What is a Container?

In CSS, the term Container refers to an element used to structure the layout of a webpage.

A container wraps, aligns, and groups content.

You can use a container to manage the design and structure of a webpage.

Therefore, containers play a crucial role in keeping a webpage clean and logically organized.

To create a container, the <div> tag is often used, but it's preferable to use meaningful tags.

Examples of meaningful tags include <header>, <main>, <footer>, and so on.

Using meaningful tags allows you to quickly understand the structure of a webpage when looking at the code.

It also helps others easily understand the code.

These meaningful tags are referred to as Semantic Tags.

Copy
<nav class="navbar">
  <div class="container"></div>
</nav>

First, the <nav> tag is used to define a navigation area. Then, the <div> tag with the class container is used to create a container.

In this context, both the <nav> tag and the <div> tag act as containers, but they serve slightly different purposes.

• <nav>: Used to define a navigation area.

• <div>: Used to separate or divide content within it.

We will explore the reasons for using each tag further while styling them in the next guide.
