Differences Between Bootstrap 3 and Bootstrap 4

Bootstrap is a popular framework for building responsive and mobile-first websites. Understanding the differences between Bootstrap 3 and Bootstrap 4 can help developers choose the best version for their projects.

Key Differences

• Grid System: The grid system in Bootstrap 4 has been rebuilt with a new flexbox model, offering more flexibility and customization options compared to Bootstrap 3.
• Typography: Bootstrap 4 introduces a new card component that replaces the panel and thumbnail components found in Bootstrap 3.
• Utilities: Bootstrap 4 includes new utility classes for spacing and sizing, making it easier to create responsive designs without custom CSS.
• Improved Customization: Bootstrap 4 allows for greater customization through SASS variables and mixins, unlike Bootstrap 3 which heavily relies on precompiled CSS files.

Overall, Bootstrap 4 focuses on modern web design practices and provides more flexibility and customization options compared to Bootstrap 3. Developers should consider the specific needs of their projects when choosing between the two versions.
