Semantic UI is an open-source framework that uses CSS and jQuery to build great user interfaces. It is the same as a bootstrap for use and has great different elements to use to make your website look more amazing. It uses a class to add CSS to the elements. Dimmer is an excellent way to get the user's attention to a specific part of the webpage, ignoring the distractions. A dimmer can be used to blur out its content and gather the user's attention. Semantic UI provides us with the blurring class to blur a dimmer.
