸爸妈妈还没有相亲认识的时候,要改变页面上文字选中后的背景色以及文字颜色,就跟让太监生孩子一样困难。但是,随着CSS3呱呱落地,获得越来越多的浏览器认可,一切又显得那么自然而然。虽然有些顽固的糟老头(如IE浏览器)还不认可这个新生的CSS3,但是,丝毫不影响其在其他浏览器上对UI的又一次改进。
目前Firefox、Safari、Chrome以及Opera浏览器都支持文本选择属性,如果浏览器不支持该属性,会直接忽略它,所以不会产生任何不良的影响。
下面就简单展示下这个改进UI体验的小技巧。
二、改变默认选中颜色
首先,简单点的例子,我们可以设置整个页面文本选中的基本样式,如下:
::selection { background:#d3d3d3; color:#555;}::-moz-selection { background:#d3d3d3; color:#555;}::-webkit-selection { background:#d3d3d3; color:#555;}
于是,文本选中的默认蓝色背景就此变成了淡灰色,如下图所示,截自Chrome浏览器:
当然,我们可以使用CSS选择器指定特定标签内容文字选中后的样式状态,例如下面所展示的栗色选中状态:
.maroon::selection { background:maroon; color:#fff;}.maroon::-moz-selection { background:maroon; color:#fff;}.maroon::-webkit-selection { background:maroon; color:#fff;}
会得到类似下图的效果:
同样的,你可以根据自己的需要,指定CSS选择器以及对应内容文字/图片等的选中样式,这里就不一一举例了。
