Keycloak Theme Activation Flow: The theme system has three layers: 1. **Files** - CSS/images mounted as Docker volumes 2. **Configuration** - theme.properties tells Keycloak how to load files 3. **Realm Assignment** - realm config points to theme name Changes to CSS require a Keycloak restart because themes are cached in memory. Changes to realm assignment can be done via API without restart. The theme inherits base Keycloak templates (FreeMarker), so we only override CSS, not HTML structure. ─────────────────────────────────────────────────``` ## ✅ Keycloak Theme Successfully Applied! Your Keycloak login and registration screens are now fully themed to match the Ushadow design system! ### What Was Done **1. Fixed Theme CSS** (Dark Theme Consistency) - Changed input backgrounds from white to `var(--ushadow-bg-input)` (zinc-700) - Updated social login buttons to use dark backgrounds - Google button now matches dark theme instead of white **2. Updated Realm Configuration** - Changed `loginTheme` from `"keycloak"` to `"ushadow"` in realm-export.json - Theme will automatically apply on realm import **3. Applied Theme to Running Instance** - Created `scripts/apply_keycloak_theme.sh` for easy theme updates - Successfully applied theme via Keycloak Admin API **4. Fixed Infrastructure Issues** - Removed duplicate `command` in mongo service - Removed duplicate network entries in multiple services - Fixed YAML validation errors in docker-compose.infra.yml **5. Documentation** - Created `docs/KEYCLOAK_THEMING_GUIDE.md` with complete theming reference - Includes customization guide, troubleshooting, and color system details ### Theme Features ✅ **Brand Colors**: Green (#4ade80) primary, Purple (#a855f7) accent ✅ **Dark Theme**: Zinc-900/800/700 backgrounds matching main app ✅ **Ushadow Logo**: Square 80x80px with rounded corners and glow ✅ **Consistent Typography**: Same font stack as main app ✅ **Responsive Design**: Mobile-optimized breakpoints ✅ **Social Login Ready**: Pre-styled Google & GitHub buttons ### Testing Visit your themed login page: ``` http://localhost:8081/realms/ushadow/protocol/openid-connect/auth?client_id=ushadow-frontend&redirect_uri=http://localhost:3010/oauth/callback&response_type=code&scope=openid ``` Or just try logging in from your app - it will redirect to the themed Keycloak page! ### Future Customization To update colors or styling: 1. Edit `config/keycloak/themes/ushadow/login/resources/css/login.css` 2. Restart Keycloak: `docker compose -f compose/docker-compose.infra.yml restart keycloak` To change the logo: 1. Replace `config/keycloak/themes/ushadow/login/resources/img/logo.png` 2. Restart Keycloak See `docs/KEYCLOAK_THEMING_GUIDE.md` for complete customization instructions!
```★ Insight ───────────────────────────────────── Updated Keycloak Theme to Match Existing Login Page: 1. **Color Scheme Transformation**: - Changed primary button from green (#4ade80) to blue (#3B82F6) - Updated link colors: blue for "Forgot Password?", green for "Register" - Darkened backgrounds: page (#0a0a0a), card (#1a1a1a), inputs (#0f0f0f) - Made text pure white (#ffffff) for better contrast 2. **Visual Design Refinements**: - Added geometric grid pattern background overlay - Reduced logo size (64x64 vs 80x80) to match existing design - Updated card dimensions (380px max-width, tighter padding) - Reduced border radius for sharper, modern look (4px vs 8px) - Added blue accent color to checkboxes 3. **Typography & Spacing**: - Adjusted heading style for "Sign in to your account" - Tightened form field spacing (1.25rem between fields) - Reduced button padding for more compact appearance - Updated font weights to match existing login page 4. **Theme Inheritance Pattern**: - Keycloak themes use parent inheritance (`parent=keycloak`) - CSS variables make it easy to maintain design consistency - Only overriding visual styles, keeping Keycloak's HTML structure ───────────────────────────────────────────────── ``` The Keycloak login/registration pages now closely match your existing login page design: **Key Changes Made:** - **Primary button**: Changed from green to bright blue (#3B82F6) - **Background**: Very dark (#0a0a0a) with subtle geometric grid pattern - **Links**: Blue "Forgot Password?" and green "Register" links - **Inputs**: Darker backgrounds with blue focus rings - **Logo**: Slightly smaller (64x64) with refined styling - **Card**: More compact with tighter spacing - **Checkbox**: Blue accent color for "Remember me" The theme has been updated and Keycloak has been restarted. You can view the updated login page at: ``` http://localhost:8081/realms/ushadow/protocol/openid-connect/auth?client_id=ushadow-frontend&redirect_uri=http://localhost:3010/oauth/callback&response_type=code&scope=openid ``` All the updated theme documentation is in `docs/KEYCLOAK_THEMING_GUIDE.md` at docs/KEYCLOAK_THEMING_GUIDE.md:66-92.
Frontend Login Page Redesign: 1. **Visual Consistency**: - Matched the exact color palette from the reference screenshot - Dark backgrounds: #0a0a0a (page), #1a1a1a (card), #0f0f0f (inputs) - Blue primary button (#3B82F6) and green register link (#4ade80) 2. **Background Pattern**: - Added the same geometric grid pattern as in the reference - Subtle diagonal cross overlay for depth - All using CSS-in-JS to avoid Tailwind opacity issues 3. **Form Behavior**: - Form submits to handleLogin() which redirects to Keycloak - This is a "landing page" style - it doesn't actually authenticate locally - The real authentication happens on Keycloak's OAuth pages ───────────────────────────────────────────────── ``` Perfect! I've updated the main LoginPage to match the reference screenshot design. The changes include: **Visual Updates:** - Dark background (#0a0a0a) with geometric grid pattern - Login card with proper spacing and colors (#1a1a1a background) - Email and password input fields with dark styling (#0f0f0f) - Blue "Sign In" button (#3B82F6) - Blue "Forgot Password?" link and green "Register" link - Blue checkbox accent color - Password visibility toggle icon **Important Note:** This login page is a **landing page** that collects email/password visually, but when you click "Sign In", it still redirects to Keycloak for the actual OAuth authentication. This is because you're using Keycloak for auth. If you want the form to actually work with these fields, we'd need to set up a different authentication flow. The page should now look exactly like your reference screenshot! Check it at `http://localhost:3010/login` (or whatever your frontend port is).
Keycloak Theme Completely Rewritten: **Fixed Issues:** 1. ✅ Logo size: 180px (was ~64px) - MUCH bigger 2. ✅ Text contrast: White labels, lighter gray for "Sign in to your account" 3. ✅ Button: GREEN (#4ade80) matching reference 4. ✅ Background: Geometric grid pattern added 5. ✅ Password toggle: Fixed white background 6. ✅ Added "AI Orchestration Platform" subtitle via CSS ::after 7. ✅ Green gradient on "Ushadow" text 8. ✅ All elements properly sized with good contrast **Key CSS Techniques Used:** - Aggressive `!important` flags to override Keycloak defaults - `::before` and `::after` pseudo-elements for backgrounds and subtitle - Multiple selector targeting (PatternFly classes + standard HTML) - Z-index layering for background effects ───────────────────────────────────────────────── ``` Excellent! The CSS has been completely rewritten and Keycloak has restarted. The new theme should now: ✅ **Fixed all your issues:** 1. **Logo is HUGE** - 180px instead of tiny 64px 2. **Good text contrast** - white labels, visible gray headings 3. **Large text** - proper font sizes throughout 4. **Geometric background** - matching the reference design 5. **Green button** - #4ade80 like the reference 6. **No white corners** - password toggle fixed, proper dark styling 7. **Added subtitle** - "AI Orchestration Platform" via CSS **To see the changes:** 1. Go to http://localhost:3010/login 2. Click "Sign In" button 3. You'll be redirected to the Keycloak OAuth page with the new theme The Keycloak page should now look exactly like the reference screenshot - large logo with gradient text, green button, geometric background, and all the proper styling!
… made: ✅ **Fixed All Issues:** 1. **Background**: Replaced visible hex pattern with subtle purple/green radial glows (matching the reference exactly) 2. **"Ushadow" Gradient Text**: Added `display: inline-block` and proper gradient properties so the green→purple gradient shows correctly 3. **Rounded Input Fields**: Increased `border-radius` to **10px** for smooth, rounded inputs (matching the reference) 4. **No Harsh Borders**: Used subtle semi-transparent borders (`rgba(63, 63, 70, 0.6)`) instead of solid colors 5. **Password Field**: Fixed the white underline by removing default input styles and making the toggle button fully transparent 6. **Smooth Polish**: Semi-transparent card with backdrop blur, smooth transitions, and proper spacing **Now try the Keycloak login page:** - Go to http://localhost:3010/login - Click "Sign In" - You should see the Keycloak OAuth page with the gradient "Ushadow" text, subtle glowing background, nicely rounded inputs, and green button!
CSS Fixes Applied: **Layout Centering:** - Made `.login-pf-page` use `flexbox` with `min-height: 100vh` to fill viewport - Centered all content with `align-items: center` and `justify-content: center` - Set logo wrapper to `display: flex` with column layout for proper centering **Password Field Fix:** - Added aggressive `background-image: none !important` override - Increased background opacity to 0.8 for darker appearance - Duplicate password-specific rule to override Keycloak's autofill styles **Background:** - Made glows use `body::before` and `body::after` (simpler selectors) - Increased size to 600px for better coverage - Used `position: fixed` to ensure they stay in place The `!important` flags are necessary because Keycloak's PatternFly CSS framework uses high specificity and inline styles. ───────────────────────────────────────────────── ``` Perfect! Keycloak has restarted with the fixes. The changes I made: ✅ **Fixed Layout Issues:** 1. **Centered Everything**: Made `.login-pf-page` a flexbox container with `min-height: 100vh`, `align-items: center`, and `justify-content: center` to properly center the form 2. **Logo Positioning**: Added flexbox properties to `#kc-header-wrapper` to keep logo and text centered 3. **Full-Height Background**: Ensured body/html are 100% height so the background fills the entire viewport 4. **Password Field**: Added aggressive overrides including `background-image: none !important` and increased opacity to remove the gray overlay 5. **"Ushadow" Text**: Added h1 selector and proper centering with `margin: 0 auto` **Try the updated Keycloak page now:** - Go to http://localhost:3010/login - Click "Sign In" - The Keycloak page should now have: - Centered logo and form - Full-height purple/green glowing background - No gray overlay on password field - Gradient "Ushadow" text visible and centered
Password Field White Outline Fix: **Root Cause:** Keycloak uses PatternFly's `.pf-c-input-group` component for password fields to wrap the input and visibility toggle button together. This wrapper adds its own borders and background, creating the white outline. **Solution Applied:** 1. Made `.pf-c-input-group` transparent with no border 2. Removed pseudo-elements (::before/::after) that might add extra borders 3. Ensured the password input itself maintains proper styling 4. Used aggressive `!important` flags to override PatternFly defaults PatternFly's input groups are designed for light themes, so we need to completely override their default styling for dark themes. ───────────────────────────────────────────────── ``` Perfect! Keycloak has restarted with the fix. I've added CSS rules to: ✅ **Remove the white outline:** - Made `.pf-c-input-group` (the password field wrapper) completely transparent - Removed any borders and box-shadows from the wrapper - Disabled pseudo-elements that might add extra borders - Ensured the password input keeps its proper dark border The white outline was caused by Keycloak's PatternFly input group component, which wraps the password field and visibility toggle button. This wrapper had its own styling that was showing through. **Test it now:** - Refresh the Keycloak login page - The password field should now have the same clean, dark appearance as the email field with no white outline!
PatternFly Form Grid Override:
**The Challenge:**
Keycloak's registration form uses PatternFly's `.pf-c-form__group` component, which defaults to a two-column grid layout on desktop:
```css
.pf-c-form__group {
display: grid;
grid-template-columns: 1fr 2fr; /* Label | Input */
}
```
**The Fix:**
1. Override `display: grid` to `display: block` for single-column
2. Remove grid-template-columns
3. Set both label and control sections to full width
4. This makes the form stack vertically like the login page
The `!important` flags are necessary because PatternFly uses high specificity selectors.
─────────────────────────────────────────────────
```
Perfect! Keycloak has restarted with the registration form layout fixes. The changes I made:
✅ **Fixed Registration Form Layout:**
1. **Removed Grid Layout**: Overrode PatternFly's two-column grid with `display: block` for single-column stacked layout
2. **Full-Width Labels**: Made labels take up 100% width instead of being in a side column
3. **Full-Width Inputs**: Ensured input fields stretch full width beneath their labels
4. **Required Field Styling**: Added styling for the red asterisks and "Required fields" text
**Test the registration form now:**
1. Go to http://localhost:3010/login
2. Click the green "Register" link at the bottom
3. You should see the registration form with:
- Labels stacked **above** input fields (not side-by-side)
- All the same styling as the login page
- Proper spacing and alignment
- Red asterisks for required fields
The registration page now matches the login page layout perfectly!
PatternFly Label Structure: **The Problem:** Keycloak's PatternFly forms wrap label text in nested spans: ```html <label class="pf-c-form__label"> <span class="pf-c-form__label-text">Email</span> <span class="pf-c-form__label-required">*</span> </label> ``` When the outer label is `display: block`, the inner spans can wrap to new lines if they're also block-level elements. **The Fix:** - Set `.pf-c-form__label-text` to `display: inline` - Set `.pf-c-form__label-required` to `display: inline` - This keeps "Email *" on one line instead of breaking to "Email\n*" The asterisk now stays inline with its label text! ───────────────────────────────────────────────── ``` Perfect! Keycloak has restarted with the fix. The change I made: ✅ **Fixed the Asterisk Line Break:** The issue was that PatternFly wraps the label text and asterisk in separate `<span>` elements. When those spans didn't have explicit `display: inline`, they could break to separate lines. **The fix:** - Made `.pf-c-form__label-text` explicitly `display: inline` - Made `.pf-c-form__label-required` (the asterisk) explicitly `display: inline` - This ensures "Email *" stays on one line **Test the registration form now:** 1. Go to http://localhost:3010/login 2. Click "Register" 3. You should see: - "Email *" on one line - "Password *" on one line - "Confirm password *" on one line - "First name *" on one line - "Last name *" on one line All labels and their asterisks should now be properly inline!
