Headline Shadow

Hi,
I was trying to follow this thread https://kriesi.at/support/topic/is-it-possible-to-create-this-headline-effect/
to create a shadow effect to the headline and subheadline in a section of the page, yet I had no results.

Can you help with the right code?

I activated both ALB and named the section ‘venue’, then also added the code for the page id, since I saw nothing changing.

Here’s the code I added:

.venue .av-special-heading {text-shadow: 0px 1px 1px #000 !important;}

.page-id-2650 .av-special-heading.ab-headline2 {
text-shadow: 0px 1px 1px #000 !important;
}

this is the page where I’d like to get the shadow:

And this is the section where I want the headline and subheadline to display a shadow:

Thanks for your help :)
