How to make body use “padding”or“margin” ？

[wangyingowen]

set up a full screen, and my book HTML tag set background, for example, <html... class= "background-img-repeat" >... /body>. body set marin:50px.
The content of the body is covered with the screen, and why? android&&readium 1

First of all, what happens when you open your HTML file in standard web browser, and expand the browser window to full screen? Is your content fully stretched too?

Secondly, the Readium layout/rendering process removes HTML body margin so that the pagination engine can deliver consistent results with respect to blank spacing on the outer edges. Maybe this is what you are getting to? Have you tried using min-max width CSS to set appropriate dimensions for your content? Again, first it would be preferable to test in regular web browsers, then see how things look in Readium. You could use the Readium cloud reader to save you time, compared with launching the Andoid app.
