How to Center Elements Horizontally and Vertically in Twitter Bootstrap?

A Comprehensive Guide to Centering Elements in Twitter Bootstrap

When working with Twitter Bootstrap, the need to center elements vertically or horizontally within parent containers arises frequently. This versatile framework provides multiple approaches to achieve this alignment.

Horizontal Centering

1. text-center Class: Apply the text-center class to the parent container to center its content horizontally. This is a simple and effective method for both text and non-text elements.
2. mx-auto Class: If you need more flexibility and want to offset the centering, use the mx-auto class. It adds automatic margins to the left and right of the element, pushing it to the center.

Vertical Centering

Bootstrap does not offer a built-in utility for vertical centering. However, there are two common techniques:

1. Pagination-Centered Class: For vertically centering a single element within a container with pagination controls, apply the pagination-centered class to the pagination control wrapper.
2. Custom CSS: You can also use custom CSS to vertically center elements. For example, set the margin-top: auto and margin-bottom: auto properties on the element you want to center.

Note:

The text-center and pagination-centered classes have been deprecated in recent versions of Bootstrap. It is recommended to use the mx-auto and d-flex utilities instead.
