Greetings! On the line height issue - allowing zero as a value, see in part:
http://www.w3.org/TR/CSS2/visuren.html More specifically: 9.4.2 Inline formatting contexts Where you will read: Line boxes are created as needed to hold inline-level content within an inline formatting context. Line boxes that contain no text, no preserved white space, no inline elements with non-zero margins, padding, or borders, and no other in-flow content (such as images, inline blocks or inline tables), and do not end with a preserved newline must be treated as zero-height line boxes for the purposes of determining the positions of any elements inside of them, and must be treated as not existing for any other purpose. Also see: 10.8.1 Leading and half-leading For definition of line-height, which reads in part: On a block container element whose content is composed of inline-level elements, 'line-height' specifies the minimal height of line boxes within the element. The minimum height consists of a minimum height above the baseline and a minimum depth below it, exactly as if each line box starts with a zero-width inline box with the element's font and line height properties. We call that imaginary box a strut. (The name is inspired by TeX.). So it really is true that zero is a legitimate value for line-height. Hope everyone is at the start of a great week!
