![]() In this way it is more like an inline TOC in a book since it is an XHTML document. ![]() It has a human- and machine-readable grammar for publication-wide navigation information and is based on the HTML5 nav element. An internal navigation syntax is defined for ePub 3. Content switching was introduced in OPS 2 but is now simplified.Ī Navigation document is a required element in ePub 3.Semantic Inflection - headings and the like have no fixed meaning global meaning but depend on where in the file they appear.Not all of SVG is supported and the constructions must be XML compliant. They no longer have to be inside an XHTML document. SVG documents can now appear in the spine.Note that HTML5 allows constructions that are not XHTML ( XML) compliant. DTBook is no longer supported as an option for ePub. HTML5 has been adopted as the XHTML format.A new properties entry allows defining publication resources. There is a new link entry that can be used to reference external meta data sources. The metadata elements have been expanded to permit descriptions to be targeted at specific portions of a document as well as the whole document. The dcterms:modified has been added to provide a solution for consistent publication identifiers. The version 2.01 standard for OPF remains basically intact with a few additions. manifest.xml A manifest of container contents as allowed by Open Document Format.rights.xml Used to store information about digital rights.metadata.xml Used to store metadata about the container.(This file is required if font obfuscation is used.) encryption.xml Contains information about the encryption of Publication resources.signatures.xml Contains digital signatures for various assets.container.xml Identifies the file that is the point of entry for each embedded Publication.The following items are specified in the OCF. In 2.0 the access outside with links was not defined but this omission has been addressed in 3.0 to limit the access to specific cases outside the zip file. A fourth document is concerned with Media Overlays and is a new feature of ePub version 3.Īn ePub file continues to be a self contained document with everything contained in one zip file. This now includes the old NCX specifications which are no longer used. The OCF remains the same and the OPS received the most changes to become the ePub Content Documents. The OPF becomes the ePub Publications standard. The new 3.0 standard has 4 defining documents with new names. The OPS referenced a DAISY standard for the NCX file. !apptooltip would also work).In version 2.01 there were three defining documents, the OPF (Open Packaging Format), the OCF (Open Container Format), and the OPS (Open Publications Structure). You could use any text except 'important' after the exclamation mark (e.g. It isn't recognised by the browsers, so they ignore the entire property declaration. The !rhstyle text is the hack that means it doesn't display in browsers.I figured some sort of background colour would be stand out. You can use whatever value you want as long as it meets the ID guidelines - there's a couple of characters you can't use I think space is a banned one. But if you decided to always use a span, you could write it as span#apptooltip. I haven't specified a tag, so it will match where ever you use the id. # apptooltip indicates you're targeting a tag with an ID attribute that has a value of "apptooltip".Similar to the data-xx, you can't see that it's set in the RH interface, but you could apply a hack so the style displays in RH but not in browser (As far as I can tell. The id attribute can go on any tag as far as I'm aware, so you could put it on a p, or wrap what you need in a span or a div, depending on your needs. But you'd have to ask web developers about it. Unless it's more extensible that I think. Thinking about it again, I think it's not going to do what you want, as you'd need to put the content in the data-xx attribute.
