Script for, insert class A after class B, don't have access to A
I’m working on a page that has a chart that has all the code in the back end, so I can’t access the HTML/CSS for it.
However, I want to add a banner inside this chart. How can I get HTML to insert itself after a certain div (that I don’t have access to)?
So for example:
*I want to insert the new class “offer-Banner” here but again I don’t have access to the other surrounding code.
Thanks for any help with this.
