- Converting existing pages into a hugo website
.htmllinks should work
- Atom feed: Still has validation errors
- html5: Fix all validation errors
- Hide emails from spam bots
- rel="noreferrer" attribute missing on all links
- rel="noopener" attribute missing on all links
Have a look at README.md how to test it with hugo's internal webserver.
This is my very first MR - feedback is very welcome.
If this is not the right way to review and discuss, please let me know.
