QR Code Component Challenge with semantic HTML and CSS

For your question about whether or not there's a tool. I'm not what the "right" tool is, but the whole point of alt text for accessibility purposes is that people who can't see the screen would likely need to listen to a screen reader tell them what's on the screen.

So typing any potential alt text into a text-to-speech tool (the same kinda tool a visually-impaired user may themselves use) will let you know pretty quickly whether or not your alt text understandable.

I'm not a pro by any means, and I'm not sure how universal the interpretations of text-to-speech generators are. But I took the liberty of typing "q r code" into a free text-to-speech site, and it sounds exactly right.

This was the site: https://www.naturalreaders.com/online/

Idk how useful this is, but hopefully this helps.

Hello Hayley!

I don't know of any tools for this, but a little guide would be that in case the "alt" attribute had content, it should describe exactly what the image represents or as close as possible to what the image describes.
