Set it to "height: 10cm", or similar, instead, and it should work as expected (but not as wanted).
This, of course, unless I'm mistaken due to ignorance or misunderstanding of the specs  |
You're right. What I said wasn't quite complete. You'll also need to set sizes for the
body and
html tags and clear out their margins/padding.
It might also be worth using min-height instead of height just in case A. your content ends up on a device that doesn't support SVG, B. your fallback content is used, and C. it is taller than a screenful.
In other words:
Code:
<html style="min-height: 100%; width: 100%; padding: 0; margin: 0; border-width: 0;">
<body style="min-height: 100%; width: 100%; padding: 0; margin: 0;border-width: 0;">
<div style="min-height: 100%; width: 100%; padding: 0; margin: 0; border-width: 0;">
<object data="..." preserveAspectRatio="..." viewBox="0 0 100% 100%">
Optional non-SVG fallback HTML or image here
</object>
</div>
</body>
</html>
Because the outer
html tag has no containing element, per section 10.1 of the CSS 2.1 spec (#1 in the numbered list), a
width or
min-height value of
100% causes it to fill the viewport (if it isn't already larger than the viewport) or the page, depending on whether you're talking about the web or paged media. In the case of an EPUB reader, I'd expect that distinction to be moot.
In an ideal world, we would all just use the new CSS3 viewport-relative lengths (
vw and
vh), but I suspect it will be many years before you can count on that unit being supported broadly enough to be useful.
