How we build the thing that publishes your changelog, your blog and your release notes.
A table header declared sticky sat still while the rows scrolled past it, with no error anywhere. Two separate mistakes: a wrapper that could not overflow, and the sticky rule on the wrong element. Here is what each one does and how to tell them apart.
A table row and a list item are already self-contained units, which is what makes them quotable away from the page. Both stop being quotable the moment a cell says "same as above". The construction rules, and the cases where a paragraph is the better shape.
Market4 turns one release note into a changelog page, a blog post, a mail-out and a week of social posts — and then tells you which of them brought anyone back.
