How to know and reduce unused JS and CSS code

Hello,

I runned a google lighthouse check on my website and it shows that I need to reduce JS execution time and main-thread work. I am wondering how can I do this on Webflow. Any advice, articles or videos would help.

Thank you!

hi @DAJY,

Just from playing around with your site in DevTools, it looks like your GTM is running quite a few scripts - Iā€™d recommend checking in Google Tag Manager. It seems to be mainly Drift responsible for slowing the page down.
