How to create a pre-loader using CSS?
Preloader is used to show the loading process of a web page to the user. It is what we see on the website before the page loads. It is used to keep the users intact with the page till the contents load on the page. The preloader varies from website to website. This preloader is designed using CSS.
Pre-loader using CSS
The most common preloader are the spinners. To create a spinner, we add the following properties.
border property to add border size and border color to the spinners.- spinners are the circles so add
border-radius to add a circled border.
animation to add a spinning effect to the spinners.- The
height and width of the preloader.
- CSS transform property is added to rotate the spinners.

}
@-webkit-keyframes preloader {
0% { -webkit-transform: rotate(0deg); }
100% { -webkit-transform: rotate(360deg); }
