title: Does "display:none" prevent an image from loading?
body: <p>Every responsive website development tutorial recommends using the <code>display:none</code> CSS property to hide content from loading on mobile browsers so the website loads faster. Is it true? Does <code>display:none</code> not load the images or does it still load the content on mobile browser? Is there any way to prevent loading unnecessary content on mobile browsers?</p>
