## Importance of loader

These days if a website takes more than a few seconds to load, people tend to close the page and move on.

CSS loaders help retain a site’s traffic. It increases the **loading speed** and **entertains users.**

Unlike a gif, a CSS animation avoids the image request. This results in less bandwidth consumption and a faster loading process.

## Automation

Now lets understand how a loader works and how to configure.

Loader can be configured in two ways

1. Configuring at Pre/Post actions
2. Configuring in action class

For any way to make the loader works, We need to create an UI element with the element type as loader.\
Wait value provided in the UI element will act as the maximum time in seconds to wait for the indivisibility of element
