Make Snippet appear after custom HTML on a page

Hi there,

we create landing pages for each school we sell to - so there is custom HTML/text on their landing page.

I want a code snippet to appear at the end of the custom area.

I think this may be easy and just involve some sort of

tag but I can’t figure it out.

I need this because when I past the code that is in the snippet into the custom page, it gets sanitized. it is a button to search the page for text.

thanks
