Yes, prefetching will still work.

It will also improve the page loading performance a little bit because prefetching will start already halfway into the loading of the page if it is in the head.

Moving it to the bottom of the , it will only start after all the important stuff is done.

Fun fact: tags actually block your application load. If you have 100 images on your page, the browser will download all 100 of them before it renders your page.

That is completely false. If that were true no one would ever see the text of their web page with empty boxes where the images would be, followed by the images loading in those boxes. The entire point of DOMContentLoaded vs. load events is that the HTML elements can be completely parsed before the external page resources have finished downloading and rendering. Additionally, no one would ever need a load event on an img because, if that article were true, all images would be loaded by the time you saw the page.

=============================================================

While the JavaScript runtime is single threaded, the browser client is not. "Resource files" (any file that is referenced by the .html page being parsed) are downloaded simultaneous to the page being parsed. There may be a maximum amount of resources that the client will download at the same time (years ago in IE the limit was 10 by default, but I think that's been upped since then).

Oftentimes when you load up a web page, you'll see all the text of the page first (because text loads really fast) and the images load after that. It's simply because images take longer to download than text, not that the images wait to begin downloading.

This can be verified by looking at the Network tab of your browser's development tools while a page loads. You'll see a variety of resources being downloaded simultaneously with the page.

If you don't mind loading it asynchronously you can do it like this:

Here is a minimal example that demonstrates how to store and retrieve a file handle (a FileSystemHandle to be precise) in IndexedDB (the code uses the idb-keyval library for brevity):

Courtesy of AWS tech support, the answer is:

• Access-Control-Request-Headers
• Access-Control-Request-Method
• Origin

According to this fixed bug transferring file handles via postMessage() is implemented and should work, however, only for same-origin contexts. If it doesn’t work, probably your origins are different.

role="tab" must be a direct descendant (or contained within an element with no semantic meaning) of a role="tablist" element. To be fair this is really not clear in the WAI-ARIA spec but I have hit this issue myself before. (you can use aria-owns to make the association but that is more for if the tabs sit outside the tablist element)

Because your is wrapped in a this breaks the pattern.

I have tested it and it appears to work in JAWS and NVDA, but just to be safe (as there are loads of screen readers and some of them may not like your implementation) I would make a minor adjustment.

Remove the

A second option is to make the

I personally am not a fan of the second option but I can see why some people may choose to do that.

One other thing I would suggest is to put the tabs and the tabpanels inside

and
• .

  For screen readers that don't support tablist this means a user still gets an announcement of "1 out of 3 options" etc. So it makes it easier to understand they have options.

  Also it is recommended that each tabpanel has a tabindex="0" to aid navigation once a tab has been selected. This is one of those very rare circumstances where making a non-interactive element focusable is encouraged.

I think u need to remove from your base config or add to you development config.

u trying to replace but in your base config u have
