Hi @tuanphan:
I used your code and modified it so that the typewriter effect applies to a specific block using an ID selector.
Question for you: is it possible to have this block then inherit the styling from the theme I'm currently using (e.g. have the typed words take on the same font and color and re-sizing etc as another Heading 1 block)?
I don't have any custom CSS and the only change that hasn't been made with the built-in Squarespace options is this typewriter effect.
