There are still sites like Can I use and MDN for checking if some features are already available for all common browsers, but they are better maintained and many browsers support already quite a lot.

In August 2026, browers can do a lot with pure HTML that needed JavaScript 20 years ago. Examples can be found on Chris Burnell's blog via Leyrer. Infact, I already used some of the mentioned things my self the last time I had to create a website.

Before I read an article about JS free techniques for accordions and dialogs which I couldn't really value, because one important example doesn't work on Firefox yet (the reverse table of content) and the other examples are hidden in a web-editor-page.

CSS

Rebane does crazy shilt with CSS like x86 and Games in the browser via CSS.

JavaScript

You might not need jQuery and the JavaScript.info the modern JS tutorial are probably what one wants to read when learning JS was at the beginning of jQuery. Web components are a nice way to do something similar to AJAX also with just a little JS and not fully blown frameworks like jQuery, Vue, React, etc.

Accessibility

Unfortunately, it seems like this topics hasn't whanged when looking at relatively recent blog posts.
