CSS3 Transitions, Transforms和Animation

一、Transitions

1.作用 Transitions作用是：平滑的改变CSS的值

2.属性

transition-property :* //指定过渡的性质，比如transition-property:backgrond 就是指backgound参与这个过渡

transition-duration:*//指定这个过渡的持续时间

transition-delay:* //延迟过渡时间

transition-timing-function:*//指定过渡类型，有ease | linear | ease-in | ease-out | ease-in-out | cubic-bezier

示例：

.trans {
    ...
    -webkit-transition: background-color 0.3s ease;
    -moz-transition: background-color 0.3s ease;
    -o-transition: background-color 0.3s ease;
    transition: background-color 0.3s ease;
}
.trans:hover {
    background-color: #486AAA;
    color: #fff;
}

 

3.transform

.trans_skew { transform: skew(35deg); }
.trans_scale { transform:scale(1, 0.5); }
.trans_rotate { transform:rotate(45deg); }
.trans_translate { transform:translate(10px, 20px); }

4.animations

@-webkit-keyframes resize {
    0% {
        padding: 0;
    }
    50% {
        padding: 0 20px;
        background-color:rgba(190, 206, 235, 0.2);        
    }
    100% {
        padding: 0 100px;
        background-color:rgba(190, 206, 235, 0.9);
    }
}
.anim_box:hover {
    -webkit-animation-name: resize;
    -webkit-animation-duration: 1.5s;
    -webkit-animation-iteration-count: 4;
    -webkit-animation-direction: alternate;
    -webkit-animation-timing-function: ease-in-out;
}
