Rooted in the illuminated initials of medieval manuscripts, drop caps carried through the print era and still mark the start of a section in magazine and editorial layouts today.
The classic CSS approach applies `float: left` and a large `font-size` to the `::first-letter` pseudo-element — still the most broadly supported technique. The newer `initial-letter` property has uneven browser support, so many sites keep the float method as a fallback.
How many lines the letter spans (its "sink") is tuned via `font-size` and `line-height`. A little `padding` next to the drop cap keeps the adjacent body lines from butting up against it awkwardly.
When to use
Best for the opening paragraph of an article, blog post, or magazine layout. Overkill for short UI copy or card descriptions that don't need to feel like a chapter opening.
