放大:使用css的过渡效果translate就可以了实现
如果你要同时实现,那就都用animate,样式代码写在一起
用CSS3中的transfrom:scale{x,y}来放大,如下:
<style>
*{margin:0padding:0}
div{border:solid 1px #333width:40pxheight:40px}
div img{width:40pxheight:40pxtransition:all 0.3s}
div img:hover{transfrom:scale{2,2}}//从中心放大两部
</style>
<div><img src="图片地址" alt=""/></div>
扩展资料:注意事项
transfrom是利用线性代数来存放一个控件(或许是图片)的具体信息.(由于可以通过transfrom直接操作控件.所以肯定直接或者间接的存储着点的信息和控件的大小等信息)
1、移动.左移右移或者上移下移:
CGAffineTransformMakeTranslation(X偏移量, Y偏移量)
CGAffineTransformTranslate(在某个transform的基础上-一般为自身, X偏移量, Y偏移量)
2、改变大小(形变):
CGAffineTransformMakeScale(宽缩放的倍数, 高缩放的倍数)
CGAffineTransformScale(在某个transform的基础上-一般为自身, 宽缩放的倍数, 高缩放的倍数)
