Last updated May 10, 2021 In this example we will cover how to create a circular loading in html CSS. To create a circular loader we will apply the css properties like below border: solid 5px white ;border-top: solid 5px green; width: 50px; height: 50px; border-radius: 50%;
This Circular loading example contains 1 Html file and 1 CSS file to apply style properties to make circular with animation.
