Responsive Heading Title

This heading's size adapts to the screen. On small screens, it's `text-xl`. As the screen gets wider, it increases to `sm:text-2xl`, then `md:text-3xl`, `lg:text-4xl`, and finally `xl:text-5xl` on very large screens. This ensures readability and appropriate scale across devices.

How it works:

Tailwind's responsive prefixes ( sm: , md: , lg: , xl: ) allow you to apply different utility classes at specific breakpoints. For text size, you start with a base size (e.g., text-xl for mobile) and then override it for larger screens (e.g., sm:text-2xl ).
