Centering content blocks with buttons

The center-block class is fine to achieve a centered button only if it is really a button element. Applying to a link button does not work.

Examples (both cases):

• <button type="button" class="btn btn-default center-block">Pure button</button>.
• <a href="#" class="btn btn-default center-block">Link button</a>.

Using center-block class, buttons are not inline-block. This class has not to be applied to buttons or links? Only devised for images and resized divs?

Here is a solution.

A CSS declaration like a.center-block { display: table; } is usefull.
