I built a fast HTML/CSS editor with live preview
I kind of don't like that it debounces the update. I made something similar as a sandbox for AlpineJS: https://awesomealpine.com/play supports typescript (esbuild wasm), tailwind (with the tailwindplays js script), css and html of course. The share links are handled with a Cloudflare KV , and when retrieving one, it is actually server rendered ( and cached ) which was a fun challenge. More on reddit.com

r/webdev on Reddit: Looking for a embeddable HTML / CSS editor and viewer
October 24, 2023 -

Hi r/webdev !

I am a K-12 computer science teacher in the Netherlands and I am working on a online learning method for my students to learn the basics of HTML & CSS programming (this being their first encounter with CS). For this I use an environment in which I can use HTML to embed certain editors.

My question is: do you happen to know a embeddable HTML editor and viewer side-by-side so that I can let my children try out changing HTML code quickly on the go? What I am basically looking for is the editor and viewer combo of w3schools examples ( like this one ) but then embeddable in my own HTML environment and where I would be able to preset some code.

I already tried to simply make an <iframe> of one of those w3schools tryout pages, but w3schools doesn't allow these pages to be used in such manner.

Many thanks in advance for your help!
