I'm trying to insert a gif as the background image but when I make the page fullscreen it zooms in making the background image appear a lot bigger. Is it possible to make the gif stay a certain size when changing the resolution of the page?
.bg {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
background-image: url("space.gif");
background-size: cover;
background-position: center;
background-attachment: fixed;
}
