Render Flow - How Tailwind differs from Bootstrap

[Load HTML] -> [Load CSS Framework] -> [Parse CSS Classes] -> [Apply Styles to Elements] -> [Render Visual Styles]

The browser reads the HTML and CSS framework files, parses the utility classes or components, applies styles to elements, and renders the final visual layout.

Common Confusions - 2 Topics

Why does Tailwind require many classes on one element?

Tailwind breaks styles into small utilities to let you combine exactly what you want, unlike Bootstrap's big component classes.

💡 Think of Tailwind classes like LEGO bricks you stack, Bootstrap classes like ready-made LEGO sets.

Why does Bootstrap feel easier for quick buttons?

Bootstrap provides pre-styled components so you add fewer classes, but less control on exact style details.

💡 Bootstrap components = ready meals; Tailwind utilities = cooking ingredients.
