Centering Elements in Twitter Bootstrap
When working with Twitter Bootstrap, the need arises to center elements within their parent containers. Here are the methods you can use:
Horizontal Centering:
1. text-center Class: Use the text-center class on the parent container to horizontally align all child elements.
2. Inline Styling: Set the text-align: center CSS property on the parent container or the child element you want to center.
3. Offsets (New Methode): Introduced in Bootstrap 4, the mx-auto class adds horizontal margins to an element, causing it to be centered.
Vertical Centering:
1. padding-top and padding-bottom: Use padding-top and padding-bottom properties on the parent container to add vertical spacing and center the child elements.
2. Absolute Positioning: Position the child element absolutely and set top: 50%; and transform: translate(-50%, -50%).
Note: The above solutions are applicable to older versions of Bootstrap. For Bootstrap 4 and up, the mx-auto class is the recommended approach for horizontal centering.
