How Can I Create Up and Down Arrowheads in HTML Using Unicode?

HTML and ASCII Characters for Triangle Arrows

In HTML or ASCII, characters representing triangles pointing up or down can be utilized to create toggle switches. While characters like ↑ and ↓ provide triangles with stems, the desired requirement is for just the arrowhead.

Unicode offers several arrowhead characters:

  • ▲ (U 25B2): BLACK UP-POINTING TRIANGLE
  • ▼ (U 25BC): BLACK DOWN-POINTING TRIANGLE
  • ▴ (U 25B4): SMALL BLACK UP-POINTING TRIANGLE
  • ▾ (U 25BE): SMALL BLACK DOWN-POINTING TRIANGLE

To use these characters in HTML, use the syntax [Unicode];. For instance, for ▲ and ▼, use ▲ and ▼ respectively. Note that Unicode characters require UTF-8 encoding.

For smaller arrowheads, Unicode also provides:

  • ? (U 1F841): UPWARDS WHITE TRIANGLE
  • ? (U 1F842): DOWNWARDS WHITE TRIANGLE
  • ? (U 1F843): UPWARDS BLACK TRIANGLE
  • ? (U 1F844): DOWNWARDS BLACK TRIANGLE

However, font support for these smaller triangles may vary, so it's generally recommended to use the larger triangle characters.

For additional Unicode arrows, refer to:

  • http://en.wikipedia.org/wiki/Arrow_(symbol)#Arrows_in_Unicode
  • http://en.wikipedia.org/wiki/Geometric_Shapes

It's important to note that the characters mentioned above, including ↑ and ↓, are not ASCII characters. They are Unicode characters representing arrows.
