You've only added

/*make the buttons in the last two sections of site nav less big*/
.nav-tools, .nav-help { gap:.5rem; padding:.5rem }
}

right?

• in general site tweaks:
• /* make font-awesome icons not yellow */ has been changed to /* make icons match normal link/text colors */ and the elements it's applied to has expanded to include svg drawings
• in mobile site fixes/tweaks:
• the contents of /* make primary and secondary nav menu elements the same height */ has been changed to account for changes to the search box font size
• _{I actually updated this again just now.}
• /* make header way shorter [...] */ now includes the new elements.
