Use passive listeners to improve scrolling performance

Post by Chizzle685 »

I use the lightbox gallery - galleria on my homepage. On google Pagespeed Insights I get the message "Use passive listeners to improve scrolling performance". Is there any way to fix this?

All lightboxes are based on third party scripts. I do not have any control over how these scripts work so I cannot change this behavior.
The only way to 'fix' this is by removing the lightbox from your website or try a different lightbox.

Keep in mind however that any script of feature you add to your website will have some impact on the performance.
