HTML reader: retain attribute prefixes and avoid duplicates. Previously we stripped attribute prefixes, reading `xml:lang` as `lang` for example. This resulted in two duplicate `lang` attributes when `xml:lang` and `lang` were both used. This commit causes the prefixes to be retained, and also avoids invald duplicate attributes. Closes #6938. 2020-12-11 00:44:10 +01:00			`<nav epub:type="landmarks" id="landmarks" hidden="hidden">`

Add text wrapping to HTML output. Previously the HTML writer was exceptional in not being sensitive to the `--wrap` option. With this change `--wrap` now works for HTML. The default (as with other formats) is automatic wrapping to 72 columns. A new internal module, T.P.Writers.Blaze, exports `layoutMarkup`. This converts a blaze Html structure into a doclayout Doc Text. In addition, we now add a line break between an `img` tag and the associated `figcaption`. Note: Output is never wrapped in `writeHtmlStringForEPUB`. This accords with previous behavior since previously the HTML writer was insensitive to `--wrap` settings. There's no real need to wrap HTML inside a zipped container. Note that the contents of script, textarea, and pre tags are always laid out with the `flush` combinator, so that unwanted spaces won't be introduced if these occur in an indented context in a template. Closes #7764. 2021-12-20 22:44:03 +01:00			`<li><a href="text/title_page.xhtml" class="titlepage">Title`
			`Page</a></li>`
HTML reader: parse attributes on links and images. Closes #6970. 2021-11-24 20:01:21 +01:00			`<li><a href="#nav.xhtml#toc" class="toc">Table of Contents</a></li>`

Improved makeSections so we don't get doubled attributes. Closes #5986. 2019-12-17 20:09:00 +01:00			`<section id="ch001.xhtml#hi" class="level1" data-number="1">`
