But margin has a famous quirk called \u003Cstrong>margin collapse\u003C\u002Fstrong>, where vertical margins combine instead of adding up.

The browser splits the free horizontal space equally between the left and right margins. It does not work on inline elements, and \u003Ccode>margin: auto\u003C\u002Fcode> does not center vertically in normal block flow. In Flexbox and Grid, auto margins absorb free space in both directions, for example \u003Ccode>margin-left: auto\u003C\u002Fcode> pushes a nav button to the far end of the row.\u003C\u002Fp>\u003Ch3 id=\"negative-margins\">Negative Margins\u003C\u002Fh3>\u003Cp>Margins can be negative.

Another popular pattern is the stack (also called the lobotomized owl selector): \u003Ccode>.stack > * + * { margin-block-start: 1rem; }\u003C\u002Fcode>. It adds space only between siblings, so there is no extra space at the start or end. Utility frameworks such as Tailwind CSS use similar ideas with space-y and gap utilities. The newer \u003Ccode>margin-trim\u003C\u002Fcode> property is designed to trim margins at container edges, but browser support is still limited, so check before relying on it.\u003C\u002Fp>\u003Ch3 id=\"margin-vs-padding-quick-decision-guide\">Margin vs Padding: Quick Decision Guide\u003C\u002Fh3>\u003Cul>\u003Cli>Space between two elements: use margin (or gap).\u003C\u002Fli>\u003Cli>Space inside an element between content and border: use padding.\u003C\u002Fli>\u003Cli>Background color behind the space: use padding, because margin is always transparent.\u003C\u002Fli>\u003C\u002Ful>\u003Ch3 id=\"common-mistakes\">Common Mistakes\u003C\u002Fh3>\u003Cul>\u003Cli>Expecting 40px plus 30px to equal 70px between siblings.\u003C\u002Fli>\u003Cli>Adding margin-top to the first child and wondering why the whole parent moves.\u003C\u002Fli>\u003Cli>Using negative margins for layout when Grid or Flexbox is cleaner.\u003C\u002Fli>\u003Cli>Using margin on inline elements to create vertical space.\u003C\u002Fli>\u003Cli>Setting both margin-top and margin-bottom on every element, creating confusing collapse behaviour.\u003C\u002Fli>\u003C\u002Ful>\u003Ch3 id=\"frequently-asked-questions\">Frequently Asked Questions\u003C\u002Fh3>\u003Ch4 id=\"why-is-my-margin-top-not-working\">Why is my margin-top not working?\u003C\u002Fh4>\u003Cp>Common causes: the element is inline, the margin is collapsing with its parent, or another rule overrides it.
