py-1 [&>p]:inline

You’re referring to a Tailwind CSS utility-like shorthand: py-1 [&>p]:inline.

Explanation:

• py-1 — sets vertical padding (padding-top and padding-bottom) to 0.25rem (Tailwind’s spacing scale 1).
• [&>p]:inline — a Tailwind JIT arbitrary selector that applies the inline display to direct child

  elements (the selector is & > p).

Behavior together:

• The element gets small vertical padding.
• Any direct child

  becomes display: inline; (so its block behavior is removed; margins, line breaks, and width behave like inline content).

Notes:

• Requires Tailwind JIT / arbitrary variants support.
• The exact spacing value depends on your Tailwind config if customized.
• [&>p]:inline → for nested, use [&_:where(p)]:inline or a different selector.
