Favicon manifest

Post by RSteinwand » Thu Oct 08, 2015 2:50 pm

Hi Albert,

This code:

Code: Select all

<link rel=manifest href=/manifest.json>
... give me this error:
The "rel" value specifies the following unrecognized or invalid link type: "manifest". Visit http://www.w3.org/TR/html5/links.html#linkTypes and http://microformats.org/wiki/existing-r ... extensions for more information or to register a new extension.
More info on linking to a manifest:

Code: Select all

<link rel="manifest" href="manifest.webmanifest">
http://www.w3.org/TR/appmanifest/#using ... a-manifest

Thanks.
Rick

Thanks Rick. I discovered this myself when working on "favicon stuff" and have already fixed it for the upcoming v16 release.

I recently did that enormous task myself. I can't believe all the images you have to have polluting your website root.

Then when I thought I was all done, I checked the 404 logs and had to add more images. For example, I had a favicon_32x32.png image, then the 404 logs showed lots of requests for favicon_32.png. This went on for several other sizes. Figure that out. After all the Windows, Android, and Mac images and making sure they're all optimized and long expirations, it turns out to be a several day affair.

Yep!

It is indeed a much bigger task than I would have ever imagined!

However, I was really impressed with how that site I recommended (http://realfavicongenerator.net/) helped with it. Did you try using that favicon generator site?

I see you passed on a bunch of the iOS icons. You might want to check your 404 logs to see if you have any favicon issues. I have it lucky in that I get a 404 report in my email inbox every morning so it's easy for me to check for missing files.

Due to size concerns, my favicon.ico has only the 32x32 size.

Yes, I thought that was too much "junk" to add to my site, especially when CSE HTML Validator is Windows desktop software... I do have the icons on the server though.

I really like the idea of using a manifest file so you don't have to gunk up every web page with excessive meta data.

I checked my log for lines with "favicon" and "404" and only found them for a domain that I don't have a favicon for so it looks good over here.
