Question Square Icon
question-square · Essentional Ui · 6 styles
Solar Icons draws Question Square as part of its Essentional Ui collection. It is one of 139 glyphs in that category and one of 1,246 icons in the library overall, each drawn on the same 24x24 grid so Question Square lines up optically with everything around it. The icon is addressed in templates by the string "question-square", and every style variant resolves from that single name.
What the outline actually encodes is a square container that gives the glyph a consistent bounding box. That places Question Square in the Essentional Ui family, which covers the primitives every interface needs — add, close, check, menu, info, danger and turns up in buttons, dialogs, toasts, form validation and empty states. Teams building literally every application, which is why it is the largest set here reach for this set first. Use Question Square where the label alone would be ambiguous — an icon-only button, a dense table row, a mobile tab bar — and keep an accessible name on the control, because the SVG itself is decorative.
Question Square in 6 styles
Question Square is exported in 6 style variants: Bold, Bold Duotone, Linear, Outline, Broken and Line Duotone. Bold gives you solid filled shapes that hold their weight at 16px and read clearly against coloured backgrounds. Bold Duotone gives you a filled body with a second, lower-opacity layer that adds depth without a second colour token. Linear gives you even 1.5px strokes, the neutral default for dense interfaces and toolbars. A common pairing is Bold for the selected state and Line Duotone for the rest, so the active item reads without a colour change.

Nothing is registered globally by default, so the import list is the bundle. Import QuestionSquareBold from the "@rchernando/solar-icons/essentional-ui" entry point, hand it to provideSolarIcons in your application config or in a route-level providers array, and render it with the solar-icon component. All 6 exports for question-square live in that same entry point, so switching style is a one-line change.

- Import QuestionSquareBold from "@rchernando/solar-icons/essentional-ui", register it with provideSolarIcons(QuestionSquareBold) and render <solar-icon name="question-square" iconStyle="bold" />. No HTTP request is made — the SVG is inlined at build time.
