CSS letter-spacing can be used creatively to build text reveal animations without JavaScript. By setting a large negative letter-spacing value, characters overlap and become visually hidden; animating back to zero or positive values reveals the text. Combined with color transitions, overflow: clip, text-indent, ::first-letter, and ::first-line pseudo-elements, you can build interactive effects like checkbox-triggered text swaps and acronym expansions on hover. Code examples are provided for each technique.
