You’re referencing a CSS selector/utility pattern. Here’s a concise explanation and examples.

Meaning

  • py-1 a utility shorthand (common in frameworks like Tailwind CSS) that sets vertical padding (padding-top and padding-bottom) to a small size (1 unit). The exact value depends on the framework’s scale (e.g., Tailwind’s py-1 = 0.25rem / 4px by default).
  • [&>p]:inline a Tailwind-style arbitrary selector that applies the utility inline to every direct child

    element of the selected element. It uses the JIT arbitrary selector syntax: [&>p]:.

Combined usage examples (Tailwind-like)

  1. Apply small vertical padding to a container and make direct paragraph children inline:
  1. With HTML:

First

Second

Result: container has small vertical padding; both

are rendered inline.

Notes

  • Requires a CSS utility framework that supports arbitrary selectors (e.g., Tailwind JIT). Plain CSS won’t recognize the [&>p]:inline class.
  • Equivalent plain CSS:
    .container { padding-top: 0.25rem; padding-bottom: 0.25rem; }
    .container > p { display: inline; }

Adjust the padding value to your framework’s scale if not using Tailwind.
