Blog

Hi! I'm David Allen, and I built this website for a college class project.

You might be wondering, why is this website so fast? It’s because it’s simple and lightweight! Even though I’m using the Bootstrap 5.3's Content Delivery Network(CDN) for styling, everything else is streamlined into a single HTML file. By leveraging the efficiency of a CDN, the Bootstrap files load quickly from servers around the world, while the rest of the content loads instantly because it’s all right here in one file. And without any images this website scores a 0.39s "Largest Contentful Paint" (LCP), with a "Cumulative Layout Shift" (CLS) value of 0.00!

Fast websites aren’t just nice for users—they’re also crucial for SEO. Google uses page speed as a ranking factor, so faster sites tend to rank higher in search results. Plus, speed improves user experience by reducing bounce rates and keeping visitors engaged, especially on mobile devices where slow-loading sites can frustrate users. In short, a fast site isn’t just about performance; it’s about making sure people can actually find and enjoy your content.

Want to experiment with lightweight web design yourself? Play with it live with my previous recommendation CodePen.io!
