While the default behavior is for Markdown to not alter raw HTML, as this extension is parsing the content of raw HTML elements, it will do some normalization of the tags of block-level elements. For example, a block element may contain either blockĮlements or span elements as children and each element will be parsed using the specified behavior. Parent, the the child element’s behavior is observed. However, if the value of an element’s markdown attribute is the same as, or more restrictive than, its For example, a block element nested within a span element will be parsed using the spanīehavior. When the value of an element’s markdown attribute is more permissive that its parent, then the parent’s stricterīehavior is enforced. Ignored, including child elements with markdown attributes. For any block-level element which does not have a markdown attribute, everything inside that element is When nesting multiple levels of raw HTML elements, a markdown attribute must be defined for each block-levelĮlement. All other raw HTML tags are treated as span-level tags and are not affected by this The following tags are always ignored, regardless of any markdown attribute: canvas, math, option, pre, Only inline syntax will be rendered, such as links, strong, emphasis, etc. The content of a span element is not parsed into block-level content. Of the element so long as it is one of the block or span tags. When the markdown attribute is set to "span", then the parser will force the span behavior on the contents Reserved for advanced users who understand the HTML specification and how browsers parse and render HTML. Explicitly setting markdown="block" should be Recommended to use the default behavior of markdown="1". Any inline syntax within those elements is processed as well.įorcing elements to be parsed as block elements when they are not by default could result in invalid HTML.įor example, one could force a element to be nested within another element. Paragraphs, headers, lists, blockquotes, etc. The content of a block element is parsed into block-level content. The element so long as it is one of the block or span tags. When the markdown attribute is set to "block", then the parser will force the block behavior on the contents of The following tags have the span behavior by default: address, dd, dt, h, legend, li, p, td, Iframe, main, map, menu, nav, noscript, object, ol, output, progress, section, table, The following tags have the block behavior by default: article, aside, blockquote, body, colgroup,ĭetails, div, dl, fieldset, figcaption, figure, footer, form, group, header, hgroup, hr, When the markdown attribute is set to "1", then the parser will use the default behavior for that specific tag. Whereas the "span" and "block" values assigned to the markdownĪttribute refer to the Markdown parser’s behavior. The expressions “block-level” and “span-level” as used in this document refer to an element’s designationĪccording to the HTML specification.
