Theme and frontend setup for simple and responsive demo pages. Build your library docs quickly with provided styles and html modules. Write with html and js. No build step needed.
Attire is best suited for UI components you want to demo to your users. It is a very reasonable companion for your github pages. Sometimes a markdown generated page can do just fine - sometimes you need more control. Plain html and js will will probably be sufficient if you like to keep things simple. Paste in html, adjust it, include your library distributable via script tag and run it to showcase your module.
You can start by saving demo page html into your new html document. And go on adjusting from there. Or you can examine how others did it.
Here is a list of projects with demo pages built on Attire. If you want your project to be included here - drop me a line.
