left style property

Browser support:
Specifies or returns the left coordinate of a positioned element.
A positioned element is an element whose position property is set to relative, absolute or fixed. The value of the left property specifies the left position of the element including the padding, scrollbar, border and the margin.
Use the left, top, right and bottom properties to specify the position for elements. You can set the size of an element with the width and height properties.
The type of the left property is string. You can set or retrieve the value of the left property as an integer with the pixelLeft property. It contains the value in pixels. If you want to get or set the left property as a floating-point number that specifies the value in the current unit type of the left property, use the posLeft property.
The properties mentioned above can be used to access style settings. If you need the left position of a rendered element, you can use the clientLeft, offsetLeft and scrollLeft properties and the getBoundingClientRect method.
