“Buttons” Component

Design: zeplin.

Buttons are used for actions that a user can perform on a page. Unlike text links, buttons should not be used solely for navigational purposes. A button might bring a user to a new page to start a user flow, for instance, but it should not be used just to link to another page.

Button Labels

Button labels should always start with a verb (e.g. “Save changes”), to indicate its action-oriented purpose.
Avoid generic labels like “Submit”—the button label should adequately describe the action that the user will perform.
Button labels should always contain text. Don't use icon-only button labels, because icons are subject to interpretation. Exceptions apply to rare cases where an icon is well-recognized, e.g. on the toolbar of a rich text editor.
Button labels should follow sentence-case capitalization where the first word and proper nouns are capitalized.
Button labels should be as short as possible—3 words or fewer.
For buttons that confirm an action—e.g. to delete a payment method or generate a Course Certificate—the label should always be explicit. For instance, instead of “Yes” or “Ok”, it should say “Delete payment method”.
Button labels should be in the first person: for instance, “Submit my answer”.

Icons in Button Labels

Icons can be used to complement text in a button label. Often, this helps users quickly identify the function of a button.
Icons should have the right size (see Iconography).
Icons should be placed on the left of the text—the exception is for buttons with chevrons, where the chevron icon is placed on the right of the text.

Accessibility

<button> or <a> or element? The rule, in a nutshell, is pretty simple: use anchor only if it has a link, otherwise it should be a button. So, these examples are totally valid:

<a href="/home" class="button button--ghost">Press me</a>
<button class="link" type="button">Click me</button>

As for button element, we always recommend to specify a type: button or submit.
