1. ie的文档流样式 writing-mode:tb-rl
.box1 a{
writing-mode:tb-rl; /* 触发layout 后面高度生效，文档流 自上往下，自右往左，宽度要自适应，文字方向在垂直方向居中 */
height:100%;
vertical-align:middle
}
2. inline-block方式
.box2 i{
zoom:1; height:100%; 0; /* 触发layout，撑起行内的高度，宽度为0，不占横向空间 */
background:#c00;
vertical-align:middle;
}
3. 利用字体大小
.box3{
*display: block;
*font-size: 87px;/约为高度的0.873，200*0.873 约为87/
*font-family:Arial;/防止gbk等编码引起的hack失效问题/
}
4. 绝对定位
