Interactive Demo

The rusty swing set creaked a lonely lullaby in the twilight, shadows lengthening like grasping fingers across the dew-kissed grass. A lone dandelion seed, adrift on the breeze, whispered secrets of faraway fields, of dandelion suns and galaxies spun from fluff.

  • noneOutline is not drawn, color and width are ignored.
  • dottedA series of round or square dots.
  • dashedThe outline is a series of short line segments.
  • solidThe outline is a single line.
  • doubleThe outline is two single lines. The outline-width is the sum of the two lines and the space between them.
  • grooveLooks as if it were carved in the canvas. (This is typically achieved by creating a "shadow" from two colors that are slightly lighter and darker than the outline-color.)
  • ridgeThe opposite of groove the outline looks as though it were coming out of the canvas.
  • insetThe outline makes the box look as though it were embeded in the canvas.
  • outsetThe opposite of inset the outline makes the box look as though it were coming out of the canvas.
