Client side optimization

Hello! Can you please tell me why google pagespeed shows "Reduce the size of the DOM structure to 1,322 nodes" - site remobi.tk; What does this number mean and where does it come from? How can this problem be corrected?

Answer 1

All the recommendations are there. Read them and follow the link provided .

Browser engineers recommend pages contain fewer than ~1,500 DOM nodes. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer style calculations, and produce costly layout reflows. learn more.
