Upside down text uses Unicode characters that appear rotated 180 degrees. These characters are from various Unicode blocks and create the effect of text that appears to be flipped upside down.
Upside down text is perfect for creating playful, fun, or attention-grabbing content. The rotated appearance makes text stand out and creates a unique visual effect that's popular on social media platforms.
Upside down text is different from CSS transforms. While you can rotate text with CSS, Unicode upside down characters work consistently across all platforms and maintain their appearance regardless of browser support or styling.
