* Desktop Mode — Chromeless Overrides. |
| 3 |
* |
| 4 |
* CSS adjustments for legacy admin pages rendered inside desktop mode |
| 5 |
* iframes (chromeless mode). All rules are scoped to .desktop-mode-chromeless |
| 6 |
* so they never affect the classic admin or the desktop shell. |
| 7 |
* |
| 8 |
* Plugin and theme developers: to add your own chromeless overrides, |
| 9 |
* enqueue a stylesheet on the 'desktop_mode_chromeless_styles' action. |
| 10 |
* Your CSS just needs to target .desktop-mode-chromeless as the body class. |
| 11 |
* |
| 12 |
* Example: |
| 13 |
* add_action( 'desktop_mode_chromeless_styles', function() { |
| 14 |
* wp_enqueue_style( 'my-plugin-chromeless', plugin_dir_url( __FILE__ ) . 'chromeless.css' ); |
| 15 |
* } ); |

| 37 |

* WooCommerce sidebar-reservation override. |
| 66 |
* |
| 67 |
* `.woocommerce-layout__header` is a `position: fixed` bar WC |
| 68 |
* mounts on every wc-admin and wc-embedded page. Its width is |
| 69 |
* compiled from the SCSS source (header/style.scss) as a literal: |
| 70 |
* |
| 71 |
* position: fixed; |
| 72 |
* top: 32px; // $adminbar-height |
| 73 |
* width: calc(100% - 160px); // reserves classic sidebar |
| 74 |
* z-index: 1001; |
| 75 |
* |
| 76 |
* The 160px subtraction is the classic admin menu width — WC bakes |
| 77 |
* it in at build time so the header doesn't overlap the sidebar |
| 78 |
* in standard admin. Inside chromeless we hide the sidebar, but |
| 79 |
* the header keeps the reservation — so the header ends 160px |
| 80 |
* short of the iframe right edge, and `.woocommerce-layout__activity-panel-wrapper` |
| 81 |
* (`position: absolute; right: 0; top: 100%; transform: translateX(100%)`, |
| 82 |
* containing block = the fixed header) translates past the |
| 83 |
* header's right edge, NOT past the iframe's right edge. The |
| 84 |
* resulting visible strip is exactly 160px wide — the size of the |
| 85 |
* sidebar gap WC reserved for nothing. |
| 86 |
* |
| 87 |
* Reclaim the reservation: pin the header to full iframe width |
| 88 |
* inside chromeless. The activity panel then translates past the |
| 89 |
* iframe edge as WC's design intended, the gray strip disappears, |
| 90 |
* and the header's content uses the full window width. No |
| 91 |
* transform / overflow / visibility tricks needed. |

| 135 |
* the add-new flow on many plugin pages (WooCommerce Orders, custom |
| 136 |
* CPTs, plugin settings pages, etc.). Earlier versions of this CSS |
| 137 |
* hid it on the assumption that the submenu tab strip exposed the |

* same action — which holds for WP Core pages with a registered |
| 139 |
* "Add New" submenu (Posts, Pages, Users) but breaks every third- |

| 185 |
* pages like `wc-orders` — the PHP-rendered legacy `.wrap` (with |
| 186 |
* the h1 + the "Add order" `.page-title-action`) AND a React-mounted |
| 187 |
* `EmbedHeader` (`client/admin/client/header/embed.tsx`) that |
| 188 |
* `position: fixed`-overlays the page from the top. References: |
| 189 |
* - `src/Internal/Admin/Loader.php::embed_page_header` |
| 190 |
* - `includes/react-admin/connect-existing-pages.php` (registers |
| 191 |
* wc-orders as a connected page when HPOS is on) |
| 192 |
* - `client/admin/client/header/shared.tsx::useUpdateBodyMargin` |
| 193 |
* (the hook that pushes `#wpbody.style.marginTop` to make |
| 194 |
* room for the fixed header) |
| 195 |
* |
| 196 |
* The conflict, narrowly: |
| 197 |
* 1. The legacy `.wrap > .page-title-action` ("Add order") at |
| 198 |
* the top of the document body — primary add-new affordance. |
| 199 |
* 2. The React `EmbedHeader` overlays the top of the iframe with |
| 200 |
* a redundant `<h1>Orders</h1>` and an Activity Panel toggle. |
| 201 |
* |
| 202 |
* The fixed React header OBSCURES the legacy `.page-title-action` |
| 203 |
* button when we reset `#wpbody`'s margin-top. |
| 204 |
* |
| 205 |
* Scope: ONLY the pages where the dual rendering is genuinely a |
| 206 |
* problem — `wc-orders` (Orders list, the user-reported failure |
| 207 |
* mode) and `wc-orders--shop_order` (the trash view variant). Other |
| 208 |
* WC-admin pages (Analytics, Marketing, Customers, Coupons, |
| 209 |
* Products, Reports, …) DON'T render a competing legacy `.wrap` |
| 210 |
* with a `.page-title-action` button; their primary content IS the |
| 211 |
* React app. On those pages the Activity Panel + EmbedHeader are |
| 212 |
* the only header affordance the user has, so we keep them visible. |
| 213 |
* |
| 214 |
* If new HPOS-style connected pages emerge where the same dual |
| 215 |
* layout creates the same conflict, add their per-page body class |
