css top attribute syntax
Function:The top attribute specifies the top edge of the element. This property defines the offset between the top margin boundary of a positioned element and the top boundary of its containing block.
Description: For static elements, it is auto; for length values, it is the corresponding absolute length; for percentage values, it is the specified value; otherwise, it is auto. For relative definition elements, if top and bottom are both auto, their calculated values are both 0; if one of them is auto, the opposite of the other value is taken; if neither is auto, bottom will be the opposite of the top value. Opposite number.
Note: All major browsers support the top attribute. The attribute value "inherit" is not supported in any version of Internet Explorer (including IE8).
