Css Margin-top Example
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;
