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

/* <length> values */
margin-top: 10px;  /* An absolute length */
margin-top: 1em;   /* relative to the text size */
margin-top: 5%;    /* relative to the nearest block container's width */

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

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