(Sorry, I'm not familiar with it and click the wrong button..) Hi David, Thanks for the comments! My initial plan is to implement the following items as the first step:
- Normal: When applied to an inline box, specifies that the over/under content edges coincide with the text-over/text-under baselines regardless of text-edge (which nonetheless still affects line box sizing). - End, start, and both: For inline boxes: treat all as if text-edge is "text" (it should be "trims the block-end side of the box to match its content edge to the metric specified by text-edge (treating leading as text)." I'm not sure if I would encounter any problems after starting with this status. If anyone foresee the potential risks, I'd appreciate it!
