In many ePubs that I own, margins are defined around the text, e.g. in Sarah J. Maas,
Tower of Dawn:
Code:
# css
body {
display: block;
margin: 8px;
}
div.wrapper {
margin: 0em 1.2em 0em 1.2em;
}
# html
<body>
<div class="wrapper">
...
</div>
</body>
In other ePubs (published by large publishing houses like Random House and Harper Collins),
no margins are defined for the body or wrapper and, if viewed in a webbrowser, the text flows from edge to edge of the browser window.
Should or shouldn't I define margins? Why? When?
