CSS Optimization: Does "display:none" Truly Prevent Image Loading?

Does the "display:none" CSS property effectively prevent images from loading on mobile devices to enhance website speed?

While responsive website design recommends using "display:none" to hide content from mobile browsers, its effectiveness in preventing image loading remains unclear.

Answer:

Browser Behavior:

Current browser technology allows for intelligent handling of CSS properties. If a browser detects that an image with "display:none" is not required, it may skip the loading process.

Image Metadata:

Even with "display:none" applied, the image's size and other metadata can still be accessed by scripts, suggesting that some loading might still occur.

Browser-Specific Behavior:

Chrome версии 68.0 and above have been observed to prevent image loading if the parent element is hidden using "display:none."

Alternative Solutions:

If preventing loading is crucial, alternative methods include:

• Removing the element from the document
• Setting the src attribute to "data:" or "about:blank"

Limitations:

"display: none" does not prevent image loading if the image appears on the first screen without lazy loading. In this scenario, the image will load but remain hidden.
