Well,basically I gotta say: yes, I want margins to change with the font size.
O.k. I admit, sometimes it ain't so good: for example when it's something like the start of a chapter, I use top margin 5 em, so that there is some space before the chapter title.
However, especially when it comes to "characters per line", I see it different. With my CSS, when a new paragraph starts, it starts with a text intend of 1.5 em. And I removed the empty line between 2 paragraphs, so it really looks like a paper book.
Now let's say, I use a fixed size like for example: text intend of 1.5 centimetres or maybe 5 yards
... you know what I mean. Lets say my textsize is 1em (let's say that would be about 1 centimetre). But now I zoom in. Now, my font is twice as big as before, but the intend stays the same. Let's say I zoom again, and now my font size is 10 times as big as before (unrealistic, but I just want to make it obvious). So now my font size is about 10 cm, while the text intent still is 1.5 cm. The whole thing would look different.
No one knows what the future will bring, that's why I keep all my ebooks in html file with external css files. It is pretty easy to change an external css and convert it with calibre.
