CSS页面布局

• 实现三栏布局，中间自适应（margin负值法）

  middle
  left
  right

  body { margin: 0; padding: 0; }

  .left, .right { height: 300px; width: 200px; float: left; }

  .right { margin-left: -200px; background-color: red; }

  .left { margin-left: -100%; background-color: #00ff00; }

  .middle { height: 300px; width: 100%; float: left; background-color: blue; }

• 首尾高度固定、中间自适应的DIV布局（兼容IE6）

  .top, .bottom { width: 100%; height: 50px; position: absolute; }

  /** { margin: 0; padding: 0; }

  html, body, .container { height: 100%; width: 100%; }

  div { position: absolute; }

  .top, .bottom { width: 100%; height: 100px; z-index: 5; }*/

  .top { background: red; top: 0; }

  .bottom { background: #00ff00; bottom: 0; }

  .middle { width: 100%; top: 50px; bottom: 50px; background: #a7fad7; overflow: auto; position: absolute; /针对ie6设定的hack/ _height: 100%; _border-top: -100px solid #eee; _border-bottom: -100px solid #eee; _top: 0; }

  Main Content

  I'm first in the source order.

  The key to victory is discipline, and that means a well made bed. You will practice until you can make your bed in your sleep. Fry, we have a crate to deliver. Hey, guess what you're accessories to.

  I'll get my kit! That's not soon enough! Oh, all right, I am. But if anything happens to me, tell them I died robbing some old man.

  I am a rather effortless column of equal height.

  body { padding: 2em; }

  • { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; }

  h1, h2 { font: bold 2em Sans-serif; margin: 0 0 1em 0; }

  h2 { font-size: 1.5em; }

  p { margin: 0 0 1em 0; }

  .page-wrap { display: flex; display: -webkit-flex; display: -webkit-box; display: -moz-box; display: -ms-flexbox; }

  .main-content, .main-sidebar, .main-nav { padding: 1em; }

  .main-content { -webkit-box-ordinal-group: 2; -moz-box-ordinal-group: 2; -ms-flex-order: 2; order: 2; width: 60%; -moz-box-flex: 1; background: white; }

  .main-nav { -webkit-box-ordinal-group: 1; -moz-box-ordinal-group: 1; -ms-flex-order: 1; order: 1; -webkit-box-flex: 1; -moz-box-flex: 1; width: 20%; -webkit-flex: 1; -ms-flex: 1; flex: 1; background: #ccc; }
