The fastest ship in its class, its huge meeting room with its 360 degrees
of viewports give it a light and welcoming feel that the Normandy and its enclosed spaces lacked.
This means we add a margin of 50 %

The result of this mapping is typically the bounds
of the Viewport.
If you have to keep worrying about what might be happening beyond the edges
of your viewport, you're going to get stressed and your focus will be shattered.

iBooks for iOS has a bug

While the CSS display property can be used to control the visual rendering

Refer to rendition:

of the rendering.
When synthetic spreads are used in the context
of XHTML and SVG Content Documents, the dimensions given via
viewport / viewBox metadata represents the size
of one page in the spread.
Reading Systems must clip XHTML content to the ICB dimensions declared in the
viewport meta tag, and therefore content positioned outside
of the initial containing block is not going to be visible.
Note that the presence
of rendition: page - spread - center does not change the
viewport dimensions; in particular it does not indicate that a
viewport with the size
of the whole spread should be created.
This document defines one additional property, rendition: page - spread - center, which indicates that the synthetic spread mode should be overridden such that instead
of two adjacent
viewports, a single
viewport must be used, and positioned at the center
of the screen.
Use
of the rendition:
viewport property [Packages 3.1] is now deprecated.
When rendering Fixed - Layout Documents, the default intent is that the Content Display Area should occupy as much

Reading Systems must clip XHTML content to the initial containing block (ICB) dimensions declared in the
viewport meta tag — content positioned outside
of the initial containing block will not be visible.
The primary change made was to introduce a new property to allow the dimensions
of the page to be specified in the package document: rendition:
viewport.
By default, when you set an XHTML content document as pre-paginated, the dimensions
of the page are obtained from the
viewport property in the head
of the document:
While this is still required to be set, the rendition:
viewport property reduces the work
of the reading system by providing the information up front (i.e., without having to parse the XHTML document to get the dimensions before rendering it).
Some people were confused by the use
of media queries in the style sheet examples, taking them as also setting the
viewport.
The default pagination
of these publications by Reading Systems is not static, since it changes depending on the
viewport size and user's font settings.
The presence
of rendition: page - spread - center does not change the

By providing one

Furthermore, this specification allows Authors to define a condensed entry designed specifically for ease
of reading in a lookup
viewport [ContentDocs301]; refer to Condensed and Detailed Entries for details.
While precise characteristics
of the lookup
viewport will depend on the Reading System and user preferences, Authors may assume that the lookup
viewport is functionally or physically limited when compared to the reading
viewport.
A Reading System conforming to this specification should support rendering
of condensed - entry during lookup as described in Interpreting Condensed Entry and Detailed Entry Markup and Rendering in
Viewports.
Moreover, in consideration
of the length
of many dictionary entries as well as variation in the size
of the user's lookup
viewport, dictionary markup allows Authors to tailor an entry specifically for rendering in constrained
viewports.
There is coding on the cover page that maximizes the cover image to the edge

The vision
