方法一:用flex布局
1 <!DOCTYPE html> 2 <html> 3 4 <head> 5 <meta charset="{CHARSET}"> 6 <title></title> 7 </head> 8 <style> 9 .parent { 10 height: 500px; 11 border: 1px solid #222; 13 display: flex; 14 } 15 16 .left { 17 width: 200px; 18 border: 1px solid #ccc; 19 margin: 20px; 20 } 21 22 .right { 23 border: 1px solid #ff4400; 24 margin: 20px; 25 flex: 1; 26 } 27 </style> 28 29 <body> 30 <div class="parent"> 31 <div class="left">stable 固定宽度200px</div> 32 <div class="right">changeable 可变宽度</div> 33 </div> 34 </body> 35 36 </html>
方法二:用浮动布局
1 <!DOCTYPE html> 2 <html> 3 4 <head> 5 <meta charset="{CHARSET}"> 6 <title></title> 7 </head> 8 <style> 9 .parent { 10 height: 500px; 11 border: 1px solid #222; 12 } 13 14 .left { 15 float: left; 16 width: 200px; 17 border: 1px solid #ccc; 18 margin: 20px; 19 height: 200px; 20 } 21 22 .right { 23 border: 1px solid #ff4400; 24 margin: 20px; 25 height: 200px; 26 } 27 </style> 28 29 <body> 30 <div class="parent"> 31 <div class="left">stable 固定宽度200px</div> 32 <div class="right">changeable 可变宽度</div> 33 </div> 34 </body> 35 36 </html>
方法三:通过绝对定位
1 <!DOCTYPE html> 2 <html> 3 4 <head> 5 <meta charset="{CHARSET}"> 6 <title></title> 7 </head> 8 <style> 9 .parent { 10 height: 500px; 11 border: 1px solid #222; 12 } 13 14 .left { 15 position: absolute; 16 width: 200px; 17 border: 1px solid #ccc; 18 /*margin: 20px;*/ 19 height: 200px; 20 } 21 22 .right { 23 border: 1px solid #ff4400; 24 margin-left:200px; 25 height: 200px; 26 } 27 </style> 28 29 <body> 30 <div class="parent"> 31 <div class="left">stable 固定宽度200px</div> 32 <div class="right">changeable 可变宽度</div> 33 </div> 34 </body> 35 36 </html>
