left

The left CSS property specifies part of the position of positioned elements.
 
For absolutely positioned elements (those with position: absolute or position: fixed), it specifies the distance between the left margin edge of the element and the left edge of its containing block.

Example

<!DOCTYPE html>
<html>
    <head>
        <style>
            #example_1 {
                width: 200px;
                height: 200px;
                position: absolute;
                left: 200px;
                top: 20px;
                background-color: #D8F5FF;
            }
        </style>
    </head>
    <body>
        <div id="example_1">
            <p>
                The only containing element for this 
				div is the main window, so it positions 
				itself in relation to it.
            </p>
        </div>
    </body>
</html>
