Image overlay with text on hover

Awesome and very useful.

Thank you!!!!

Well I added to the page header using Page Header Code Injection but it applied the title and subtitle everywhere on the site where poster was used.

I'll the try the design - custom css

I added the above code to the Header Page Code Injection but it affected the entire site; I'll try using the customs ccs and see if that works.

Yes, definitely add it to the Custom CSS section. Were you able to find the data-section0id attribute?
