margin-top

The margin-top CSS property sets the margin area on the top of an element. A positive value places it farther from its neighbors, while a negative value places it closer.

This property has no effect on non-replaced inline elements, such as <span> or <code>.

margin-top: 10px;  /* An absolute length */
margin-top: 1em;   /* relative to the text size */

/* Keyword values */
margin-top: auto;

/* Global values */
margin-top: inherit;
margin-top: initial;
