Addressable Paragraphs
|
||
|
|
------------------------
|
||
|
|
In converting from .md to .html, images are wrapped in <p> tags.
|
||
|
|
This plugin gives those paragraphs the 'img' class for styling enhancements.
|
||
|
|
In case there is any description immediately following that image, it is wrapped in another paragraph with the 'caption' class.
