Output
Bootstrap Dark offcanvas
Here we add .text-bg-dark to the .offcanvas and .btn-close-white to .btn-close for proper styling with a dark offcanvas.
If you have dropdowns within, consider also adding .dropdown-menu-dark to .dropdown-menu.
Responsive offcanvas classes hide content outside the viewport from a specified breakpoint and down.
Above that breakpoint, the contents within will behave as usual.For example, .offcanvas-lg hides content in an offcanvas below the lg breakpoint, but shows the content above the lg breakpoint.
Responsive offcanvas classes are available across for each breakpoint.
