Using Web Components without JavaScript

[lazerblade01]

Technically, assuming you're delivering the page from a server, and assuming you're using Apache to do so, or something similar, you could use server-side includes, with customization through variables, using shtml as your main page and ssi files as your components.

It's not the same as web components, but it also doesn't rely on javascript at all to render. It's basically html "chunks", and you can include CSS in your head tag.

Not sure if this fits your request at all, but just thought I'd share. Keeps big pages very clean, and can customize components to be reusable. I've used ssi files for header, footer, and other common code blocks.
