I know requiring javascript on a webpage has been a hot topic the last couple years.

I'm wondering if someone wanted to use custom elements but still allow the website to be usable without javascript how would they do that?

Would they have to add a <noscript> with regular elements? or is there some way for browsers to know what to fall back to if a custom element is used but javascript isn't enabled?

  • What are you trying to accomplish? Are you trying to figure out what happens to your tags with JavaScript disabled? – svidgen Oct 26 '16 at 23:34

  • The answer to most questions along the line “I want to do fancy stuff with JS but only as progressive enhancement” is “server-side rendering”. – amon Oct 27 '16 at 8:22

    @TheCatWhisperer The top two tags on this site are "java" and "c#" I can almost guarantee none of those questions are language agnostic. Is there somewhere on this site that explains what a good/bad question for this site is? – Tony Brix Jun 14 '17 at 21:31

Unfortunately, custom elements were not designed to be created with html-only syntax1. They were created with the idea to change the DOM on the fly and add your own elements by javascript only.
