Should I include container-fluid in the body or main level for a Bootstrap 4 website?

When designing a Bootstrap 4 site, is it better to add container-fluid at the body or main level?

For example:

<html>
<head></head>
<body class= "container-fluid">
<header></header>
<main></main>
<footer></footer>
</body>
</html>

or

<html>
<head></head>
<body>
<header></header>
<main class= "container-fluid"></main>
<footer></footer>
</body>
</html>

What is the common practice in this scenario?

In the second option, would it be typical to have a container for each section, for instance:

<html>
<head></head>
<body>
<header class= "container-fluid"></header>
<main class= "container-fluid"></main>
<footer class= "container-fluid"></footer>
</body>
</html>

Answer №1

Initially: I believe that a container is essentially a sub-section of the body and can appear multiple times on a page. Personally, I don't see much benefit in using specific header, main, and footer blocks. However, in your scenario, I would structure it as follows:

<html>
<head></head>
<body>
<header></header>
<main>
    <div class="container-fluid"></div>
    <div class="container-fluid"></div>
</main>
<footer></footer>
</body>
</html>

Note: Some CSS frameworks come with predefined styles for elements like header, main, and footer. If this is the case, you should review and adjust these styles accordingly.

Secondly: I am not convinced that this approach is ideal. Generally, the <head> element does not contain styling information. Elements such as header, main, and footer function similarly to divs, allowing you to apply classes to them.

Answer №2

In my opinion, W3Schools articulates a very concise definition of this concept:

According to W3Schools, Bootstrap mandates the use of a containing element to encapsulate site contents.

This is crucial for structuring an entire web site document, as highlighted by the classes (container or container-fluid) in the Bootstrap CSS Framework. These classes are essential for maintaining and adjusting the layout of the entire website when implementing Bootstrap.

When utilizing Bootstrap, you have two options for container classes:

  1. The .container class provides a responsive fixed width container
  2. The .container-fluid class offers a full width container that spans the entire viewport
