Button

Buttons are used to trigger actions in forms, modals, and more.

Button tags

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.

Link

<!-- 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">

Examples

Base

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.

<!-- For light backgrounds -->
<button class="a-btn">Base</button>

<button class="a-btn -dark">Dark</button>
<!-- For dark backgrounds -->

<button class="a-btn -light">Light</button>

Outline

To remove a buttons solid background and keep its colored border, apply the class -outline.

<!-- For light backgrounds -->

<button class="a-btn -dark -outline">Dark</button>
<!-- For dark backgrounds -->
<button class="a-btn -secondary -outline">Secondary</button>
<button class="a-btn -light -outline">Light</button>

Flat

To render a button with a transparent background and border, apply the class -flat.

<!-- For light backgrounds -->
<button class="a-btn -primary -flat">Primary</button>
<button class="a-btn -dark -flat">Dark</button>
<!-- For dark backgrounds -->
<button class="a-btn -secondary -flat">Secondary</button>
<button class="a-btn -light -flat">Light</button>

Fluid

Buttons can be expanded to fill the parent space by applying the class -fluid.

<button class="a-btn -fluid">Button</button>

Icon buttons

For interfaces with limited space, an -icon button can be used for common actions such as editing, deleting, closing, etc.
