The site nativeformelements.com is a great source to learn about the behaviour of native form fields. Unfortunately a lot of details are missing. This is proposal to update.
The page is a grid with the states of the all available input fields.
First of all it is my test page for the work in the field of accessibility. I use it to learn the behaviour of native elements.
The default of the page is without any design. Just a few basics for light & dark mode as well as hight contrast mode.
- Design https://developer.mozilla.org/en-US/docs/Learn/Forms/Styling_web_forms
- Integrating a form design system like https://purecss.io/forms/
