Buttons
Buttons are used to carry out actions. Use them when you should enable or initiate an immediate action within your application e.g. “OK”, ”Save”, ”Continue” or ”Submit.” Read more about buttons in the UX Guidelines.
Use the button classes on an <a>
, <button>
, or <input>
element. Also you can use any of the available button classes to quickly create a styled button: .btn-default
or .btn-primary
or even to large version of it: .btn-lg
Design
Use any of the available button classes to quickly create a styled button. On this page you can find multiple types of buttons and the class you need to use for each option:
Options
Standard buttons New
Add .btn
for default buttons and .btn-primary
for primary style. Also you can add .btn-destructive
class to a default or primary button to transform it from a confirmatory to a destructive button.
Use the primary button to:
- Highlight the primary action in the screen, which shall be the main and/or finalising action
- Emphasise either normal buttons, menu buttons or split buttons
Use the destructive button to:
- Nullify/delete an action/process
- It is not a validation state (has-error state) or cancel
<!-- Default button - .btn -->
<!-- Primary button - .btn.btn-primary -->
<!-- Destructive button - .btn.btn-destructive -->
<!-- Primary destructive button - .btn.btn-primary.btn-destructive -->
Sizes - Large buttons
Fancy larger buttons? Add .btn-lg
for a larger size.
<!-- Default button - .btn.btn-lg -->
<!-- Primary button - .btn.btn-lg.btn-primary -->
<!-- Destructive button - .btn.btn-lg.btn-destructive -->
<!-- Primary destructive button - .btn.btn-lg.btn-primary.btn-destructive -->
Directional buttons
Add .left
or .right
class together with .btn
class for the direction needed.
Use when:
- To indicate the direction of a flow, e.g. to go to the next or previous step in a wizard
- To indicate the direction in which data will change when an action will take place, e.g. to move data from one grid to another
Sizes - Large buttons
Fancy larger buttons? Add .btn-lg
for a larger size.
Squerkle buttons
Add .btn-squerkle
class together with .btn
class to have a button like the ones from below. To change the background color you can use or background color helper classes and also to change the size you can do that by changing the padding using the helper classes for paddings. Check out the examples below and the code snippets.
** We recommend you to use this buttons on: 48px x 48px, 32px x 32px and 24px x 24px.
Default - .btn.btn-squerkle
.btn.btn-squerkle.bg-secondary
.btn.btn-squerkle.bg-primary

Link buttons (with and without icons) and icon buttons
You can also use .btn-link
and .btn-icon
. Both will have the height of a default button but won't have the button styling.
Checkout the examples below.

Icon buttons - .btn.btn-icon
<!-- Link button - .btn.btn-link -->
<!-- Link button with icon - .btn.btn-link -->
<!-- Icon button without text/label - .btn.btn-icon -->
Buttons with transparent background on normal state New
You can use .btn-link
with .btn-default
or .btn-destructive
class for having a button link design to have the interaction style of a default or destuctive button.
Default size
Large button - .btn-lg
<!-- Link button default - .btn.btn-default.btn-link -->
<!-- Link button destructive with icon - .btn.btn-destructive.btn-link -->
Login buttons
Different type of buttons used for login pages.
Default login button .btn-login
Secondary login buttons .btn-login-secondary
<!-- Default login button - .btn-login -->

States Update
Below you can find each type of button (default and primary) and how it should look for each state (normal, hover, pressed, active/selected and disabled).
For active/selected state you need to add .active
class on the element and include the aria-selected="true"
attribute to indicate the state of the element to assistive technologies.
For disabled state (buttons are unclickable) add .disabled
class on your button or add the disabled
attribute to <button>
or <input>
buttons. <a>
tag don't support the disabled
attribute, so you must add the .disabled
class to make it visually appear disabled. For disabled buttons, that include .disabled
class and <a>
tag, they should include the aria-disabled="true"
attribute to indicate the state of the element to assistive technologies.
Normal
:hover
:active (Pressed)
.active (Selected)
:focus
:disabled
Block button
Create block level buttons, those that span the full width of a parent, by adding .btn-block
.
