垂直居中：

.center-vertical {

position: relative;

top: 50%;

transform: translateY(-50%);

}

多層邊框：

div{

/* Borders */

box-shadow: 0 0 0 6px rgba(0,0,0,0.2), 0 0 0 12px rgba(0,0,0,0.2), 0 0 0 18px rgba(0,0,0,0.2), 0 0 0 24px rgba(0,0,0,0.2);

/* Meaningless pretty things */

background: linear-gradient(45deg, powderBlue, ghostwhite);

height: 200px;

line-height: 200px;

font-family: sans-serif;

color: MidnightBlue;

margin: 100px auto;

text-align: center;

width: 400px

} 實(shí)時(shí)編輯css

body { color: blue }

css計(jì)算：

.container{

background-position: calc(100% - 50px) calc(100% - 20px);

}

隨機(jī)字符串：：

function generateRandomAlphaNum(len) {

var rdmString = "";

for (; rdmString.length < len; rdmString += Math.random().toString(36).substr(2));

return rdmString.substr(0, len);

}

|0和~~是很好的一個(gè)例子，使用這兩者可以將浮點(diǎn)轉(zhuǎn)成整型且效率方面要比同類(lèi)的parseInt,Math.round要快。在處理像素及動(dòng)畫(huà)位移等效果的時(shí)候會(huì)很有用

var foo = (12.4 / 4.13) | 0;//結(jié)果為3

var bar = ~~(12.4 / 4.13);//結(jié)果為3

禁止別人以iframe加載頁(yè)面：

if (window.location != window.parent.location) window.parent.location = window.location;

總結(jié)
