WordPress speed optimization DOM size

[Molydoly]

Hi, 
Hoping for your good health. I have a website which has developed in PHP WordPress. It is working fine but i am facing speed issues.

In GTmetrix is showing good results but in page speed insights there are different types of errors. I am unable to resolve it.  
Kindly any developer guide me how to resolve it. 
My website is: https://printerloop.com/

Thank you.

You could try to:

1. Reduce the number of sections of the page.
2. Remove hidden elements.
3. Switch to a simpler or less overloaded theme.
4. Limit the number of posts/products displayed on a page, etc.
