Responsive has two modes of operation for controlling the visibility of columns at different display sizes. These two modes can be used separately or combined
together:
- Manually assigned class names for breakpoints - Assign a column a class name to tell Responsive which breakpoint(s) to show it in.
- Automatically - for columns without a breakpoint class name, it will be automatically removed if there is no room available on screen to show it. Columns
can be removed in priority order or right-to-left.
This section explores these two options.
