Div Tag in HTML

In HTML, ‘div’ is a tag that specifies division or section in HTML document. But before going in detail of it, let’s first understand about tags in HTML. The tag in HTML can be imagined as a keyword which basically defines how our browser(web-browser) will interpret, format and display the content. The tags act as a line of difference between our HTML content and non-HTML content, this helps the browser to distinguish both efficiently.

HTML tags can be classified into 3 main parts:

  • Opening tag,
  • Content and
  • Closing tag.
Eg:  <tag> content </tag>

Note: There are some tags in HTML which do not require the closing tag, i.e., they are referred to as unclosed tags.

Semantic Tags vs Non-semantic tags in HTML

A semantic tag in HTML is a tag whose name clearly describes its purpose and its content.

Eg:  <h1> —> Used to show important text (generally the heading of the document)

<h6> —> Used to show less important text

<Nav> —>  Used to show navigation information of webpage

<nav>
  <a href="/html/">HTML</a> |
  <a href="/css/">CSS</a> |
  <a href="/js/">JavaScript</a> |




</nav>

Non-semantic tags in HTML

The non-semantic tags can be referred to as the tags in HTML which tells nothing about their content.

Eg:  <div> –> creates a generic container that groups other elements.

<span> –> creates an inline text fragment.

<div> Tag in HTML

The div tag in HTML is a block level element which is used to create a generic container which is generally not visible and is used to group other elements.

When a div tag is declared, all the tags inside it are assigned as a whole separate block. This means if we declare a paragraph (<p> ‘ ‘ ‘ </p>) tag inside a div tag. The paragraph will have a whole block assigned to it.

Eg:

<!DOCTYPE html>
<html>
  <head>
    <title>HTML div Tag</title>
  </head>




  <body>
    <div id="contentinfo">
      <p>Welcome to our website.</p>
      <p>Checkout our huge collection of technical content</p>
<p> Enjoy! your session</p>




    </div>
  </body>
</html>

Output:

Welcome to our website.
Checkout our huge collection of technical content
Enjoy! your session

Code 1: Example of div tag in HTML

  <body>
      <h3>This text is outside the div tag</h3>
    <div class="contentinfo">

<p>This is second paragraph</p>
<p>This is third paragraph</p>
Eg:
<em> This is em tag </em> <em>em is used to </em>  <em> emphasize text</em>

This is first paragraph
This is second paragraph
This is third paragraph

Styling the content of <div>

The main reason to inherit the feature of div tag which allocates a separate block to each individual entity, is to enjoy the benefit of styling each entity on the webpage according to user choice/theme. This not only helps in scaling but also helps in designing beautiful web pages.
