Spacing and fontsize in floats

[Detlev Humann]

Hi! I´ve got many floats in my document like this:   caption figure/table "my explanation"   I`d like to change the space between figure/table and "my explanation". Is there a way to do it automatically for all floats or do I have to change it manually in every float?   Can I have a special fontsize for "my explanation"? In scientific texts it is usual to have a smaller fontsize (or italic) for explanations or references under tables/figures. Is there a way to change the fontsize of "my explanation" for all floats or do I have to change it in each float by myself?   Thanks in advance Detlev
