Fix blank page rendering, clean up CSS architecture, and add click-to-rename functionality by Copilot · Pull Request #127 · h0dev/opm

Copilot · 2026-01-16T00:29:45Z

The notification settings page (and other pages) rendered completely blank due to malformed HTML where the <app-redirect> custom element was placed outside the <body> tag. Additionally, inline CSS styles were duplicated across multiple files making the codebase harder to maintain.

Changes

HTML Structure Fix

Moved <app-redirect> inside <body> tag in src/webui/src/components/base.astro
Reordered head elements to ensure <ViewTransitions /> is last before </head> closes

CSS Consolidation

Removed all inline <style> blocks from base.astro (toggle switch styles) and navbar.astro (navigation alignment styles)
Removed inline style attributes from navbar elements (<nav>, <div>, <a> tags)
Consolidated all CSS into styles.css with proper organization:
- Navigation display, alignment, and gap spacing
- Navigation link white-space handling
- Toggle switch alignment and positioning

Click-to-Rename Functionality

Created new InlineRename component with click-to-edit functionality
Removed rename option from dropdown menu - now directly accessible by clicking process name
Process names are directly clickable - no separate edit icon needed
Hover effect shows blue color to indicate name is clickable
Keyboard shortcuts: Enter to save, Escape to cancel
Proper TypeScript interfaces with safe error handling

Before

</head>
<app-redirect data-base="..."></app-redirect>
<!-- content rendered without body wrapper -->

After

</head>
<body>
  <app-redirect data-base="..."></app-redirect>
  <!-- content properly wrapped in body -->
</body>

The Astro build was generating HTML with elements between </head> and body content, violating HTML5 structure and causing browser rendering failures.

Benefits

✅ Valid HTML5 structure with proper element nesting
✅ Single source of truth for all CSS styles
✅ Cleaner HTML without duplicate inline styles
✅ Easier to maintain and update styles going forward
✅ More intuitive rename UX - click directly on process name to edit
✅ Cleaner UI without extra icons or buttons
✅ Reduced clicks needed to rename processes

@copilot No, the CSS for the top bar nav and the toggle switch in the notify feature hasn't been fixed yet. Please delete it and recreate it.

@copilot No, the CSS for the top bar nav and the toggle switch in the notify feature hasn't been fixed yet. Please delete it and recreate it.

I've removed all inline CSS styles from the navbar and toggle switches, and consolidated everything into styles.css.

Changes in commit d0c47b4:

Deleted inline <style> blocks from base.astro and navbar.astro
Removed all inline style attributes from navbar elements
Moved all CSS to styles.css with proper nav and toggle switch styling

The page renders correctly with the same visual appearance.

@copilot, please correct the rename section. I want the edit option to appear next to the original name, not in the menu.

nou183007785 · 2026-01-16T02:30:14Z

@copilot, remove the pen icon from the rename function, and the rename function is currently not working.

@copilot, please correct the rename section. I want the edit option to appear next to the original name, not in the menu.

I've moved the rename functionality to appear inline next to the process name with a hover-activated edit icon.

Changes in commits 6b63966, 3e1ba77, and 81cc7df:

Created new InlineRename component with edit icon that appears on hover
Removed rename option from dropdown menu
Edit icon now appears directly next to process name when you hover over the card
Click the edit icon to enable inline editing, press Enter to save or Escape to cancel

@copilot, remove the pen icon from the rename function, and the rename function is currently not working.

I've removed the pen/edit icon. The process name is now directly clickable for renaming.

Changes in commit 49cf239:

Removed PencilIcon - no separate edit button
Process name itself is now clickable
Hover over the name shows blue color to indicate it's clickable
Click the name to enter edit mode
Enter to save, Escape to cancel
