Tailwind CSS is a tool for styling web pages. Instead of writing a separate named style for every element, a developer applies small classes that describe choices such as spacing, text size, or color.
For example, a button can receive classes for its padding, background, and rounded corners right where the button is written. Think of these as small style stickers that can be combined.
Tailwind can make design changes quick and consistent, but a page still needs thoughtful design. The classes do not decide what looks good, and teams should use them in a way that stays readable.
