The CSS selector they used (`a[href*="://"]::after`) is meant to only target only external links, but assumes any internal links will be using relative paths like `href="/about"`. The problem is that this site uses absolute URLs (`href="https://hhh.hn/about"`) for its nav links, so every link ends up with an icon.

You could fix this by adding an exception to the CSS rule so it skips links starting with your site's name:

  a[href*="://"]:not([href^="https://hhh.hn"])::after

rel="external" solves this.

will fix it tomorrow
