ObsoHTML is a Node.js script designed to scan HTML, PHP, JavaScript, and TypeScript files for obsolete or proprietary HTML attributes and elements (in scripts, it would catch JSX syntax). It helps you identify and update deprecated HTML code to be more sure to use web standards.

An even smaller subset of htmx: it loads HTML onto any element in the page on request, and that's it.

The HTML standard for web developers

Didn't read, but it can be useful someday

A HTML validator aiming to be better than the current W3C HTML validator.

There is a descriptive page: https://validator.w3.org/nu/about.html

A great serie of post! Short, simple and clear.

Simple projects that are handy to learn HTML, CSS and Javascript

In a nutshell, the purpose of REVENGE.CSS is to apply visual regressions to any markup anti-patterns. It makes bad HTML look bad.

Interesting.

Passing CSS variable errors can be useful too.

There are also useful patterns.

They are different. HTML attributes are set on the HTML tags, whereas DOM properties are set in JS on the HTMLElement.
This post highlights the differences.

Stay close to the standard. Expose APIs instead of wrapping them.

The author asks for less HTML-in-JS and demonstrates it with the Next meta tags example.

Whenever a problem can be solved by native HTML elements, the longevity of the code improves tremendously as a result. This is a much less alienating way to learn web development, because the bulk of your knowledge will remain relevant as long as HTML does.

The author tried it with PHP, but it somehow didn't work.

The Mozilla Documentation Network published a curriculum to become a frontend developer.

It seems to contain relevant resources, also for confirmed developers.

How much text is displayed compared to the html markup

It corrects and cleans up HTML and XML documents by fixing markup errors and upgrading legacy code to modern standards.

A complex challenge as the official standards are implemented in few websites.
Guesses have to be made.

Use emojis as html tags.

It has more impact than "semantic HTML" but it they share common goals.
