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>.

Syntax

/* <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;

The margin-top property is specified as the keyword auto, or a <length>, or a <percentage>. Its value can be positive, zero, or negative.

Values

<length>: The size of the margin as a fixed value.
<percentage>: The size of the margin as a percentage, relative to the width of the containing block.
auto: The browser selects a suitable value to use. See margin.
