Mastering margin collapsing

掌握边距重叠

Top and bottom margins of blocks are sometimes collapsed into a single margin whose size is the largest of the margins combined into it, a behavior known as margin collapsing.

Margin collapsing occurs in three basic cases:

• Adjacent siblings
• Parent and first/last child If there is no border, padding, inline content, or clearance to separate the margin-top of a block from the margin-top of its first child block, or no border, padding, inline content, height, min-height or max-height to separate the margin-bottom of a block from the margin-bottom of its last child, then those margins collapse. The collapsed margin ends up outside the parent.

The ‘rc’ suffix goes back to Unix's grandparent, CTSS.
It had a command-script feature called "runcom". Early
Unixes used ‘rc’ for the name of the operating system's
boot script, as a tribute to CTSS runcom.
