1. CSS Resets

网络上关于CSS重置的代码非常多。本段代码是根据Eric Meyer’s reset codes进行改编的,里面包含一点响应式图片和所有核心元素的边界框设置,这样就可以保持页边距和填充可以很好地对齐。

table { border-collapsecollapseborder-spacing0; }
img { border0max-width100%; }
 
p { font-size1.2emline-height1.0emcolor#333; }

 

2.经典的CSS Clearfix

这个clearfix代码已在Web开发者之间广泛流传,这段类选择器要应用到持有浮动元素的容器中,确保后面的内容都不会浮动,但会被下推和清除。

.clearfix:after { content"."displayblockclearbothvisibilityhiddenline-height0height0; }
.clearfix { display: inline-block; }
  
html[xmlns] .clearfix { displayblock; }
* html .clearfix { height1%; }

3.升级版的Clearfix

在表现上,新版本和经典版本不存在什么差异,这些类可以有效地清除所有floats,但它们只兼容现代浏览器和传统的IE 6-8。

.clearfix:before, .container:after { content""display: table; } 
.clearfix:after { clearboth; }
/* IE 6/7 */
.clearfix { zoom: 1; }

 

 

4. Cross-Browser Transparency 

CSS3里的许多属性都与浏览器相兼容,但也有特例,比如opacity,需要对它进行一些更新才可以。附加过滤属性可以兼容任何老版的IE浏览器。

.transparent {
    filter: alpha(opacity=50);/* internet explorer */
    -khtml-opacity: 0.5;     /* khtml, old safari */
    -moz-opacity: 0.5;      /* mozilla, netscape */
    opacity: 0.5;          /* fx, safari, opera */
}

9. 自定义文本选择

一些新的Web浏览器允许你在网页上自定义一些突出显示的颜色,下面代码的默认颜色是浅蓝色,当然,你可以依据个人爱好进行各种颜色设置。下面代码引用了典型的Webkit和Mozilla供应商前缀::selection 。

::selection { background#e2eae2; }

15. 内容垂直集中

相对于内容在水平位置,内容在垂直方向是不好把控的,尤其当考虑到滚动条这些因素时。这段纯CSS代码可以很好的工作。

.container {
    min-height6.5em;
    displaytable-cell;
    vertical-alignmiddle;
}

    background-image: -webkit-linear-gradient(top#83b842#629721);
    background-image: -moz-linear-gradient(top#83b842#629721);

    background-image: -o-linear-gradient(top#83b842#629721);
    background-image: linear-gradient(top#83b842#629721);
}

18. @Font-Face模板

p a:hover, p a:focus, p a:active {
    text-decoration:underline;
}

20. CSS3 斑马线效果

当用户在浏览许多行数据时,很难分清哪一个单元格是属于哪一行的。默认情况下,通过添加斑马线,用户可以给奇偶行更新不同的背景色。
