How to achieve horizontal positioning of three divs in HTML?

<p>I'm creating a sample website with three horizontal partitions. I want the leftmost partition to be 25% wide, the middle partition to be 50% wide, and the right partition to be 25% wide so that the partitions fill 100% of the space horizontally. </p> <pre class="brush:php;toolbar:false;"><html> <title> Website title </title> <div id="the whole thing" style="height:100%; width:100%" > <div id="leftThing" style="position: relative; width:25%; background-color:blue;"> left menu </div> <div id="content" style="position: relative; width:50%; background-color:green;"> random content </div> <div id="rightThing" style="position: relative; width:25%; background-color:yellow;"> right menu </div> </div> </html></pre> <p>https://i.stack.imgur.com/NZDJe.jpg</p> <p>When I execute this code, the divs appear overlapping. I want them to appear side by side! </p> <p>What should I do? </p>

    I know this is a very old question. I'm posting a solution to this problem here, using FlexBox. Here is the solution: 

    #container {
  height: 100%;
  width: 100%;
  display: flex;
}
#leftThing {
  width: 25%;
  background-color: blue;
}
#content {
  width: 50%;
  background-color: green;
}
#rightThing {
  width: 25%;
  background-color: yellow;
}
    <div id="container">

  <div id="leftThing">
    左侧菜单
  </div>

  <div id="content">
    随机内容
  </div>

  <div id="rightThing">
    右侧菜单
  </div>

</div>

    Just add display:flex to the container! No need to use floats.

    I recommend not using floats to handle this situation, I prefer to use inline-block.

    A few more points to consider:

    • Inline styles are bad for maintainability
    • There should be no spaces in the selector name
    • You have ignored some important HTML tags, such as <head> and <body>
    • You did not include doctype

    Here is a better way to format the document: 

    <!DOCTYPE html>
<html>
<head>
<title>网站标题</title>
<style type="text/css">
* {margin: 0; padding: 0;}
#container {height: 100%; width:100%; font-size: 0;}
#left, #middle, #right {display: inline-block; *display: inline; zoom: 1; vertical-align: top; font-size: 12px;}
#left {width: 25%; background: blue;}
#middle {width: 50%; background: green;}
#right {width: 25%; background: yellow;}
</style>
</head>
<body>
<div id="container">
    <div id="left">左侧菜单</div>
    <div id="middle">随机内容</div>
    <div id="right">右侧菜单</div>
</div>
</body>
</html>

    There is also a jsFiddle for reference.
