Terasnet Responsive Web Build

I need a clean, high-contrast website for my WiFi company, Terasnet, built strictly with HTML, CSS, and vanilla JavaScript so it loads fast and remains easy to maintain. The color palette is black and electric blue, and the layout must scale gracefully from mobile screens to large desktops...
