一、css实现左侧宽度固定右侧宽度自适应
1、定位
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>自适应</title> <style> *{ padding: 0; margin: 0; } .left{ background: red; width: 200px; height: 200px; position: absolute;/*定位*/ left: 0; top:0; } .right{ background: blue; height: 200px; margin-left: 210px; } </style> </head> <body> <div class="left"> 定宽 </div> <div class="right"> 自适应 </div> </body> </html>
2、浮动
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>自适应</title> <style> *{ padding: 0; margin: 0; } .left{ background: red; width: 200px; height: 200px; float: left;/*浮动*/ } .right{ background: blue; height: 200px; margin-left: 210px; } </style> </head> <body> <div class="left"> 定宽 </div> <div class="right"> 自适应 </div> </body> </html>
3、margin
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>自适应</title> <style> *{ padding: 0; margin: 0; } .left{ background: red; width: 200px; height: 200px; } .right{ background: blue; height: 200px; margin-top: -200px;/*margin*/ margin-left: 210px; } </style> </head> <body> <div class="left"> 定宽 </div> <div class="right"> 自适应 </div> </body> </html>
二、css3弹性盒模型实现自适应
1、上下高度固定中间高度自适应
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> <style> *{ margin: 0; padding: 0; } body,html{ height: 100%; } #contain{ display: flex; flex-direction: column;/*列 垂直方向*/ height: 100%;/*全屏效果 该元素及其父元素及html、body height:100%*/ } #top{ height: 200px; background: red; } #center { flex: 1; background: blue; } #bottom{ height: 100px; background: green; } </style> </head> <body> <div id="contain"> <div id="top">你好</div> <div id="center">你好</div> <div id="bottom">你也好</div> </div> </body> </html>
2、左侧宽度固定右侧宽度自适应
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> <style> * { margin: 0; padding: 0; } #contain { display: flex; /*父元素设置该属性*/ } #left { width: 100px; height: 200px; background: #fff8a8; margin-right: 10px; } #right { flex: 1; /*所占比例/份数*/ height: 200px; background: #ff9bad; } </style> </head> <body> <div id="contain"> <div id="left"></div> <div id="right"></div> </div> </body> </html>
