This hierarchy is now going to document built-in modules, which mostly
contain functions but can also contain mixins and may potentially
contain variables in the future.
These used to redirect from /documentation/, but we tweaked the way
URLs work and now they redirect from /documentation. Making them
absolute avoids even the potential for that breakage.
This renders the tabs and all the jQuery classes server-side, so that
the code examples are rendered correctly on the page's first load
rather than waiting for the JavaScript to activate. This also has a
side effect of making them look correct with JavaScript disabled.
This also adds a little additional styling in the noscript stylesheet
to make code examples look better on a narrow viewport with JavaScript
disabled.
Tables of contents are now statically rendered in their appropriately
open/closed states, rather than updated via JavaScript, so they render
correctly on the first page load. In order to make the "page sections"
table still usable without JS, this adds a stylesheet in a <noscript>
tag that forces the sections into an open state.
* Make the font smaller to make them less prominent and help visually
associate the callout with the list.
* Decrease the top margin to more clearly associate them with their
preceding header.
* Lighten the callout background when in another callout to make it
more visible.
* Animate the expand button.
