What do you understand by column ordering in Bootstrap?

One of the most intriguing properties of bootstrap is column ordering. The columns can be readily written in a specific order by utilizing relevant functions. You might alternatively put them in a different column. Use the push and pull column classes to easily rearrange or rearrange the order of the columns. These classes are used in conjunction with the .col-xs-#, .col-sm-#, .col-md-#, and .col-lg-# Bootstrap grid classes.

.col-xs-push-# and .col-xs-pull-# are the push and pull classes for the Bootstrap grid. This also works well for sm, md, and lg. The pull class moves columns to the left, whereas the push class moves them to the right.
