Semantic UI is an open-source development framework that provides pre-defined classes to make our website look beautiful, amazing, and responsive. It is similar to Bootstrap which has predefined classes. It uses jQuery and CSS to create interactive interfaces. It can also be directly used via CDN like bootstrap.

The Semantic-UI Loader States are used to represent the different states of a loader element. There are three types of loader states that are – Indeterminate, Active, and Disabled.

Semantic-UI Loader States:

• Indeterminate: It is used to display the loader that is unsure how long a time a task will take.
• Active: It is used to display the loader that can be active or visible.
• Disabled: It is used to represent the loader that can be disabled or hidden.

Syntax:

<div class="ui segment">
    <div class="ui active dimmer">
        <div class="ui Loader-States text loader">
            ...
        </div>
    </div>
</div>
