/* =========================================================
   BRONVERMELDING CSS
   =========================================================


   Tijdens het maken heb ik:
   - Veel getest en aangepast door trial & error
   - W3Schools gebruikt voor basis CSS (flexbox, media queries):
     https://www.w3schools.com/css/
   - ChatGPT gebruikt als hulp en sparringpartner om:
     • te begrijpen welke selectors ik moest gebruiken
     • problemen met layout en positioning op te lossen
     • dark / light mode te maken met CSS-variabelen
     • responsive gedrag te verbeteren

   De code is steeds aangepast zodat het past
   bij mijn HTML en ontwerp.
