The standard on fixed layout book is to use pixel measurement.
Depends on the elements that contain the element you're styling and on what property the percentages are being applied to:
- Font sizes measured in percentages are relative to the previous size, and should be reasonably safe.
- Percentages for things like width or height of an element are relative to the size of the enclosing container. If that enclosing container is not a fixed size, then neither is a percentage of that size. If it is a fixed size, then a percentage of that size should always be the same.
