Question

我已经创建了一个网页，现在我正在努力做出回应。它是一个非常简单的页面，包含注册表单和一些链接左侧+右侧。

结构非常简单，例如：

flatMap()

我尝试从某些教程添加媒体查询，但它不起作用，我不知道为什么以及如何执行此操作。这是查询

<div id="wrapper"> 
  <div id="main-content">    
     <div class="text-intro">
        .. some text
     </div>  

     <div id="left-sidebar">            
         <div id="navigation">
              .. some links
         </div>  
     </div>

     <div id="content">
         <div id="form"> 
          .. the form on the right side
         </div>
     </div>
</div>

这是上述来源的完整演示：https://jsfiddle.net/q97odta6/

这里有人可以帮忙吗？

Answer 1

尝试检查 head 标记中添加的viewport meta 标记。如果没有在 head 标记

中添加以下内容

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Answer 2

您可以使用 Flexbox 执行此操作：

＆＃13;

* {margin: 0; padding: 0; box-sizing: border-box}

#wrapper {
  width: 1200px;
  max-width: 100%; /* responsiveness */
  margin: 0 auto; /* horizontally centered */
}

section {
  display: flex; /* displays flex-items (children) inline */
}

aside {
  flex: 1; /* takes the remaining width */
  display: flex;
  justify-content: center; /* horizontally centers the content */
  background: lightgreen;
}

article {
  width: 400px; /* fixed width */
  text-align: center;
  background: lightblue;
}

@media (max-width: 600px) {
  section {flex-direction: column} /* stacks flex-items vertically */
  article {width: initial} /* back to default behavior */
}

＆＃13;

<div id="wrapper"> 
  <section> 
    <aside>            
      <nav>
        links
      </nav>
    </aside>    
    <article>
      text
    </article>
    <aside>
      <form> 
        form
      </form>
    </aside>
  </section>
</div>

这里的东西要短得多。这使用弹性盒系统。由于缺乏对视口的完全控制，因此在现代设计中不建议使用向左浮动。

左浮=旧设计

Flexbox =现代设计

body {
  margin: 0px;
  background: #f5f5f5;
  font-family: "Myriad Set Pro", "Helvetica Neue", Helvetica, Arial, sans-serif;
  letter-spacing: .02em;}

.r {position: relative;}

.white {
  background: white;
  border-radius: 5px;
  box-shadow: 0px 2px 5px rgba(0, 0, 0, 0.25);}

.container {
  width: calc(100% - 40px);
  display: flex;
  padding: 20px;
  max-width: 1000px;
  margin: 0px auto;

.box div {
