Background-size:cover lagging
<p>So I have this issue, on my website i have many sections with background-size:cover property on them, and that causes my website to lag like hell. Is there any solution to contain the 100% width of the picture on every device, but to get rid of website lagging? I've searched some other websites and found, the object-fit:cover on the img tags, but can't seem to implement that on my webpage. Also I compressed every image, so it takes less space. Any answer will be much of a help. Thanks in advance. </p>
