CSS3 过渡、动画、多列、用户界面

transition过渡

transition: transition-property transition-duration transition-timing-function transition-delay;//过渡名称 过渡时长 过渡时间曲线 过渡延时
.box {
    width: 100px;
    height: 100px;
    line-height: 100px;
    color: red;
    text-align: center;
    background-color: yellow;
    transition: width 2s, height 2s, line-height 2s;
    -webkit-transition: width 2s, height 2s, line-height 2s;
    -moz-transition: width 2s, height 2s, line-height 2s;
    -o-transition: width 2s, height 2s, line-height 2s;
}
.box:hover {
    width: 200px;
    height: 200px;
    line-height: 200px;
}

 

animation 动画

animation: animation-name animation-duration animation-timing-function animation-delay animation-iteration-count animation-direction animation-play-state animation-fill-mode;
/*动画名称 动画周期 动画时间曲线 动画延时 动画次数 动画方向(normal、alternate) 动画暂停或运行(paused、running) 动画在播放之前或之后,其动画效果是否可见(none、forwards、backwards、both)*/
.box {
    position: relative;
    width: 100px;
    height: 100px;
    line-height: 100px;
    text-align: center;
    background-color: green;
    color: yellow;
    -webkit-animation: move  5s linear infinite; 
}
@-webkit-keyframes move {
    0% { left: 0; top: 0; }
    25% { left: 200px; top: 0; background-color: orange;}
    50% { left: 200px; top: 200px; background-color: red; }
    75% { left: 0; top: 200px; background-color: lightblue; }
    100% { left: 0; top: 0; }
}

多列

column-count 元素应该被分隔的列数

column-gap 列与列之间的间隔

column-rule 列与列之间的宽度、样式、颜色规则

div {
  -moz-column-count:3;     /* Firefox */
  -moz-column-rule:3px outset #ff0000;
  -moz-column-gap:40px;
  -webkit-column-count:3; /* Safari 和 Chrome */
  -webkit-column-gap:40px;    
  -webkit-column-rule:3px outset #ff0000;
  column-count:3;    
  column-gap:40px;
  column-rule:3px outset #ff0000;
}

用户界面

resize 规定是否可由用户调整元素的尺寸

resize: none|both|horizontal|vertical;

box-sizing 允许您以确切的方式定义适应某个区域的具体内容

box-sizing: content-box|border-box|inherit;

outline-offset 对轮廓进行偏移,并在边框边缘进行绘制

outline-offset: length|inherit;
