Bootstrap 4, which was finalized in 2018, is widely used today, and it’s the version we recommend learning to get started with Bootstrap. Since its initial version in 2011, Bootstrap’s had several updates that added major features (such as navigation options).

This is the difference between the .container and .container-fluid class names. Once you set the display property to block , the image no longer honors the text-center style — as it is no longer an inline element.
