将元素从容器中分离出来

Question

我将所有内容都包装在一个固定宽度的容器元素中。

但我有一个 <div> 我想“突破”该容器以跨越页面的整个宽度。

正如您在该示例中看到的那样，我有 <div> 突破，但由于它是绝对定位的，它不会影响页面的流动……这就是我想要的它去做。

我希望它表现得像在页面流中一样，但要扩展整个窗口的宽度。

Answer 1

也许 http://jsfiddle.net/sYv9g/1/ ？

 .wrapper {
    width:300px;
    margin:0 auto;
    background:yellow;
}
.break {
    text-align:center;
    font-weight:bold;
    background:rgba(255,0,0, 0.5);
    margin-left:-100%;
    margin-right:-100%;
}

 <div class="wrapper">
    <h1>Ipsum Dapibus Pellentesque Pharetra</h1>
    <p>Duis mollis, est non commodo luctus, nisi erat porttitor ligula, eget lacinia odio sem nec elit. Etiam porta sem malesuada magna mollis euismod. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Morbi leo risus, porta ac consectetur ac, vestibulum at eros. Sed posuere consectetur est at lobortis.</p>
    <div class="break">This should be full width</div>
    <p>Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor. Maecenas sed diam eget risus varius blandit sit amet non magna. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vivamus sagittis lacus vel augue laoreet rutrum faucibus dolor auctor.</p>
    <div class="break">This should be full width</div>
    <p>Nullam id dolor id nibh ultricies vehicula ut id elit. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas faucibus mollis interdum. Donec id elit non mi porta gravida at eget metus. Donec ullamcorper nulla non metus auctor fringilla.</p>
    <p>Vestibulum id ligula porta felis euismod semper. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur blandit tempus porttitor.</p>
</div>

Answer 2

另一个想法，在现代浏览器中确实将 .breakout 拉伸到浏览器窗口的宽度：

 body, html {
  overflow-x: hidden;
  margin: 0;
  padding: 0;
}

div {
  padding:0.5em;
}

.container {
  width:300px;
  background-color:rgba(255,255,0,0.5);
  margin:auto;
}

.breakout {
  margin:1em -100%; /* old browsers fallback */
  margin:1em calc(50% - 50vw);
  background-color:rgba(255,0,255,0.5)
}

 <div class="container">
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

  <div class="breakout">
    Break out of container
  </div>

Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.
</div>

编辑： 唯一的 Chris Coyier 在 Limited Width Parents 中解释了 Full Width Containers ，这有点相似。
