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';
}

.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 {
transftranslateZ(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-kk) / (1+kk), 2k / (1 + kk), 2k / (1 + kk), (kk - 1) / (1+kk), 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)

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;

transform-style: preserve-3d;

-o-perspective-origin: bottom;
perspective-origin: bottom;

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>

<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

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;
