How to contain one div inside another

In some situations, we have to place one or more Div inside another Div.

<div>
  <div>
    <h2>First Div</h2>
  </div>
  <div>
    <h2>Second Div</h2>
  </div>
</div>

Positioning a div inside another div

output

First Div

Second Div

In the above output, you can see the Div place up and down because CSS Div is a block element that forces a line break before and after the element. In some situation you have to place these Div side by side.

CSS Div side by side

CSS float property enables you to take an element out of normal flow and put content side-by-side. The following example shows how place Div side by side in an HTML page.

<div>
  <div style="float:left">
    <h2>First Div </h2>
  </div>
  <div style="float:left">
    <h2> Second Div</h2>
  </div>
</div>

output

First Div

Second Div

In the above output you can see the Divs are placed side by side. Here second Div placed next to the first Div because we set the second Div float:left;. Float property accepts keyword values left and right float elements those directions respectively and set to none for not floated. If you want to place these Divs left side and right side of your screen, you should specify second Div float:right;

CSS float

<div>
  <div style="float:left">
    <h2>First Div </h2>
  </div>
  <div style="float:right">
    <h2> Second Div</h2>
  </div>
</div>

output

First Div
