The right margin of a paragraph in Scrivener’s editor isn’t a “from right side of the page” distance, but rather a “from left side of the page” distance for starters. Both the left and the right margins are related to the left side of the “page”.
You have to add the style in the “style” panel of your compile format (using the + sign I circled here : )
I am pretty positive they can. By doing what we just did.
What do you mean ?
To have a different indent for the right than for the left, you may be right. It has to be done in Sigil or something like that. I never really messed around with that. I like my blockquotes centered.
But I am positive that it can be done. In Scrivener ? Maybe not.
But an epub supports it.
I remember pretty well experimenting with it in Sigil.
That is because you checked those options.
The text is not actually truly centered.
It just keeps its relative position to the invisible edge of the editor.
You most likely have the first two checked. (Which is perfectly fine.)
Do the test the other way around :
Make your editor very narrow. You’ll see.
There is no page in Scrivener.
Thus both margins being relative to the left side.
The non existent “page” starts somewhere, but ends nowhere… sort of speak. It has a top and a left side, but neither a bottom or a right side.
But don’t worry about it : after doing what I made you do, the text will be centered in the compiled output.
