When designing responsive layouts, it's often necessary to adjust the order of columns on smaller screens. This article addresses the specific issue of changing the column order in a Bootstrap 3 mobile layout, where a sidebar column currently stacks on top of the main content column.
Problem:
I have a responsive layout with a navbar, sidebar, and main content. On desktop, the layout appears as:
navbar [3][9]
However, on mobile, the layout changes to:
navbar [3] [9]
I would like to reverse the order on mobile to:
navbar [9] [3]
Solution:
While it's not possible to directly change the column order on mobile using Bootstrap's built-in grid system, there is a workaround. By reversing the order of the columns in the HTML code, you can manipulate how they appear on different screen sizes.
In this case, we have:
<div>
To reverse the order on mobile, change it to:
<div>
By default, this will display the main content first, even on mobile devices. The col-lg-push and col-lg-pull classes are used to reorder the columns on larger screen sizes, ensuring that the sidebar remains on the left and the main content on the right.
Note: This solution only works for large screen sizes (e.g., laptops). On smaller screens, the columns will still stack as intended by Bootstrap.
