Identifying active Bootstrap breakpoints with a simple visual helper
Quickly identify the active Bootstrap breakpoint on any screen size with this simple visual helper. Add a small visual indicator to your HTML page and remove the guesswork from responsive design debugging.
When working with Bootstrap, it is not always obvious which breakpoint is currently active for a given screen width.
A straightforward solution is to add a breakpoint helper directly to the page using Bootstrap’s standard visibility classes. The example below uses the badge class as a visual indicator, but any clearly visible element will work.
By including the following CSS and HTML in the page, a rounded badge icon appears in the top-left corner, displaying the active breakpoint.
