Adapt the display of media & images

Resize media and images depending on whether the user visits from a mobile or a computer.

Reduce the weight of page resources

Lazy loading

Load only what is visible on the screen instead of the entire page.

Instead, load resources asynchronously, especially for CSS, JS and fonts.

Cache static elements by identifying dynamic and static content, then define the rules for caching static content.

Load and execute scripts after priority content.

Shorten JavaScript execution time
