In Tailwind CSS, you apply styles to HTML elements by using classes provided by the framework. However, Tailwind CSS doesn't have specific classes for every HTML tag by default.

For example, if you want to style an <h1> heading element, you won't find a class like h1 in Tailwind CSS to do that directly. Instead, Tailwind CSS focuses on providing utility classes that can be combined to create custom styles.

To style an <h1> element in Tailwind CSS, you can use utility classes like text-3xl for setting the font size, font-bold for making the text bold, and text-blue-500 for setting the text color to blue
