HTML Triangle Character Options for Displaying Stemless Up/Down Arrows

To display a triangle pointing up or down without a stem, several HTML or ASCII characters can be utilized. Here are a few options to consider:

Unicode Arrows:

For accurate and flexible representation, Unicode arrows offer a wider range of triangle characters. Some notable options include:

• ▲ ( U 25B2 ): BLACK UP-POINTING TRIANGLE
• ▼ ( U 25BC ): BLACK DOWN-POINTING TRIANGLE

HTML Entities:

If direct Unicode inclusion is not possible, HTML entities can be used as follows:

• ▲ for ▲
• ▼ for ▼

Small Triangles:

Unicode also offers smaller triangle characters with slightly reduced font support:

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

Considerations:

• Stemless triangle characters are not part of the ASCII character set. They belong to Unicode.
• For better visibility in smaller font sizes, it is recommended to use the larger triangle characters (▲, ▼).
