I am making a website and on most websites it has a big image with massive text in it which says Welcome or something I have replicated the same thing but I was wondering is the image in the photo behind the OptimisePCs possible to achieve with plain CSS so no image, this is for performance reasons because people have to download the image to see it which takes time.
