To make your website more beautiful, you can use codes that make your website unique. One of these codes can be used for the background of your website. In this code, we also have a circular background for the website background. There are three purple but transparent circles that are constantly getting bigger and smaller. These three trees are inside each other. In the center of these circles is a title written in white.
