What Is an HTML Boilerplate?
An HTML boilerplate is a starting template that includes all the essential elements every HTML page needs: the DOCTYPE declaration, character encoding, viewport meta tag, title, and basic structure. Starting from a solid boilerplate saves time and ensures you don't forget critical elements that affect SEO, accessibility, and rendering.
