Containers:

Containers are used to pad the content inside of them, and there are two container classes available:

1. The .container class in Bootstrap provides a responsive fixed-width container, while the
2. The .container-fluid class creates a full-width container that spans the entire width of the viewport.

Example:

   |---------------------------------------------|
   |                   Navbar                    |
   |---------------------------------------------|
   |                  Container                  |
   |   |-------------------------------------|   |
   |   |             Content Area            |   |
   |   |-------------------------------------|   |
   |                                             |
   |---------------------------------------------|

• 'container': The content area is contained within a fixed-width container. It adjusts its width based on the screen size but maintains a fixed maximum width to ensure readability and proper alignment.

Example:

   |---------------------------------------------|
   |                   Navbar                    |
   |---------------------------------------------|
   |                Container Fluid              |
   |   |-------------------------------------|   |
   |   |             Content Area            |   |
   |   |-------------------------------------|   |
   |                                             |
   |---------------------------------------------|

• 'container-fluid': The content area spans the entire width of the viewport, stretching to fill the available space horizontally. It’s useful for designs where you want the content to extend to the edges of the screen, creating a full-width layout.

Fixed Container:

A “fixed container” typically refers to a design or layout element within web development, particularly in frameworks like Bootstrap, where a container has a fixed width and remains in a fixed position on the screen regardless of scrolling.

Here are some key points about a fixed container:

1. Fixed Width: The container has a set width that remains constant regardless of the screen size. This means the content within the container will not expand or contract based on the viewport size.
2. Positioning: The container is typically centered on the screen horizontally. It stays fixed in its position even when the user scrolls vertically through the page.
3. Responsive: While the container itself has a fixed width, its responsiveness can be managed through media queries and breakpoints. This ensures that the container adjusts appropriately for different screen sizes, maintaining readability and usability across devices.
4. Content Placement: Content within the fixed container can vary and may include text, images, forms, or any other web elements. By keeping this content within a fixed-width container, designers can maintain a consistent layout and design aesthetic throughout the website.
5. Use Cases: Fixed containers are commonly used for headers, footers, navigation bars, or sidebars on websites. They provide a stable framework for important elements of the site while allowing the rest of the content to flow freely.

In summary, a fixed container is a design component in web development that offers stability and consistency to the layout by keeping its width fixed and position fixed on the screen.
