Closes#17245 and #17253
When the user selects a doc item in the side nav:
1) expand folder(s) leading to the selected doc item
2) on a wide display, keep other already expanded folders open
3) on narrow (mobile) display, collapse other expanded folders
Used to do (3) when wide. Issue #17245 asks for (2).
That logic was bypassed for selected node when we allowed headers to have content
because that unintentionally expanded the header’s folder when selected.
Because the selected node is no longer a header with content, removing this exclusion
also means that folders are expanded/collapsed with above logic even for API pages.
Rather than hard coding excludes into the dgeni config,
use the fact that we are already ignoring the boilerplate
and generated files via the .gitignore file.
Previously, the main content would always leave a 18% margin on the right to be
occupied by the ToC (even if there was no ToC).
This commit lets the main content expand to the right to occupy all the
available space when there is no ToC.
Fixes#17205Fixes#17270
Previously, when scrolling the ToC and reaching the top/bottom, further
mousewheel events would result in scrolling the window (and thus the main
content). This is standard browser behavior. In the case of the ToC though, the
`ScrollSpy` would detect scrolling in the main content and scroll the active ToC
to entry into view, thus resetting the scroll position of the ToC.
Reproduction:
1. Open `~/guide/template-syntax`.
2. Start scrolling through the long ToC.
3. Try to go to the bottom of the ToC.
4. Once you reach the bottom, the main content starts scrolling down.
5. The first section ("HTML in templates") becomes "active", so the ToC is
scrolled back up to make its corresponding entry visible.
6. Go back to step 2.
This commit improves the UX, by not allowing the main content to scroll when the
cursor is ovr the ToC and the user has scrolled all the way to the top/bottom of
it.
When navigating from a page with open SideNav to a page without closed SideNav,
the main content area animates from a non-zero left margin to zero left margin.
Additionally, the top-bar on the homepage is transparent, which allows the white
background behind the main content to be seen while the left margin is animated
to zero, making it appear as if something (e.g. the SideNav covers the top-bar).
This commit works around this issue, by not making the top-bar transparent
immediately when navigating to the homepage, but animating it from its blue
color to transparent with a delay.
Fixes#17248
An ellipsis was used to separate the most relevant search
results from the alphabetic list. The separator was confusing
because it was not clear what it represented.
This has been removed and the most relevant results are now
indicated by styling with a more bold font and a bit of whitespace
between them and the rest of the results.
To keep things consistent, if there are fewer than 5 results all the
results are now displayed as priorityPages.
Closes#17233
In the marketing pages we do not want to show heading anchors on hover.
Previously, this was achieved by using div rather than heading elements.
Now we can use semantically accurate headings while hiding the anchor.
Closes#17244Closes#17264
Previously, the top-bar's height wasn't taken into account when scrolling an
element into view. As a result, the element would be hidden behind the top-bar.
Taking the top-bar height into account was not necessary before #17155, because
the top-bar was not fixed (i.e. it scrolled away).
This commit fixes the scrolling behavior by accounting for the top-bar's height
when scrolling an element into view.
(This partially reverts #17102.)
