  • It requires use with the default grid system.
  • To establish width for the layout to give web content.
  • To provide responsive fixed behavior of any web project.
  • To sets the content margin dealing with the responsive behavior of your layout.

Bootstrap has the default class or predefined class is “.container” & “.container-fluid” class for  layout. Containers are used to contain, pad, and (sometimes) center the content within them. While containers can be nested, most layouts do not require a nested container.

Basically, there are three types of container classes available in bootstrap:



  1. Default-Container(container)
  2. Responsive-Container(along with sm, md, lg, xl, xxl)
  3. Fluid-Container(container-fluid)

 

1. Default-Container: The default container uses ‘.container’ class. It provides a responsive fixed-width container.

Syntax:

<div class="container">
  <!-- Content here -->
</div>

2. Responsive-Container: Responsive containers are responsive in nature. Responsive containers allow you to specify a class that is wide until the specified breakpoint is reached, after which we apply max-widths for each of the higher breakpoints.

Syntax:

<div class="container-sm">Wide for small breakpoint</div>
<div class="container-md">Wide for medium breakpoint</div>
<div class="container-lg">Wide for large breakpoint</div>
<div class="container-xl">Wide for extra large breakpoint</div>
<div class="container-xxl">Wide for extra large breakpoint</div>

3. Fluid-Container: Fluid-container uses the ‘.container-fluid’ class. It is used for a full-width container, spanning the entire width of the viewport.

Syntax:

<div class="fluid-container">
  <!-- Content here -->
</div>
