I'm looking to create an interactive animation that activates when the cursor hovers over it. The animation will involve an abbreviation expanding into its full form, for example, hovering over "CSS3" could make it expand to "Cascading Style Sheets" with "ascading" appearing between the letters "C" and "S" in a typing effect manner rather than instantly. Is it possible to achieve this using only CSS3? (Editor's note: I assume he means having the new letters typed out instead of just appearing all at once)
