In Bootstrap-5 some performance optimizations and improvements over Bootstrap 4 have been incorporated. These changes are concerned with writing more contemporary wiring of the framework, increasing velocity and modularity, and decreasing reliance on supplemental programs. Here’s a summary of the key improvements:
Removal of jQuery Dependency
Bootstrap 5 no longer depends on jQuery, which thus brings its small size and better performance, as well as better integration with popular JavaScript frameworks like React, Vue, and Angular.
Improved Grid System
New
xxlbreakpoints for additional extra-large screens andgx-*andgy-*classes increase additional control over horizontal and vertical gaps, increasing the layout’s usability and responsiveness.Use of CSS Custom Properties
Makes it easier to apply themes, makes it easier to customize, and create small CSS files that don’t need to be compiled again.
Refactored JavaScript
The plugins have become application components, and all plugins are written in modern ES6+ features, so one can include only necessary components and plugins, and the sizes of bundles are optimal.
Responsive Font Sizes (RFS)
They adapt themselves to the size of the viewport which increases cross-device readability without additional editing.
Redesigned Forms
Many forms become uniform, spaced evenly, use more efficient DOM structures, and thus, become more accessible, manageable, and aesthetic.
Accessibility Enhancements
Bootstrap 5 brings enhancements to ARIA attributes, stays compliant with WCAG 2.1, and provides better Screen Reader support.
Bootstrap Icons
It also contains a simple, lightweight SVG icon set rather than using any extra large external libraries.
Optimized Sass Compilation
Predominantly, faster Sass compilation and the implementation of imports limited to certain components make builds shorter and CSS as a result lighter.
Improved Utility API
The renewal of the utility classes API makes it possible to enhance the original settings of utility classes thus enhancing the execution of a project.
