Add any of the below mentioned modifier classes to change the appearance of a badge.
                                                Use the badge-soft-* class for badge lighten.
                                            
                                                Use the .badge-pillmodifier class to make badges more rounded (with a larger border-radius and additional horizontal padding). Useful if you miss the badges from v3.
                                            
The best part is you can do this with any button variant, too:
                                    Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-splitfor proper spacing around the dropdown caret.
                                
                                    Trigger dropdown menus above elements by adding .dropup, .droprightand .dropleftto the parent element.
                                
                                    Add .dropdown-menu-right to a .dropdown-menuto right align the dropdown menu.
                                
Pagination links indicate a series of related content exists across multiple pages.
                                            Pagination links are customizable for different circumstances. Use .disabledfor links that appear un-clickable and .activeto indicate the current page.
                                        
                                            Fancy larger or smaller pagination? Add .pagination-lgor .pagination-smfor additional sizes.
                                        
Change the alignment of pagination components with flexbox utilities.
Add small overlay content, like those found in iOS, to any element for housing secondary information.

Indicate the current page’s location within a navigational hierarchy that automatically adds separators via CSS.
Use the border spinners for a lightweight loading indicator.
If you don’t fancy a border spinner, switch to the grow spinner. While it doesn’t technically spin, it does repeatedly grow!
