/*实现一个响应式的正方形布局,第一反应*/ | |

不过这货兼容性...只能说还行 | |
Viewport units: vw, vh, vmin, vmax ✔ 76.03% ◒ 7.57% | |
IE ✘ 5.5+ ◒ 9+¹ ◒ 10+² Edge ◒ ² Firefox ✘ 2+ ✔ 19+ Chrome ✘ 4+ ◒ 20+² ✔ 26+ Safari ✘ 3.1+ ◒ 6+² ✔ 6.1+ Opera ✘ 9+ ✔ 15+ | |
简单解释:IE 近代浏览器支持,chrome/ff/safari 支持比较好,opera 不支持,Android/ios 主流支持比较好 | |
来个兼容性好的思路。padding-bottom/margin-bottom 两个不错。当然你的 box-sizing:content-box; | |
*/ | |
.container{ | |
width: 100%; | |
padding-bottom: 100%; | |
height:0; | |
} | |
/*里面前两个比较容易理解,height0的意识是,我没高度,内容就不要撑破我了。还有一个隐含的问题就是 max-height 没法用了,响应性受到了限制,margin的方案可以试一下*/ | |
.container{ | |
width:100%; | |
} | |
.container:after{ | |
content:''; | |
display:block; | |
margin-top:100%; | |
} | |
/*这种方案比较好,兼容性也好,可以放心的作为 vw 的替代方案了*/ |
