There are some situations where it is needed to hide some content on a webpage without affecting the layout of the page. Bootstrap uses the CSS visibility property and provide two classes visible and invisible to control the visibility of an element on a web page.
These classes do not affect the layout i.e. invisible elements will still take up space in the layout. Content will be hidden both visually and for screen readers.
This class of bootstrap is used to hide an element from the page. In the below program the heading h2 “Bootstrap Tutorial” is made hidden using this class. This class basically uses the visibility property of CSS and set it’s value to hidden. Even though the heading Bootstrap Tutorial is invisible, it’ll still take up space in the layout.
