linear-gradient() 线性渐变创建背景
linear-gradient(位置，颜色 百分比，颜色 百分比)
第一个值指定渐变方向，可以left从左向右，top从上向下
left top 从左上角到右下角；
另外一种写法是角度，
45deg 表示从左下角开始45度渐变，负值表示从左上角开始渐变
第一个颜色表示开始渐变的第一个颜色，百分比表示渐变在整个div背景中所占的比列，
最后一个颜色如果没有百分比，则表示终止时渐变到这个颜色停止，如果加了百分比，表示到了百分比的位置就不会渐变了，而是纯色，颜色为最后一个颜色。
background: -webkit-linear-gradient(left,orange 20%,darkorchid 40%,blue 45%);
