Task 2604: Consolidate Banner Designs & Placements - #2636
Conversation
Replaces the placeholder on the v3 library subpage with the designed empty state: headline, a sentence naming the library and versions, a "Switch to ..." CTA and the bookshelf illustration, built on the shared library hero. - Add optional cta_label/cta_url/cta_icon_name to _hero_library.html, rendered through the existing hero button component - Add a hero--library-unavailable variant: page surface instead of the accent background, Figma's 32px content rhythm, bottom-flush illustration blended into the surface, and a min-height so the longer copy can't overflow the version alert in the tablet band - Build the sentence and CTA in the view, since both branch on data: a library with no releases has no "first release" clause and nowhere to switch to, and a library dropped from Boost points at its last release rather than latest - Skip the subpage card context entirely when the version is missing
Drop the parts that restate what the declarations already show and keep the reasons that are not visible from the code: the --header-height resolution trap, the stacking context that closes the blending group, and why the block's fixed height becomes a floor.
The first-release lookup only feeds the 'elif' sentence, so evaluate it there instead of unconditionally. Its filters were also a copy of the newest-release lookup's, so both now derive from one queryset.
…state master and develop carry no version number, so the numeric comparison placed them before the library's first release and the page offered the 'first release' sentence for a library that had left Boost. They are branch heads, so they sort after every release instead. Also word them as 'the develop branch' rather than 'Boost develop'.
The alert sat in the hero's column, so showing or dismissing it moved everything below by its height plus the section gap. It now overlays the slack the hero already leaves under the header, and .hero__block keeps its own clearance, so the hero is the same height either way. Below 767px there is no such slack and the message can wrap to three lines, so the alert stays in flow there rather than cover the heading.

Resolve the CSS lint errors.
The declaration-empty-line-before rule requires blank lines before the affected declarations in this block and before width in .v3-container. Add the missing blank lines in both locations so the lint check passes.

Set a non-assertive role for the version alert.
This include renders the persistent version alert on initial page load. templates/v3/includes/_version_alert.html:18 does not pass a role, so _banner.html assigns role="alert". Update that include to pass role="region" and an aria_label, such as "Version notice". This prevents an assertive announcement on each navigation.

Nice work on this!
A couple issues I noticed on testing: the banners overlap rather than pushing down content, so the first banner overlaps the page heading below 768px and the second banner overlaps it at any width. I didn't see a multiple banner use case design in Figma. Question for PM/Design?
Also, the issue mentions that we need 1 banner at a time and a compact version for each color, which I don't see implemented here yet.

Heya, all good from my end, thanks @julhoang !
One thing to notice is that in some pages the spacing is a little weird because of the overlapping, where they don't have a big enough room to accommodate the banner.
I think this is outside of the scope of this ticket though, better to create a P2 ticket to address these small spacings if necessary @henryajisegiri .

Issue: #2604
Summary & Context
Gives V3 a single notification slot under the navbar: Django messages, the version alert and the scheduled-deletion notice all render as the same
_banner.htmlcomponent, stacked in one place instead of three separately-positioned banners. Adds success and error variants, splits dismissal by severity, and consolidates the page-shell padding and sticky-footer rules the slot depends on.Changes
System banner slot
v3/includes/_messages.html— renders each queued message as a banner insidebase.html's messages slot, positioned under the navbar. Standing notices first (scheduled deletion, then version alert), flash messages after, newest last.base.html: V3 uses the new slot, legacy keepspartials/messages.htmluntouched.v3/includes/_banner.htmlwith optional inputs for a variant, a CSS-only dismiss, an inline POST action and the ARIA role — each documented in its comment block..header's own padding and height, including its switch at 990px.banner_variantsinV3ComponentDemoView+ the Alert Banner section).Dismissal without JavaScript
--banner-fgcustom property, so a variant only overrides the surface and, where contrast needs it, that value.:has(:checked)instead of Alpine, so the ✕ works with JS disabled. The auto-fade was already a CSS animation.hideMessage()inbase.html—#messagesonly exists on legacy pages now, and the call ran unconditionally.Move the deletion notice and version alert into the slot
heros.css, and the version-alert variablesrelease_detail.htmlforwarded into the hero just to render it.{% block messages %}override inuser_profile_edit.htmlso that page uses the shared slot.Suppress V3-redundant account messages
v3flag is on, matched on message template rather than text: signed in, signed out, and confirmation-email-sent. Each duplicates what the page the user lands on already says. Legacy keeps all three.Create-post flow
V3AllTypesCreateViewcalled its parent'sdispatchexplicitly and throughsuper(), running the whole view twice and queueing every message twice. The parent guard is already next in the MRO, so the override is deleted rather than reworked. Successful posts escaped it only because they return a 302.Page shell and footer consolidation
--v3-shell-guttertoken:.v3-containersets it, the full-bleed shells (homepage, community, release, library subpage, auth) leave it at 0, and the slot cancels it so the banner is the same width on every page..v3-containernow pads by the token instead of--space-medium.body.v3; the auth page keeps its override, re-prefixed so it still outweighs the shared rule.--v3-header-height/--v3-header-footprintonbody.v3soheader.cssandbanner.cssstop recomputing the navbar's size separately. They had drifted to different numbers becausevar(--header-height)is the legacy 41px outside.header; the page spacer now uses the header's real footprint..card-masonry-top > div { min-width: 0 }..v3-containerpages, because it now uses the header's real footprint instead of the legacy 41px plus the wrong padding token: 65px → 64px on desktop, 65px → 72px on tablet, 57px → 72px on mobile. The new numbers clear the navbar (the old mobile one was short), but it is a visible shift at those widths.Peer-Testing Guidelines
