How do I make an image that shows up fixed on the screen, but the visible area still scrolls away? Basically, it's like a window. The visible area of the image scrolls away with the page, but the whole image is fixed.
I have too little reputations to write a comment so I have to write a reply.
Like @A Haworth wrote in the comments, you can give your image a class and use position: fixed in your CSS.
for example if you name the class img the css would look like this:
.img {
position: fixed;
}
