css padding-top property syntax
Function: Set the top padding (space) of the element.
Description: This attribute sets the width of the padding on the element. Top padding set on inline, non-replaced elements does not affect line height calculations, so if an element has both padding and background, it may visually extend to other lines and possibly overlap other content. . Negative padding values are not allowed.
Note: Negative values are not allowed. All major browsers support the padding-top attribute. The attribute value "inherit" is not supported in any version of Internet Explorer (including IE8).
