Mid 2019 refreshment

[mischah]

html5please is pretty much unmaintained and needs a major update.

The idea

• review and update each and every feature
• collect and add new features

I hope we find people willing to contribute to make that happen.

How to proceed

New features

If you find a new feature that isn’t part of html5please yet please feel free to comment on this issue and add a new issue before starting to work on it.

• [x] fit-content
• [ ] Web Animations API
• [ ] closest (Element.closest())
• [ ] Variable fonts
• [ ] JavaScript Font Loading API
• [ ] CSS font-display property
• [ ] Font loading API

Update existing features

Feel free to pick a feature out of the posts directory that you would like to work on.

Please create a new issue, use a title containing the feature name and reference this issue to help us tracking the progress.

Please consider the following when updating existing features:

• Does the feature need a status update?
• In case there are polyfills: Are they still relevant and the best choice?
• Are there any additional helpful resources to add to the body of the post or as link via the moreurl property of the post
• Does the file name matches the feature on https://caniuse.com to automatically add a link?

Hej @h5bp/html5please, @paulirish,

would you please consider spreading the word, about this?

Because:

• I would like to get reviews to the PRs I’ll create
• I hope that this will
• I think this refreshment should be accomplished pretty soon.
  • Otherwise I’m afraid that htmlplease will be pretty worthless soon
• I hope that we will engage people to contribute on a frequent basis

[paulirish]

@mischah i just gave a quick review now, but I'll likely be unable to review again. You should feel free to be the primary reviewer now. :)

Thanks very much for spending time on this and whipping it back into shape!

Thanks Paul 😊

Cheers, Michael

shouldn't CSS variables also be added?
