Introduction to Bootstrap
What a CSS framework gives you, and the grid system.
Bootstrap is a CSS (and JS) framework — a library of pre-written, tested styles and components (buttons, navbars, cards) you apply via class names instead of writing CSS from scratch.
Its core layout tool is a 12-column responsive grid: wrap content in `.container` > `.row` > `.col-*`, and Bootstrap handles spacing and responsiveness for you.
Utility classes (like `.text-center`, `.mt-3`, `.btn-primary`) let you style common needs directly in HTML — trading some markup verbosity for speed and consistency across a whole team.
