flexbox布局实践1
1、子元素等分
这种布局常用于底部的导航或者tab等分
1 2 3 4 5 6 | ul{ display:flex;}li{ flex:1;} |
完整代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | <!DOCTYPE html><html><head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <title>test1</title> <style> body{ margin:0 } ul{ display:flex; padding:0; } li{ flex:1; background:red; margin:0; list-style:none; height:20px; } </style></head><body><ul> <li>1</li> <li>2</li> <li>3</li></ul></body></html> |
2、左右固定宽度，中间自适应
这种布局常用于左右各有图标的列表
1 2 3 4 5 6 7 8 9 10 | ul{ display:flex;}li:first-child,li:last-child{ width:50px;}li:nth-child(2){ flex:1;} |
完整代码:

3、顶部贴顶，底部贴底
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | html,body,ul{ height:100%;}ul{ display:flex; flex-direction:column;}li:first-child,li:last-child{ height:50px;}li:nth-child(2){ flex:1;} |
