An expression like change line-height:1.* into line-height:1.1 was perfect. in the beginning Sigil worked the same with wildcards, but they both change to regex and I don't understand them, I am to much in the wildcards as it works from dos 3 til now.
But both thanks, I gonna experience with it.
The only problem you will have is that chapternames will be changed in heights to (not if 2 and higher ) but I am a bit in the right direction.
As said, Google is not my friend because I am not good with keywords and english is not my native language ( had only one year lessons
)
