| Usage: | ||
| {% include anchor_headings.html html=content %} | ||
|
|
||
| Parameters: | ||
| * html (string) - the HTML of compiled markdown generated by kramdown in Jekyll | ||
|
|
||
| Optional Parameters: | ||
| * beforeHeading (bool) : false - Set to true if the anchor should be placed _before_ the heading's content | ||
| * anchorAttrs (string) : '' - Any custom HTML attributes that will be added to the `<a>` tag; you may NOT use `href`, `class` or `title` | ||
| * anchorBody (string) : '' - The content that will be placed inside the anchor; the `%heading%` placeholder is available | ||
| * anchorClass (string) : '' - The class(es) that will be used for each anchor. Separate multiple classes with a space | ||
| * anchorTitle (string) : '' - The `title` attribute that will be used for anchors | ||
| * h_min (int) : 1 - The minimum header level to build an anchor for; any header lower than this value will be ignored | ||
| * h_max (int) : 6 - The maximum header level to build an anchor for; any header greater than this value will be ignored | ||
| * bodyPrefix (string) : '' - Anything that should be inserted inside of the heading tag _before_ its anchor and content | ||
| * bodySuffix (string) : '' - Anything that should be inserted inside of the heading tag _after_ its anchor and content | ||
|
