## Files

Each icon is drawn on the 16 px grid, and most also on the 20 and 24 px grids (at 24 in three weights: light 1 px, regular 1.5 px, bold 2 px). Show the drawing made for your size, or an exact multiple of it, on whole pixels: 16 for 16 and 32 px, 20 for 20 and 40, 24 for 24 and 48. A size in between or a fractional position blurs it. The code on each icon page is the 16 px drawing, an SVG with fill="currentColor"; the icon page's downloads follow its Grid switch, and npm has the 20 and 24 px drawings too.

The SVG of every style: https://gentleface.com/icons/notdef.json (`svg`).

## Code (line-round)

The snippets are decorative (aria-hidden). For an icon that carries meaning on its own, such as an icon-only button, label the button, or give the SVG role="img" and an aria-label. For another style, take its SVG from the JSON and swap the path `d`.
