The idea
Everything at once: centre the title, stretch its letters, uppercase it, underline it, and give the body a relaxed line-height with an indented first line. Match all three measured pieces — the title text, the body text, and the body block.
This level needs text-align, letter-spacing, text-transform, text-decoration, line-height and text-indent. margin, padding and height are off-limits — they would fake the alignment, spacing and line-height without teaching the text properties.
