Ever tried. Ever failed. No matter. Try again. Fail again. Fail better. You won't believe what you can accomplish by attempting the impossible with the courage to repeatedly fail better.

Random CSS Property

caret-color

The caret-color CSS property sets the color of the insertion caret, the visible marker where the next character typed will be inserted. This is sometimes referred to as the text input cursor. The caret appears in elements such as <input> or those with the contenteditable attribute. The caret is typically a thin vertical line that flashes to help make it more noticeable. By default, it is black, but its color can be altered with this property.
