NDE Header Styling - COMPLETE

Date: 2025-11-22
Status: Complete

Summary

Successfully updated the Heritage Custodian Ontology frontend to match the exact header styling from the official Netwerk Digitaal Erfgoed (NDE) website at https://netwerkdigitaalerfgoed.nl/

Changes Applied

1. Header Title Shortened

  • Before: "NDE Heritage Custodian Ontology" + subtitle "Netwerk Digitaal Erfgoed"
  • After: "NDE HC Ontology" (single line, concise)

2. Exact NDE Header Spacing

Extracted from live NDE website inspection:

/* Navigation Container */
height: 100px;           /* Match NDE height */
padding: 0 3rem;         /* Fixed padding like NDE */
justify-content: space-between; /* Logo left, links far right */

/* Logo Spacing */
margin-right: 80px;      /* Match NDE logo spacing */

/* Navigation Links */
gap: 2rem;               /* Larger spacing between links */
margin-left: auto;       /* Push to far right */

3. NDE Typography Exact Match

/* Logo Title */
font-size: 16px;         /* Match NDE exactly */
font-weight: 400;        /* Regular weight */
color: #172a59;          /* NDE dark blue */

/* Navigation Links */
font-size: 16px;         /* Match NDE - relatively small */
font-family: 'Roboto';   /* Body font for nav */
font-weight: 400;        /* Regular weight */
color: #172a59;          /* Full opacity dark blue */

4. Welcome Section - Lighter Colors

Before: Dark gradient (#0a3dfa → #172a59) with white text
After: Very light gradient (#ebefff → #f6f6f6) with dark blue text

background: linear-gradient(135deg, #ebefff 0%, #f6f6f6 100%);
color: #172a59;          /* Dark blue text */
border: 1px solid rgba(10, 61, 250, 0.15); /* Subtle border */

5. Exact NDE Color Palette

Extracted from live website:

Color Name Hex Code RGB Usage
Primary Blue #0a3dfa rgb(10, 61, 250) Buttons, links, accents
Dark Blue #172a59 rgb(23, 42, 89) Primary text color
