font-family: Inter; /* whatever your preference is */

Re the tags, I assume you mean tags in Preview, so you can centralize like this:
/* ====== Tag Pills ======== */
.tag:not(.token) {
text-align: center;
}
Incidentally, if you are interested in other snippets, there is a collection on Github. The link to the Github repository is given in the OP at the top of this page.
Enjoy.
