html結構

 <body>
    <div class="container clearfix">
      <div class="center"></div>
      <div class="left"></div>
      <div class="right"></div>
    </div>
    <div>
      <div>123</div>
      <div>123</div>
      <div>123</div>
    </div>
  </body>

css:

container

把左右兩邊距離空出來

.container {
    padding: 0 200px;
}

center

設定widh為100%，即充滿整個容器

.center {
    width: 100%;
}

浮動

設定left，center，right左浮動。
清除container浮動，保證後面的div正常佈局

.left, .center, .right {
    float: left;
}
.clearfix::after {
    display: block;
    height: 0;
    content: "";
    visibility: hidden;
    clear: both
}
.clearfix {
    *zoom: 1;
}

left

使用margin-left： -100%;

.left {
    position: relative;
    margin-left: -100%;
    left: -200px;
}

right

使用margin-right: -200px；;

.right {
    margin-right: -200px;
}

為什麼不用相對定位來移動

.right {
position: relative;
left: -200px;
}

會在第二行向左移動200px，不能和center同行
