It uses web tech so all the accessibility is built right in!

"Web tech" could mean WebGL or Canvas, which are not accessible. Does it create HTML elements?

I'd check myself, but none of your examples seem to be available to just look at without cloning the repo locally.

If you dig into the library a bit more you’ll find that it renders native HTML elements.

That doesn't mean much on its own. 30 nested <div>s with auto-generated IDs and all input handled in JS also counts as "web tech", but I wouldn't want to subject any screen reader user to that.

In another comment you mentioned some ongoing work on a native back-end, how is the accessibility story going in this scenario?

We’re leveraging the work done by Druid so the plan is to use AccessibilityKit as the foundation. Our native renderer is essentially a GPU-accelerated HTML/CSS renderer so we’ll pull in all the accessibility tech there. We don’t want people to learn anything new to get started, so sticking with web foundations is smart even if it’s not as great as a bespoke solution.

Thanks for your answer. This part confuses me a little bit though:

> Our native renderer is essentially a GPU-accelerated HTML/CSS renderer

You'll just implement a subset of an HTML/CSS renderer that is capable enough for a specific subset of HTML and CSS that Dioxus generates, you're not planning to develop a fully browser-compliant HTML/CSS renderer, right?

We’ll implement what it takes to hit the majority of CSS we run into. The Rust ecosystem has some great packages for CSS and layout (we and Bevy comaintain Taffy) so at a certain point it’ll be filling in the blanks.

Being browser compliant would be great, but just being 70% of the way there would be cool too.

Thanks. I think aiming a 70% compatibility is a realistic goal, going up to 90% would probably need 10 times more efforts, and 95% ten times more, with 100% being unreachable anyway because no two browser behave exactly the same.
