Adjusting the size of content with CSS

I've been attempting to get an image to cover the entire screen on a device using CSS, but so far I haven't had any success. The image is within an :after pseudo element and content tag. Since it needs to be laid over the HTML, I can't use the image as a background. Any thoughts or suggestions?

@media screen and (orientation:portrait) {
body:after{
    content: url(images/IGOVERLAYPAPI.png); 
    position:fixed;
    max-width:100%; 
    height:auto; 
    z-index:444;
}

Answer №1

If you want an element to completely cover the viewport, you can use this code snippet:

html:after{
    position: fixed;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
}
