What characters can be used for up/down triangle (arrow without stem) for display in HTML?

Question

I'm looking for an HTML or ASCII character which is a triangle pointing up or down so that I can use it as a toggle switch.

I found ↑ (↑), and ↓ (↓) - but those have a narrow stem. I'm looking just for the HTML arrow "head".

Answer 1

Unicode arrows heads:

▲ - 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

For ▲ and ▼ use ▲ and ▼ respectively if you cannot include Unicode characters directly (use UTF-8!).

Note: try using the large versions in smaller font.

For more Unicode arrows refer to these links:

Lastly, these arrows are not ASCII, including ↑ and ↓: they are Unicode.
