Starting point
The previous website ran on WordPress with the Elementor page builder and a standard theme. Its PageSpeed score was around 60 out of 100 on both desktop and mobile.
The goal was a contemporary, professional appearance with a clear content structure and responsive design – accessible and fast.
Approach
Concept & information architecture
The content was restructured: a home page with a topic overview and latest news, plus About, Projects, Publications, Talks & Workshops, Press, Media and Contact.
Design & responsive frontend
A calm, readable layout based on Bootstrap 5 with its own stylesheet. The logo is an SVG, images are served as WebP with a JPG fallback.
Technology & performance
PHP without a CMS or framework, libraries hosted locally instead of via a CDN. For load time: font-display swap, fetchpriority for the largest image and a smaller image variant on smartphones.
Accessibility, privacy & contact
YouTube videos only load after a click and their thumbnails are hosted locally (GDPR). A honeypot protects the contact form from spam.
