Previous default UA styling for Customizable `<select>` on the left. Current default UA styling in Safari 27 on the right. Thoughts? We really wanted to give web developers a better starting place. 30 years of struggling to style form controls is enough.

What do you want the new default styling to be for HTML fieldset?
Here’s what it’s been forever — a box around things, with the legend text placed over the middle of the line at the top left. (See https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/fieldset for more.)
If you write: `fieldset { appearance: base }`, what do you want the styling to be in the future??

Do you make websites / web apps? What do you wish for <select> listbox?
This is the HTML. Currently, it creates a listbox with 4 options showing:
`<select id="foobar" multiple>`
If you want 6 items showing, you write:
`<select id="foobar" multiple size="6">`.
If you want a pulldown menu that allows multiple choices instead:
`<select id="foobar" multiple size="1">` — but only in Chrome.

Do you make websites / web apps? What questions might you have about Safari on HomeView or on MacBook Pro with PROLED XDR Display?
#css #html #javascript #webdev
Have you been making websites for years? How are you feeling about the current state of things?
I’ve thought for years the answer should be no styling! Be like a `section` or `div`. Let the developer turn it to anything.
