Readme: o-buttons

o-buttons provides Sass mixins and variables to create buttons.

Markup

There are two types of buttons, primary buttons and secondary buttons.

Type Selector Brand Support
primary .o-buttons--primary master, internal, whitelabel
secondary .o-buttons--secondary master, internal, whitelabel
<button class="o-buttons o-buttons--primary">Submit</button>
<button class="o-buttons o-buttons--secondary">Cancel</button>

o-buttons CSS will work on <button> or <a> elements. It is important for accessibility that if you intend to style an <a> as a button, you give it the correct aria role.

Themes

A theme may be applied to a button to change its appearance. o-buttons provides some themes by default:

Theme Selector Works With Types Brand Support
inverse .o-buttons--inverse primary, secondary master, internal
mono .o-buttons--mono primary, secondary master, internal
b2c .o-buttons--b2c primary master
<button class="o-buttons o-buttons--primary o-buttons--inverse">Submit</button>
<button class="o-buttons o-buttons--secondary o-buttons--inverse">Cancel</button>

Sass users may create custom themes.

Sizes

Any button may be made larger using the o-buttons--big modifier class.

<button class="o-buttons o-buttons--primary o-buttons--big">Click Me</button>

Icons

To add an icon to your button add the class o-buttons-icon and o-buttons-icon--{icon-name} to your button.

Sass users may output any icon from the fticons set. However if you're using the Build Service a limited number of button icons are available. Limiting the number of icons keeps the CSS bundle smaller, but if you need an icon button that we don't currently support then please contact the Origami team:

<button class="o-buttons o-buttons--secondary o-buttons-icon o-buttons-icon--arrow-down">Down Arrow</button>
<button class="o-buttons o-buttons--secondary o-buttons-icon o-buttons-icon--download">Download</button>

If you would like your button to display only an icon, add the class o-buttons-icon--icon-only and provide a visually hidden label for screen-reader users with o-buttons-icon__label.

<button class="o-buttons o-buttons--secondary o-buttons-icon o-buttons-icon--arrow-down o-buttons-icon--icon-only">
    <span class="o-buttons-icon__label">
        Down Arrow
    </span>
</button>

Groups

Wrap buttons with .o-buttons-group to group them together:

<div class="o-buttons-group">
    <button class="o-buttons o-buttons--secondary" aria-selected="true">One</button>
    <button class="o-buttons o-buttons--secondary">Two</button>
    <button class="o-buttons o-buttons--secondary">Three</button>
</div>

Pagination

For a pagination style wrap your buttons in .o-buttons-pagination. In this example we show pages 1-3 and use icon buttons to indicate more and fewer results:

<div class="o-buttons-pagination">
    <button class="o-buttons o-buttons--secondary o-buttons-icon o-buttons-icon--arrow-left o-buttons-icon--icon-only" disabled="disabled">
        <span class='o-buttons-icon__label'>Fewer results</span>
    </button>

    <button class="o-buttons o-buttons--secondary" aria-selected="true">1</button>
    <button class="o-buttons o-buttons--secondary">2</button>
    <button class="o-buttons o-buttons--secondary">3</button>

    <button class="o-buttons o-buttons--secondary o-buttons-icon o-buttons-icon--arrow-right o-buttons-icon--icon-only">
        <span class='o-buttons-icon__label'>More results</span>
    </button>
</div>

Disabled

o-buttons styles buttons with the disabled attribute to show they are inactive. In some cases it is preferred to visually hide the button until it is active. For this case add the class o-buttons--hide-disabled.

<!-- Visibly disabled because of the `disabled` attribute. -->
<button class="o-buttons" disabled>My Button</button>

<!-- Visually hidden because of the `disabled` attribute and `o-buttons--hide-disabled`.-->
<button class="o-buttons o-buttons--hide-disabled" disabled>My Button</button>

Sass

To output default o-buttons CSS make a single call to the primary mixin oButtons. It is recommended that you pass an options map as the first argument to include only the button styles you need. Without the options map, all o-buttons styles are included.

@mixin oButtons($opts: (
    'sizes': ('big'), // e.g .o-buttons--big
    'types': ('primary', 'secondary'), // e.g .o-buttons--primary
    'themes': ('mono', 'inverse', 'b2c'), // e.g .o-buttons--inverse
    'icons': ('arrow-left', 'arrow-right', 'search'), // any fticons, e.g .o-buttons-icons.o-buttons-icons--search
    'pagination': true, // .o-buttons-pagination
    'groups': true // .o-buttons-group
));

Custom Themes

To create a new button theme call oButtonsAddTheme with the colour of your theme along with the types of buttons and icons you would like to use with your theme, if any.

/// .o-buttons--my-special-button
@include oButtonsAddTheme(
    $name: 'my-special-button',
    $opts: ('color': 'claret-80'),
    $types: ('primary', 'secondary'),
    $icons: ('arrow-up', 'arrow-down')
);

Custom Markup

We recommend using o-buttons markup as this encourages CSS reuse and smaller bundle sizes. If you are unable to update your markup to use o-buttons classes, including those generated by oButtonsAddTheme, use oButtonsContent:

.my-button {
    @include oButtonsContent($opts: ('type': 'primary'));
}
.my-icon-button {
    @include oButtonsContent($opts: (
        'type': 'primary',
        'icon': 'arrow-right'
    ));
}
.my-lemon-button {
    @include oButtonsContent($opts: (
        'type': 'primary',
        'theme': ('color': 'lemon')
    ));
}

oButtonsContent has options to recreate all buttons, including for different sizes and icon only buttons. See the o-buttons SassDoc for more details and examples.
