Center a heading¶
<h2 class="text-center">your text</h2>
button elements with the
btn-default classes are only as wide as the text that they contain. For example:
<button class="btn btn-default">Submit</button>
This button would only be as wide as the word "Submit".
By making them block elements with the additional class of
btn-block, your button will stretch to fill your page's entire horizontal space and any elements following it will flow onto a "new line" below the block.
<button class="btn btn-default btn-block">Submit</button>
This button would take up 100% of the available width.
