Need Experienced Dev to look into something

I'm planning to do parasite SEO on a certain platform, and I found someone doing exactly what I want to do, so i have examples to show.

The platform allows you to upload content from your already existing site, but it has certain elements that I need to be blocked.
The people already doing this manage to block or hide those elements by inserting code on their own site. I have examples to show from page source.

I simply need someone to replicate that code and make it work on my site.

Please contact me only if you have good experience in HTML/CSS

Thanks
