It is possible to link to a specific portion of a page.
- headers automatically become html anchors, which can be linked to.
- The <a> tag is not allowed in MediaWiki, so we can't do the <a name="link here">, but we can do the "id" html attribute to almost any existing tag. For example, <div id="what_to_link_to">text</div>.
inside a regular wiki link [[page#anchor_name|shown_up_as]], include the hash sign (#) and the header name or the id tag name as you have written it.
