css3文本与字体
文本阴影
h1 { text-shadow: 5px 5px 5px red; }word-break换行：
h1:nth-child(1) { word-break: normal; } /*英文：一行放不下时整个单词换行*/ h1:nth-child(2) { word-break: break-all; } /*英文：一行放不下时把单词拆开换行*/ h1:nth-child(3) { word-break: keep-all; } /*英文：与normal类似*/ h1:nth-child(4) { word-break: normal; } /*中文：正常*/ h1:nth-child(5) { word-break: break-all; } /*中文：正常*/ h1:nth-child(6) { word-break: keep-all; } /*中文：标点符号之后换行*/word-wrap换行(中文无效)：
h1:nth-child(1) { word-wrap: normal; } /*英文：不换行*/ h1:nth-child(2) { word-wrap: break-word; } /*英文：换行*/文本溢出时处理：
h1:nth-child(1) { text-overflow: clip; } /*隐藏*/ h1:nth-child(2) { text-overflow: ellipsis; } /*省略号显示*/ h1:nth-child(3) { text-overflow: >>; } /*显示指定字符：只火狐有效*/自定义字体
.ttf最常见字体，RAW格式，不做优化
.otf格式
.woff格式，web最佳格式，压缩版本
.eot格式，IE专用格式
.svg
@font-face { font-family: myfont; src: url(font/myFont.eot); src: url(font/myFont.eot?#iefix) format(embedded-opentype), url(font/myFont.ttf) format(truetype), url(font/myFont.woff) format(woff), url(font/myFont.svg#myFont) format(svg); } h1 { font-family: myfont; }获取特殊字体格式文件的网址：

css3转换
2d旋转transform:rotate(deg)
.pic1 { -webkit-transform: rotate(7deg); -moz-transform: rotate(7deg); -ms-transform: rotate(7deg); -o-transform: rotate(7deg); transform: rotate(7deg); }2d平移transform: translate()
div > img { transform: translateX(200px); } div > img { transform: translateY(200px); } div > img { transform: translate(200px, 100px); }2d缩放transform: scale()
div > img { transform: scaleX(.5); } div > img { transform: scaleY(.5); } div > img { transform: scale(.5, .5); }2d斜切Skew()
div > img { transform: skew(15deg, 15deg); /*当只有一个参数的时候，第二个参数默认为0deg*/ } div > img { transform: skewX(15deg); /*逆时针正，顺时针负*/ } div > img { transform: skewY(15deg); }3D旋转
div > img { transform: rotateZ(45deg); } div > img { transform: rotate3d(1, 1, 1, 45deg); /*正：顺时针；负：逆时针*/ }3D平移
div > img { transform: translateZ(200px); } div > img { transform: translate3d(200px, 200px, 200px); }3D缩放
div > img { transform: scaleZ(.5); } div > img { transform: scale3d(.5, .5, .5); }更改原点位置
div > img { transform: rotate3d(1, 1, 1, 45deg); transform-origin: left top 0; }Matrix_translate
transform: matrix(1, 0, 0, 1, x, y)等同于transform: translate(x, y)
div:nth-child(1) > img { transform: matrix(1, 0, 0, 1, 30, 30); } div:nth-child(2) > img { transform: translate(30px, 30px); }Matrix_ scale
transform: matrix(sx, 0, 0, sy, 0, 0)等同于transform: scale(sx, sy)
div:nth-child(1) > img { transform: matrix(.5, 0, 0, .5, 0, 0); } div:nth-child(2) > img { transform: scale(.5, .5); }Matrix_ skew
transform: matrix(1, tanθy, tanθx, 1, 0, 0)等同于transform: skew(θxdeg, θydeg)
div:nth-child(1) > img { transform: matrix(1, .5774, .5774, 1, 0, 0); } div:nth-child(2) > img { transform: skew(30deg, 30deg); }Matrix_ rotate
transform: matrix(cosθ, sinθ, -sinθ, cosθ, 0, 0)等同于transform: rotate(θdeg)
div:nth-child(1) > img { transform: matrix(.7071, .7071, -0.7071, .7071, 0, 0); } div:nth-child(2) > img { transform: rotate(45deg); }Matrix镜像对称：
matrix((1-k*k) / (1+k*k), 2k / (1 + k*k), 2k / (1 + k*k), (k*k - 1) / (1+k*k), 0, 0)
如果对称轴y=-x，即斜率k=-1，代入公式计算：
matrix((1- -1*-1) / (1+ -1*-1)， 2*-1 / (1 + -1*-1)，2*-1 / (1 + -1*-1)，(-1*-1 - 1) / (1+-1*-1), 0, 0)即得到matrix((1- 1) / (1+ 1)， -2 / (1 +1)，-2 / (1 + 1)，(1 - 1) / (1+1), 0, 0)=matrix(0，-1，-1，0, 0, 0)

div:nth-child(1) > img { transform: matrix3d(.5, 0, 0, 0, 0, .5, 0, 0, 0, 0, .5, 0, 0, 0, 0, 1); } div:nth-child(2) > img { transform: scale3d(.5, .5, .5); }transform-style: preserve-3d;
实现父元素对子元素的3D遮罩效果
Demo：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>transform style</title> <style type="text/css"> body { background: #abcdef; } div { position: relative; width: 760px; height: 760px; margin: auto; -webkit-transform-style: preserve-3d; -moz-transform-style: preserve-3d; -ms-transform-style: preserve-3d; -o-transform-style: preserve-3d; transform-style: preserve-3d; } div > .inner { position: absolute; top: 0; right: 0; bottom: 0; left: 0; width: 100%; height: 100%; margin: auto; transform: rotateY(-45deg); background: url(images/circle_inner.png) no-repeat center center; } div > .middle { position: absolute; top: 0; right: 0; bottom: 0; left: 0; width: 100%; height: 100%; margin: auto; transform: rotateX(-45deg); background: url(images/circle_middle.png) no-repeat center center; } div > .outer { position: absolute; top: 0; right: 0; bottom: 0; left: 0; width: 100%; height: 100%; margin: auto; transform: rotateZ(-45deg); background: url(images/circle_outer.png) no-repeat center center; } div > .imooc { position: absolute; top: 0; right: 0; bottom: 0; left: 0; width: 100%; height: 100%; margin: auto; background: url(images/imooc.png) no-repeat center center; } </style> </head> <body> <div> <div class="inner"></div> <div class="middle"></div> <div class="outer"></div> <div class="imooc"></div> </div> </body> </html>perspective: 500px;透视距离，perspective属性指定了观察者与z=0平面的距离，使具有三维位置变换的元素产生透视效果。z>0的三维元素比正常大，而z<0时则比正常小，大小程度由该属性的值决定
perspective-origin: bottom;透视点的位置，默认情况下，消失点位于元素的中心，但是可以通过设置perspective-origin属性来改变其位置
div { position: relative; width: 760px; height: 760px; margin: auto; -webkit-transform-style: preserve-3d; -moz-transform-style: preserve-3d; -ms-transform-style: preserve-3d; -o-transform-style: preserve-3d; transform-style: preserve-3d; -webkit-perspective: 500px; -moz-perspective: 500px; -ms-perspective: 500px; -o-perspective: 500px; perspective: 500px; -webkit-perspective-origin: bottom; -moz-perspective-origin: bottom; -ms-perspective-origin: bottom; -o-perspective-origin: bottom; perspective-origin: bottom; }元素背面是否可见
backface-visibility: hidden; backface-visibility: visible;css3过渡
transition: transform，如果不指定默认是all
div { width: 800px; height: 800px; margin: auto; transform: rotate(0deg); background: url(images/imooc.png) no-repeat center center, url(images/circle_outer.png) no-repeat center center; -webkit-transition: transform 2s ease-in-out 1s; -moz-transition: transform 2s ease-in-out 1s; -ms-transition: transform 2s ease-in-out 1s; -o-transition: transform 2s ease-in-out 1s; transition: transform 2s ease-in-out 1s; } div:hover { cursor: pointer; transform: rotate(180deg); -webkit-transition: transform 2s ease-in-out 1s; -moz-transition: transform 2s ease-in-out 1s; -ms-transition: transform 2s ease-in-out 1s; -o-transition: transform 2s ease-in-out 1s; transition: transform 2s ease-in-out 1s; }transition-timing-function：
#div1 {transition-timing-function: linear;} /*线性*/ #div2 {transition-timing-function: ease;} /*平滑*/ #div3 {transition-timing-function: ease-in;} /*慢入*/ #div4 {transition-timing-function: ease-out;} /*慢出*/ #div5 {transition-timing-function: ease-in-out;} /*慢入慢出*/简写：属性+动画时间+运动函数+延迟时间
transition: transform 2s ease-in-out 1s;当鼠标经过一个元素的时候，该元素翻转360°并且放大一倍显示
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> <style> div { font-size: 14px; font-weight: bold; line-height: 50px; position: fixed; top: 0; right: 0; bottom: 0; left: 0; width: 200px; height: 50px; margin: auto; cursor: pointer; text-align: center; background: #abcdef; /*此处写代码*/ -webkit-transform:rotate(0deg) scale(1); -webkit-transition:transform 1s; } /*此处写代码*/ div:hover{ -webkit-transform:rotate(360deg) scale(2); -webkit-transition:transform 1s; } </style> </head> <body> <div>www.test.com</div> </html>Css3动画
animation-delay 属性定义动画什么时候开始，单位可以是秒（s）或毫秒（ms），允许负值，-2s使动画马上开始，但会跳过2s进入动画
animation-iteration-count: infinite;无限循环/具体的数值
旋转太极：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> <style type="text/css"> div { position: absolute; top: 0; right: 0; bottom: 0; left: 0; box-sizing: border-box; width: 400px; height: 400px; margin: auto; border: 1px solid red; border-bottom: 200px solid red; border-radius: 50%; transform-origin: 50% 50%; animation-name: rotate; animation-duration: 5s; animation-timing-function: linear; animation:rotate 5s linear infinite; } div::before{ content:" "; width:60px; height:60px; border-radius:50%; position: absolute; top:100px; left:0; background-color: red; border: 70px solid white; } div::after{ content:" "; width:60px; height:60px; border-radius:50%; position: absolute; top:100px; right:0; background-color: white; border: 70px solid red; } @keyframes rotate{ from{transform:rotate(0deg);} to{transform:rotate(360deg);} } </style> </head> <body> <div></div> </body> </html>animation-direction与循环搭配，如果动画被设置为只播放一次，该属性将不起作用：
animation-direction: normal; /*正常*/ animation-direction: reverse; /*反向*/ animation-direction: alternate; /*先正向再反向*/ animation-direction: alternate-reverse; /*先反向再正向*/动画暂停或未播放时的样式
animation-fill-mode: none; /*默认*/ animation-fill-mode: forwards; /*动画结束时的状态*/ animation-fill-mode: backwords; /*动画开始时的状态*/ animation-fill-mode: both; /*动画开始或结束的状态*/animation-play-state: paused; /*动画暂停*/ animation-play-state: running; /*动画正在运行*/鼠标悬停时暂停：
div { cursor: pointer; -webkit-animation-play-state: running; animation-play-state: running; } div:hover { cursor: pointer; -webkit-animation-play-state: paused; animation-play-state: paused; }Animation简写：
Animation:name duration timing-function delay iteration-count direction fill-mode play-state;滚屏网页都有一个提示滚屏箭头动画效果
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>2-9</title> <style type="text/css"> div { font-family: Arial; font-size: 72px; font-weight: bold; position: fixed; right: 0; left: 0; width: 30px; height: 30px; margin: auto; transform: rotate(90deg); cursor:pointer; animation:my_move .5s ease-in-out .5s infinite alternate ; } @keyframes my_move{ from{bottom:200px;} to{bottom:100px;} } </style> </head> <body> <div>></div> </body> </html>定义元素忽明忽暗的闪烁效果
