Grid system: Bootstrap 4 uses a flexbox-based grid system which is more flexible and powerful than the grid system in Bootstrap 3. It allows you to create complex layouts with more control over the alignment and distribution of elements.
Browser support: Bootstrap 4 supports newer CSS and JavaScript features, such as flexbox and grid, which allows for better support of modern browsers. Bootstrap 3, on the other hand, is not fully compatible with some of the newer browsers.
Navbar: The navbar in Bootstrap 4 has been redesigned to be more responsive and flexible. It also has more customization options.
Default font-size: Bootstrap 4 has increased the default font-size from 14px to 16px.
Card component: Bootstrap 4 introduced a new card component, which is a flexible and extensible content container.
Reboot: Bootstrap 4 includes a reboot, a set of element-specific CSS changes to normalize styles across all browsers.
No glyphicons: Bootstrap 4 removed the glyphicon feature and recommends using other icon libraries such as Font Awesome.
Improved form controls: Bootstrap 4 includes new classes for customizing the look and feel of form controls.
Dropped support for Internet Explorer 8 and 9
These are some of the main differences between Bootstrap 3 and Bootstrap 4. While Bootstrap 3 is still widely used, Bootstrap 4 offers more advanced features and improved browser support, making it a better choice for new projects.
