我以前一直以为旋转跟翻转一样,今日自己旋转了好久都发觉跟翻转差一点点,纠结了十几分钟才明白,只能怪自己的立体感太差了。
css3中的transform中有旋转,放缩,倾斜,平移的功能,分别对应的属性是:rotate,scale,skew,translate
旋转:(rotate)
<span style="color: #800000;">-webkit-transform:rotate(10deg); -moz-transform:rotate(10deg); transform:rotate(10deg); </span><span style="color: #008000;">/*</span><span style="color: #008000;"> 何问起 hovertree.com </span><span style="color: #008000;">*/</span>
翻转:(scale)
(这个属性是放缩的功能,怎么能翻转的!原来括弧里面(1,1)前者表示X轴,后者表示Y轴,当数字大于1时放大,大于0并小于1时缩小,负数代表翻转)
水平翻转:
<span style="color: #800000;">-webkit-transform:scale(-1,1); -moz-transform:scale(-1,1); transform:scale(-1,1); </span><span style="color: #008000;">/*</span><span style="color: #008000;"> 何问起 hovertree.com </span><span style="color: #008000;">*/</span>
垂直翻转:
<span style="color: #800000;">-webkit-transform:scale(1,-1); -moz-transform:scale(1,-1); transform:scale(1,-1); </span><span style="color: #008000;">/*</span><span style="color: #008000;"> 何问起 hovertree.com </span><span style="color: #008000;">*/</span>
