The sensitive text feature was implemented with <label> and hidden
checkbox <input> elements. There were two issues with this
implementation:
1. The user couldn't navigate to the "show/hide more" button using
keyboard.
2. The label indicates two actions at the same time ("show/hide more"),
making it unclear what the function of the checkbox was and what the
current show/collapse state was.
As it is generally preferrable to use built-in HTML elements for the
best semantic, this commit moves to use the <details> and <summary>
elements for the sensitive text feature. The browser will open/collapse
the content in <details> automatically when the user clicks on the
<summary>, and keyboard navigation support is built-in.
This commit also changes the button to display "show more" or "show
less" depending on the state for visual clarity. This button is hidden
from the accessibility tree using `aria-label="false"`, as the <details>
element already exposes its state to the tree and we want to avoid
duplicated information.
A few caveats:
* The "show/hide sensitive content" button for sensitive attachments
hasn't been changed yet as I'd like to get more feedback about the new
implementation.
* As the summary/content warning text itself is also part of the
<summary> tag, the user can now also click on them to toggle the
visibility of the sensitive text. This may not be desirable as the
current interface does not make it clear that this could happen; the
user may try to select some text from the summary and be surprised
by the sensitive text being expanded. One way to improve this would
be to add an event listener to the summary text and call
`preventDefault`, but this would introduce JavaScript code.
I'd like to customize my instance's theme beyond what's possible with
_theme.scss. This patch would allow me to do that, and keep my changes
self-contained in data/ without maintaining a local patchset over
app/templates/.
For utils.html, I've also added scoped blocks around the body of every
macro. This allows the macros to be overridden individually in
data/templates/utils.html, without copying the whole file. For example,
to only override the display of a specific actor's name/icon:
{% extends "app/utils.html" %}
{% block display_actor %}
{% if actor.ap_id == "https://me.example.com" %}
<!-- custom actor display -->
{% else %}
{{ super() }}
{% endif %}
{% endblock %}
