Hi there,
Are there ways to reduce the number of DOM elements? I’m not sure if this is caused by one of the plugins I’m using or not.
Generally, the way to deal with this is to reduce the number of contents you’ve added to the page/post.
If it’s possible to put all things in 1 block, go for it.
If you’ve added forms that you find unnecessary now, remove them as well.
This is pretty tricky to do considering the context of your site as the contents added are a lot and it looks like all of them are important.
If you can rewrite your content to make it shorter, that would be very ideal to reduce the number of elements.
