HTML has evolved significantly over the years, and with the latest updates in HTML5, it’s more powerful than ever. Many developers still rely on outdated practices, missing out on modern features that can improve performance, SEO, and user experience.
In this blog, we’ll explore the top 10 HTML features you might not be using—but definitely should—in 2025.
