Buttons are used to trigger actions in forms, modals, and more.
To render a button, apply the class a-btn
to a <button>
element.
Although buttons were designed for the <button>
element, Chi
also supports button classes on <a>
and <input>
elements.
<!-- default tag -->
<button class="a-btn">Button</button>
<!-- tags also supported -->
<a class="a-btn" role="button">Link</a>
<input class="a-btn" type="button" value="Input">
<input class="a-btn" type="submit" value="Submit">
<input class="a-btn" type="reset" value="Reset">
Chi includes a wide variety of predefined button styles. For light backgrounds,
please use base, -primary
, or -dark
buttons. For
dark backgrounds, please limit usage to -secondary
or -light
.

.

be used for common actions such as editing, deleting, closing, etc.
