For challenges like implementing new skins which are making use of HTML5 sectioning elements `main`, `footer` or `nav` and for interoperability between skins code should limited to only ids and classes and remove `div` mentions.
== Proposal
[] [[ https://codesearch.wmflabs.org/search/?q=div%23content&i=nope&files=&repos= | div#content ]] becomes `.mw-body`, on some exceptions in order to prevent unforeseeable breakage `#content.mw-body`,

| Current `.mw-body` selector, 2020-03-23 | core | Vector | MinervaNeue | Monobook | Timeless | Modern | CologneBlue
| | -- | -- | -- | -- | -- | -- | --
| `div#content` | | | | | | | |
| `#content` or id equiv | | | | | | `#mw_contentholder` | `#article`
| `.mw-body` | {icon check color=green} | {icon check color=green} | {icon check color=green} | {icon check color=green} | {icon check color=green} | | |
Note, CologneBlue also features `#content`, but it's used on parent element of `#article.mw-body`
Note, MinervaNeue uses `.mw-body > .content` over `#bodyContent`
[x] [[ https://codesearch.wmflabs.org/search/?q=div.portal&i=nope&files=&repos= | div.portal ]] becomes `.portal`
[ ] [[ https://codesearch.wmflabs.org/search/?q=div%23footer&i=nope&files=&repos= | div#footer ]] becomes `.mw-footer`, in rare occasions remains only `#footer`
