Hi!

1. I'm really glad you care about accessibility. I would like to ask a few important things for this. I use the navigation part of the SP. It looks like this:

   <nav role="navigation" aria-label="Menu">

   But it's all on the page and that's a problem. Each such element should have a unique aria-label.

2. I found an interesting bug in the HELIX framework. I don't use the framework's menu system. However, it does incorporate the off-canvas menu type into the page. The layout does not contain a module position pointing to a menu. There is no menu type module on the Joomla page. What I'm using is an SP module that has a button group. This is interesting because since off canvas is a hidden element, the menu links must contain aria-hidden="true" (ARIA). I noticed this when I checked the accessibility.

3. For every element that uses the LINK part, couldn't it be expanded with 1-2 things. For example, aria-label, role, etc.?

4. ARIA verifiers indicate that several areas are not identified, that the page does not use such markers: Technique ARIA11: Using ARIA landmarks to identify regions of a page. banner, navigation, main, region,form, search,complementary, contentinfo. https://www.w3.org/WAI/WCAG22/Techniques/aria/ARIA11
