"Left center" is not a single, valid keyword for the background-position property in CSS. The valid keywords are individual positions like "left," "center," "right," "top," "bottom," or combinations of these, but each part of the combination must be from a different axis (horizontal and vertical). "Left center" combines two different types of alignment (horizontal and vertical) into one, which is a valid syntax, but it is not considered a single keyword.
