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 */
margin-top: anchor-size(height);
margin-top: calc(anchor-size(--my-anchor self-inline, 25px) / 4);

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

/* Global values */
margin-top: inherit;
margin-top: initial;
margin-top: revert;
margin-top: revert-layer;
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.
  - For anchor-positioned elements, the anchor-size() function resolves to a <length> value relative to the associated anchor element’s width or height (see Setting element margin based on anchor size).
<percentage>
- : The size of the margin as a percentage, relative to the inline size (width in a horizontal language, defined by writing-mode) of the containing block.
auto
- : The browser selects a suitable value to use. See margin.
