What is the reasoning behind placing the <nav> Navbar element outside of a container?

Can anyone shed light on why the semantic Navbar <nav> element is located outside the outermost

<div class="container">
?

Referencing the documentation for Bootstrap Navbar here

    <nav class="navbar navbar-default">
        <div class="container-fluid">
        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
            <span class="sr-only">Toggle navigation</span>
            ...
        </div>
        ...
    </nav>

I initially believed that, in order to properly utilize Bootstrap, all elements needed to be within a container > row > col structure.

However, after some experience, I've come to realize that there are exceptions and things aren't always straightforward. Therefore, I'm delving into my app's front-end to gain a deeper understanding of the processes involved.

Could it be that the answer lies in the fact that the <nav> element serves a special purpose and therefore resides outside traditional containers, especially when used for site-wide navigation?

My research journey so far:

  1. Browsed through 10+ "Similar questions"
  2. Explored getbootstrap.com extensively
  3. Consulted w3schools
  4. Conducted a Google search on "<nav>"

Answer №1

It was my understanding that Bootstrap needed everything to be structured in a container > row > col for the grid system to function properly. However, typically navigation components are not part of the grid system initially; usually, you have a separate navigation and then the main content of the page which might utilize the grid. – CBroe just now

This response clarified my query. Thank you.

By allowing the navbar to extend to full width while containing the navigation elements within a .container, you can achieve a clean and organized layout. Take a look at [https://getbootstrap.com/examples/theme/] for an example of a dark navbar that spans the entire width.

You have the flexibility to create multiple full-width sections, each with their own .container div. Check out [https://getbootstrap.com/examples/jumbotron/] to see how the .jumbotron background can stretch to full width with a child .container inside.

Furthermore, there is no rule stating that a .navbar element must always be placed outside a container. Refer to this example: [https://getbootstrap.com/examples/carousel/].

To ensure your grid system works properly and maintain a maximum width where needed, utilize containers strategically in your design.
