Code in Quarantine
In the current paradigm, we often work with components and have a 1:1 relationship of HTML to CSS. This makes maintenance more predictable. However, it also pronounces the problem of rarely used code—which can be useful to put in quarantine.

In Critical Defense of Frontend Development
The field of frontend development is in another crisis, largely due to an incomplete, misinterpreted definition and a bizarre mess created by “web development as a commodity” and “web development as software development.” How frontend development is more than development, and what we can (and should) do.

Ignore AMP
In 2018, my recommendation was to avoid AMP, to use AMP for the most relevant pages, or to use AMP only. In 2020 my recommendation is to ignore it, because AMP largely appears meaningless now. Upgrade Your HTML II gives an opinionated idea why.

On Writing Better Markup
