Tips
- Always
observebefore interacting to get current refs - Use
blockimagesfor faster page loads - Use
typeinstead offillfor search boxes (triggers autocomplete) - Refs (
r1,r2) are more reliable than CSS selectors observeonly returns elements visible in viewport - usepagedownto see more- Re-observe after any navigation or DOM change
