This is a CSS selector and rule fragment. Here’s a concise explanation and example.
What it means
- py-1 is likely a utility class (e.g., from Tailwind or a similar framework) that sets vertical padding (padding-top and padding-bottom) to a small value.
- [&>p]:inline is a JIT-style (Tailwind arbitrary selector) modifier that applies a style to direct child
elements: make those
display: inline.
Combined effect
- An element with class “py-1 [&>p]:inline” will have small vertical padding, and any direct child
elements will be displayed inline (so they flow within a line instead of producing block breaks).
Example (Tailwind JIT / utility-classes)
HTML:
html
<div class=“py-1 [&>p]:inline”><p>First</p> <p>Second</p></div>Generated CSS behavior (conceptual):
css
.py-1 { padding-top: .25rem; padding-bottom: .25rem; } /* exact value depends on framework */.py-1 > p { display: inline; }Notes
- This syntax (square-bracket arbitrary selector) is supported by Tailwind CSS JIT and some similar tooling; plain CSS does not accept that class syntax — it’s a utility framework feature that generates the corresponding selector.
- If you’re not using such a framework, write the selector directly:
css
.my-elem { padding: 0.25rem 0; }.my-elem > p { display: inline; }
