To make your website more beautiful, you can use different styles and effects for different parts. In this code, we have a photo that is located on the full screen and the entire website is located on this photo. For example, a text box with an almost transparent background is placed on it and the desired text is written inside it. This image has a blur filter and therefore interferes with the texts and photos of the website.
