Theme Sydney/child

Hello, I have installed the Sydney theme and activated the Sydney Child theme.

The issue I’m having is How to remove the Blog post Tags?

Here are some samples of what I tried:

.tag-links {
display: none;
} then this,

.cat-links { display: none; }
.cat-links + .meta-sep { display: none; } then this,

.tag-links { display: none; }
.tag-links + .meta-sep { display: none; }

I have searched through a multitude of forums and tried putting various codes into the “simple css” box in the Customise panel, but nothing has worked so far, tips from someone who has done it would be appreciated.

Thank you in advance.
