How to break the lines on summary block titles

Thanks to the valuable answers of @Paul2009 in this platform, we managed to understand how to break lines at gallery titles, grid titles and product titles (i.e. the product title in the 'shop' page).

We tried to apply the same methods to break the lines on summary block titles, but unfortunately never managed to do so.

Would there be a solution for this particular situation?

Here is the link of the concerned page: https://www.thelabfragrances.com/earl-grey

As seen there; we have the following structure:

Earl Grey 30ml Perfume

Oil

S$78.00

..

Whereas we would like to have:

Earl Grey 30ml

Perfume Oil

S$78.00

..

Thank you very much.

It can be achieved in the same way, with slightly different code once the delimiters have been added.

(Note that you currently have errors on your site because you have jQuery code without the library)

Thank you very much @Paul2009 for the answer. Unfortunately, we could not figure out what to do based on your explanation.We would be really glad if you could share a brief code encapsulating your message. Thank you.
