What is a progress bar?

What is Bootstrap’s collapsing elements?

The collapsing content feature in Bootstrap’s CSS framework lets you collapse an element when it reaches the bottom of the page. It comes in handy for when you want to create a sidebar that appears on smaller screens or if you just want to save space.

Scrollspys typically appear as a thin rectangle below the website’s content area and move relative to the document as the user moves their mouse up and down.

What is a toast and what are the main components of a toast in Bootstrap?

Toasts are the little squares that appear towards end of a website. These are usually shown as a content box containing text, images, buttons and other elements. Toasts are also an important component in Bootstrap layout as they provide a way to break up content visually and build a consistent theme.

– Title – Content block with text

– Button – Text with image next to it

– Image – Static image
