position: relative;

The "position: relative" CSS property is used to position an element relative to its normal position. This means that the element will still take up the same space as it normally would, but it can be moved or shifted from its original position using the top, bottom, left, and right properties.

For example, if you have a div that has the "position: relative" property set, and you want to move it 10 pixels to the right, you would use the following CSS:

div {
position: relative;
left: 10px;
}

This would move the div 10 pixels to the right of its original position, while still maintaining its height and width.

One common use for the "position: relative" property is in creating dropdown menus. By setting the parent element to "position: relative" and the dropdown menu to "position: absolute", you can position the dropdown menu relative to the parent element and have it appear exactly where you want it.

Overall, the "position: relative" property is a useful tool for controlling the position and layout of elements on a webpage.
