Bootstrap 5 Approach

Last Updated : 29 Jul, 2024

Bootstrap 5 Approach simplifies customization and extension, providing principles and strategies for tailored development. It manages viewport behavior, ensuring optimal rendering on diverse devices. By setting viewport width and scale, enables responsive design, adjusting content for optimal viewing.

Bootstrap 5 facilitates the different approaches to customizing the design of the webpage which are described below:

Concept	Description
Responsive	Bootstrap's styles apply progressively with min-width queries for mobile-first responsiveness.
Classes	Bootstrap primarily uses classes for selectors, simplifying overrides and variations.
Z-index Scale	Utilizes two z-index scales for component elements and overlays like modals and tooltips.
Utilities	Utility classes combat CSS bloat, optimize performance, and reduce the need for custom CSS.
Flexible HTML	Focuses on single classes, avoids immediate children selectors for flexible component implementation.

Example 1: In this example, we use a responsive navbar and a section with introductory text. It utilizes Bootstrap 5 classes for styling and responsiveness.

                    frameworks which has really a nice set of predefined 
                    CSS codes. Bootstrap uses different types of
                    classes to make responsive websites. Bootstrap 5 was 
                    officially released on 16 June 2020 after
                    several months of redefining its features. </p>
