Can I define a class name on paragraph using Markdown  If so  how

User · Answer

Markdown should have this capability  but it doesn t  Instead  you re stuck with language-specific Markdown supersets   PHP  Markdown Extra Ruby  Kramdown  Maruku  But if you need to abide by true Markdown syntax  you re stuck with inserting raw HTML  which is less ideal

It should also be mentioned that  lt span gt  tags allow inside them -- block-level items negate MD natively inside them unless you configure them not to do so  but in-line styles natively allow MD within them  As such  I often do something akin to     This is a superfluous paragraph thing    lt span class  class-red  gt And thus I delve into my topic  Lorem ipsum lollipop bubblegum  lt  span gt   And thus with that I conclude    I am not 100  sure if this is universal but seems to be the case in all MD editors I ve used

Raw HTML is actually perfectly valid in markdown   For instance   Normal  markdown  paragraph    lt p class  myclass  gt This paragraph has a class  myclass  lt  p gt    Just make sure the HTML is not inside a code block

As mentioned above markdown itself leaves you hanging on this   However  depending on the implementation there are some workarounds   At least one version of MD considers  lt div gt  to be a block level tag but  lt DIV gt  is just text   All broswers however are case insensitive   This allows you to keep the syntax simplicity of MD  at the cost of adding div container tags   So the following is a workaround    lt DIV class foo gt     Paragraphs here inherit class foo from above    lt  div gt    The downside of this is that the output code has  lt p gt  tags wrapping the  lt div gt  lines  both of them  the first because it s not  and the second because it doesn t match   No browser fusses about this that I ve found  but the code won t validate   MD tends to put in spare  lt p gt  tags anyway   Several versions of markdown implement the convention  lt tag markdown  1  gt  in which case MD will do the normal processing inside the tag   The above example becomes    lt div markdown  1  class foo gt     Paragraphs here inherit class foo from above    lt  div gt    The current version of Fletcher s MultiMarkdown allows attributes to follow the link if using referenced links

If you just need a selector for Javascript purposes  like I did   you might just want to use a href attribute instead of a class or id   Just do this    lt a href   foo  gt Link lt  a gt    Markdown will not ignore or remove the href attribute like it does with classes and ids   So in your Javascript or jQuery you can then do      a href   foo     click function event             do your thing          event preventDefault          At least this works in my version of Markdown
