Despite the fact that this Hugo instance has been around for 3 years, I’ve never added tags on my posts. It is bit awkward to manually add “Go” when a post itself contains “Go”.
But, well, I’ve changed my mind.
Hugo’s Taxonomies page explains the overall and Taxonomy Templates page describes the way to show taxonomies in templates. I also added a bit of CSS to make it looks nice. I still cannot write Flexbox without googling. A Complete Guide to Flexbox is my go-to.
The only downside would be losing “3⁄100”-style count-up. I’m going to do that every 10 posts or so.
