Although the headings and links in nav elements allow any [html] phrasing content, app-based reading systems often only support simple text labels. Because these appscreate their own navigation widgets that are not based on HTML rendering, they often cannotretain embedded images and multimedia, MathML, inline styling and other element- andattribute-based rendering instructions. EPUB creators should avoid using these types of elementswhere their absence may lead to usability issues.

EPUB Navigation Documents optionally may include one or more nav elements in addition to the toc, page-list and landmarks nav elements defined above. Such additional nav elements should have an epub:type attribute to provide a machine-readable semantic, and must have a human-readable heading as their first child.
The transforms that act on the XHTML output are where all the work happens. There are varioustransforms, for example, to insert book metadata as a page at the start of the book,to detect chapter headings and automatically create a Table of Contents, to proportionallyadjust font sizes, et cetera. It is important to remember that all the transforms act on theXHTML output by the Input plugin, not on the input file itself. So, for example, if you ask calibreto convert an RTF file to EPUB, it will first be converted to XHTML internally,the various transforms will be applied to the XHTML and then the Output plugin willcreate the EPUB file, automatically generating all metadata, Table of Contents, et cetera.
For example, suppose we want to take a heading and the first paragraph that follows it, and wrap this in a so that we can apply a style to the whole block. We can create a javascript file that includes the following:
Our step-by-step guide teaches you the basics of HTML and how to build your first website. That means how to layout an HTML page, how to add text and images, how to add headings and text formatting, and how to use tables.
Specify a template for the filenames in a chunkedhtml document. In the template, %n will be replaced by the chunk number (padded with leading 0s to 3 digits), %s with the section number of the chunk, %h with the heading text (with formatting removed), %i with the section identifier. For example, %section-%s-%i.html might be resolved to section-1.1-introduction.html. The characters / and \ are not allowed in chunk templates and will be ignored. The default is %s-%i.html.
These rules should, in most cases, allow one to determine the identifier from the heading text. The exception is when several headings have the same text; in this case, the first will get an identifier as described above; the second will get the same identifier with -1 appended; the third with -2; and so on.
If the --section-divs option is specified, then each section will be wrapped in a section (or a div, if html4 was specified), and the identifier will be attached to the enclosing (or ) tag rather than the heading itself. This allows entire sections to be manipulated using JavaScript or treated differently in CSS.
When the header row is omitted, column alignments are determined on the basis of the first line of the table body. So, in the tables above, the columns would be right, left, center, and right aligned, respectively.
The cells of pipe tables cannot contain block elements like paragraphs and lists, and cannot span multiple lines. If any line of the markdown source is longer than the column width (see --columns), then the table will take up the full text width and the cell contents will wrap, with the relative cell widths determined by the number of dashes in the line separating the table header from the table body. (For example ---- would make the first column 3/4 and the second column 1/4 of the full text width.) On the other hand, if no lines are wider than column width, then cell contents will not be wrapped, and the cells will be sized to their contents.
The man page writer extracts a title, man page section number, and other header and footer information from the title line. The title is assumed to be the first word on the title line, which may optionally end with a (single-digit) section number in parentheses. (There should be no space between the title and the parentheses.) Anything after this is assumed to be additional footer and header text. A single pipe character () should be used to separate the footer text from the header text. Thus,
For chapter and section, the HTML filenames will be determined by the header identifiers, e.g., the filename for the first chapter with a chapter title # Introduction will be introduction.html by default. For chapter+number and section+number, the chapter/section numbers will be prepended to the HTML filenames, e.g., 1-introduction.html and 2-1-literature.html. The header identifier is automatically generated from the header text by default,9 and you can manually specify an identifier using the syntax #your-custom-id after the header text, e.g.,
This style is designed for books that use one chapter per page.This means that each chapter is an .Rmd file, and each .Rmd file can contain one chapter.Each file must start with a first-level heading, # Chapter title, and that must be the only first-level heading in the file.
The index.Rmd file is required, and is also your first book chapter. It will be the homepage when you render the book. If you want to include content that should only be included in the HTML version of the book, you may want to include that content conditionally by combining the knitr include chunk option with the knitr::is_html_output() function. See the R Markdown Cookbook for instructions.
That means that you can use most arguments of rmarkdown::html_document, such as toc (whether to show the table of contents), number_sections (whether to number section headings), and so on. Again, check the help page of rmarkdown::html_document to see the full list of possible options. Note that the argument self_contained is hard-coded to FALSE internally, so you cannot change the value of this argument. We have explained the argument split_by in the previous section.
What the default page builder does is to put TOC in the first row, the body in the second row, navigation buttons at the bottom of the body, and concatenate them with the HTML head and foot. Here is a sketch of the HTML source code that may help you understand the output of build_chapter():
As a matter of fact, you can get rid of the Bootstrap style in html_document() if you set the theme option to null, and you are free to apply arbitrary styles to the HTML output using the css option (and possibly the includes option if you want to include arbitrary content in the HTML head/foot). 2ff7e9595c
