Buttons should be written using the
<button> html tag. However, if a button is an
<a> tag styled with the
.btn class and has in-page functionality (such as toggling elements), the
role attribute should be set to “button” and the
tabindex attribute should be set to “0.” Refer to the best practices illustrated in the MDN documentation for the “button” role.
If the button is a
<button> element and appears within a
<form> tag, the
type attribute should be explicitly set to “submit,” “reset,” or “submit.” By default (without the type attribute)
<button> elements are set to the “submit” type.
The base button class,
.btn, is extended with additional button classes below.
