Overview of Bootstrap

Bootstrap is a widely-used front-end framework designed to aid developers in creating responsive and mobile-first websites with ease. It offers a robust collection of CSS and JavaScript components that streamline the process of web design.

Key Concepts

• Responsive Design: Bootstrap enables web pages to adapt seamlessly to various screen sizes and resolutions, ensuring an optimal user experience across mobile devices, tablets, and desktops.
• Grid System: Bootstrap’s grid system leverages a series of containers, rows, and columns to effectively layout and align content. This flexible structure allows for straightforward customization.
• Predefined CSS Classes: Bootstrap includes numerous predefined classes for typography, forms, buttons, tables, navigation, and more, simplifying the styling process.
• JavaScript Components: Bootstrap offers a variety of JavaScript plugins for enhanced functionalities such as modals, dropdowns, carousels, and more, improving user interaction on websites.

Example:

<button class="btn btn-primary">Click Me</button>

Example:

<div class="container">
    <div class="row">
        <div class="col-md-4">Column 1</div>
        <div class="col-md-4">Column 2</div>
        <div class="col-md-4">Column 3</div>
    </div>
</div>
