triptych

If you do not wish to use any javascript, you can use iframes and the "target" attribute on links and forms: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#... However the user experience is pretty rough, which is why people typically don't use this feature. If you want a minimal amount of javascript to achieve this, we (the htmx folks) also have fixi: https://github.com/bigskysoftware/fixi Finally, we are working on introducing general transclusion into the HTML spec itself with the triptych project: https://github.com/alexpetros/triptych however that is a ways off (if ever)

Alex and (to a much lesser extent) I are trying to get a modernized version into the HTML spec: https://github.com/alexpetros/triptych

you can support and publicize the triptych project: https://alexanderpetros.com/triptych/ https://github.com/alexpetros/triptych?tab=readme-ov-file

Strongly disagree. There are so many places where the browser itself provides a reasonably good user interface, and web developers fuck it up - scroll hijacking and history manipulation being two of the biggest examples. I suspect that one of the reasons we ended up in JS-hell is that HTML and browser built-in functionality lagged behind user expectations for so long. If browsers had offered the equivalent of AJAX and DOM element replacement early on, heavy use of JS might never have caught on. (Consider Triptych [https://github.com/alexpetros/triptych] as the baseline for what browsers should have been providing since 2005 or so.)

There’s a draft proposal to get some of HTMX in the browser: https://github.com/alexpetros/triptych
