Modern web design starts with speed: compress images, use WebP/SVG, minimize scripts, enable lazy loading, and keep layouts responsive so every screen feels effortless. Make accessibility your standard—clear contrast, readable type, alt text, focus states, and keyboard navigation. Clean semantic HTML, tidy metadata, and meaningful links boost SEO without gimmicks. Choose lightweight templates, avoid bloat, run audits, watch analytics, and iterate for a site people love to use.
