Hi Jesper,

It looks good!

A couple of things we should look at before we merge:

• Dispatch an event on input as we do on change so you can listen for both input and change events on uui-textarea.
• The label should follow the same styling as the uui-input label. Bold and with the same bottom margin to the textarea.
• Add some padding inside the textarea. It should follow the same look as the uui-input.
• Set the font family to "inherit" to use the correct font.
• When we have added support for maxlength then I also think we should consider support for minlength. It is a "nice-to-have" now, we can always add it later.
