Image Cover - Script Codes HTML Codes

<!DOCTYPE html>

<body> <h1>Image Cover</h1>
<h2>Using &lt;img&gt; to do the same thing as background-size: cover.</h2>
<p>Why do this? Because the &lt;img&gt; tag gives us the ability to use picture and srcset. You could switch out images with CSS background-image, but that's not as friendly in some systems and can be a pain. A little CSS and JS magic is all it takes.</p>
