Bootstrap provides different styles of buttons. You can use any of the available button classes to quickly create a styled button. As a best practice, Bootstrap highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.
All HTML headings, <h1> through <h6>, are available. .h1 through .h6 classes are also available, for when you want to match the font styling of a heading but still want your text to be displayed inline.
