Hide "Portfolio" and "Landscape" tags

Using the Perfect Manual Masonry view for the blog layout, which allows me to use “Portrait” and “Landscape” as tags to adjust the size of the masonry item. But that also means that anywhere the tags show on the front end, those two tags are on the list as well. Surprising to me that the theme doesn’t just hide those by default, but I’m wondering what CSS I can add to hide them for my site?

I found another thread asking the same thing (https://kriesi.at/support/topic/hiding-landscape-and-portrait-tags-used-for-masonry-gallery/#post-614528), and it gave the css solution that worked for them, but when I tried to apply it the same way on mine, adjusting the tag id, but it didn’t seem to work.

Any help figuring out the code for my site would be nice, but maybe also a bit of an explanation so others might be able to figure it out in the future, since apparently I couldn’t, based on the last thread.

Thanks!
