HTML elements and controls

niso implements HTML’s elements with their usual meaning, parsing, and default style. Every element interface, with its members and their C functions, is in the Web API reference under HTML elements (generated from idl/).

These elements are drawn as native controls while their appearance is auto:

Element	Apple platforms	Android	Linux (iced)
<input type="checkbox" switch>	Toggle	Switch	toggler
<input type="range">	Slider	Slider	slider
<progress>	ProgressView	linear progress indicator	progress bar
<button>	button	Button	button
<input> (text, search, email, url, tel, password, number), <textarea>	TextField, TextEditor	text field	text input, text editor
radio group (<fieldset> or role="radiogroup")	Picker	button group or radio rows	radio buttons

Everything else, including <select>, checkboxes, plain radio buttons and date inputs, is drawn as a CSS box for now. Sizes, styling and the rules for radio groups: Native controls.
