Question

CSS让我头痛不已。我的页面有这种格式，并希望将内容添加到中心。我有内容移动或浮动的问题，具体取决于屏幕大小，它在我的屏幕上看起来很棒，但对于有宽屏幕的人来说这看起来不同。任何建议和协助将不胜感激。

#navcontainer { 
  width: 150px;
  height: 500px;
  margin-top:auto;
}           
 #navcontainer ul {

  padding-left: 0;
  list-style-type: none;
  font-family: Arial, Helvetica, sans-serif;

Answer 1

使用媒体查询定位不同的屏幕尺寸。见http://net.tutsplus.com/tutorials/html-css-techniques/quick-tip-a-crash-course-in-css-media-queries/

Answer 2

您是在谈论以屏幕为中心的整个页面的固定宽度吗？

<强> CSS

.wrapper {
  border: 1px solid #ccc;
  margin: 0 auto;
  width: 960px;  
}

.sidecol {
  background: #ccc;
  margin-right: 2%;
  width: 18%;
}

.main-content {
  background: #efefef;
  width: 80%;
}

.sidecol, .main-content {
  float: left;
  height: 400px;
}

<强> HTML

<div class="wrapper">
  <aside class="sidecol">
    <h3>My sidebar</h3>
  </aside>
  <section class="main-content">
    <h3>Content</h3>
    <p> My content</p>
  </section>
</div>

CSS内容浮动在不同大小的屏幕上。
