Font size of title in masonry gallery

Hi
i need to change the font size of “av-masonry-entry-title” in all single pages which contain a masonry gallery
I gave a class “kursmasonry” and made it like this:

#top .kursmasonry .av-caption-style-overlay .av-masonry-entry .av-masonry-entry-title {
	font-size: 1.7em !important;
	color: #f7f7f7 !important;}

IT WORKS

I have a page (overwiew) which has a masonry element (not gallery!).
Here i pull all pages – this is the overwiev of all classes and courses i give.
I need to have another font size here but it does not work

I work since hours but i cant make it work.
I even cant get it with the page id:

.page-id-32278 .av-caption-style-overlay .av-masonry-entry .av-masonry-entry-title {
	font-size: 3em !important;}

This is the code of the page:

[av_masonry_entries link='kurskategorie,3792,3790,3787,3788,3791,3789' wc_prod_visible='' wc_prod_hidden='hide' wc_prod_featured='' prod_order_by='' prod_order='' date_filter='' date_filter_start='' date_filter_end='' date_filter_format='yy/mm/dd' period_filter_unit_1='1' period_filter_unit_2='year' sort='yes' query_orderby='date' query_order='DESC' caption_elements='title excerpt' caption_styling='overlay' caption_display='always' size='fixed masonry' orientation='' image_size='masonry' gap='large' columns='2' av-medium-columns='' av-small-columns='' av-mini-columns='' items='12' paginate='load_more' color='' custom_bg='' overlay_fx='bluronhover' animation='' img_scrset='' lazy_loading='enabled' id='workshop' custom_class='' template_class='' av_uid='av-l306034u' sc_version='1.0']
