Variants

Use the variant attribute to set the button’s variant. Primary, sceondary and teriary are the core button variants. Use the primary button to call attention to an action on a form or highlight the strongest call to action on a page. Primary buttons should only appear once per container. Use the Use tertiary buttons where a group of buttons is needed.

Primary Secondary Tertiary Naked
On Dark
On Light Extra 
<sl-button variant="primary">Primary</sl-button>
<sl-button variant="secondary">Secondary</sl-button>
<sl-button variant="tertiary">Tertiary</sl-button>
<sl-button variant="naked">Naked</sl-button>
<div style="background: var(--hds-color-bg-primary, #283D84); display: inline-flex; padding: 5px;">
  <sl-button variant="on-dark">On Dark</sl-button>
</div>
<sl-button variant="on-light">On Light</sl-button>
<sl-button variant="extra">Extra</sl-button>

Contextual variants

Use contextual buttons when appropriate to call attention to an action.

Neutral Success Warning Danger 
<sl-button variant="neutral">Neutral</sl-button>
<sl-button variant="success">Success</sl-button>
<sl-button variant="warning">Warning</sl-button>
<sl-button variant="danger">Danger</sl-button>

Sizes

Use the size attribute to change a button’s size, which affects its height and text size. There are three available sizes: small, medium (default), and large.

Small Medium Large 
<sl-button size="small">Small</sl-button>
<sl-button size="medium">Medium</sl-button>
<sl-button size="large">Large</sl-button>

Outline buttons

Use the outline attribute to draw outlined buttons with transparent backgrounds.

Primary Neutral Success Warning Danger 
<sl-button variant="primary" outline>Primary</sl-button>
<sl-button variant="neutral" outline>Neutral</sl-button>
<sl-button variant="success" outline>Success</sl-button>
<sl-button variant="warning" outline>Warning</sl-button>
<sl-button variant="danger" outline>Danger</sl-button>

Pill buttons

Use the pill attribute to give buttons rounded edges.

Small Medium Large 
<sl-button size="small" pill>Small</sl-button>
<sl-button size="medium" pill>Medium</sl-button>
<sl-button size="large" pill>Large</sl-button>

Minimum Width

Each button size has a minimum width to help accommodate a balanced look for shorter labels. It can be turned on or off at project level.

  • Small buttons: 64px minimum width
  • Medium buttons: 80px minimum width
  • Large buttons: 104px minimum width These minimum widths ensure buttons maintain a consistent appearance when used with short labels.

Buttons with Icons

Icons can be added to buttons using the prefix and suffix slots. It’s recommended to use only one icon per button.

Back Next Back Next 
<div style="display: flex; flex-direction: column; gap: 1rem;">
  <div style="display: flex; gap: 1rem;">
    <sl-button size="small">
      <sl-icon slot="prefix" name="arrow-left"></sl-icon>
      Back
    </sl-button>
    <sl-button size="small">
      Next
      <sl-icon slot="suffix" name="arrow-right"></sl-icon>
    </sl-button>
      <sl-button size="medium">
      <sl-icon slot="prefix" name="arrow-left"></sl-icon>
      Back
    </sl-button>
    <sl-button size="medium">
      Next
      <sl-icon slot="suffix" name="arrow-right"></sl-icon>
    </sl-button>
  </div>
</div>

Icon buttons

Use the icon attribute to create circular icon buttons. When this attribute is set, the button expects a single <sl-icon> in the default slot. 

<sl-button variant="secondary" size="small" icon>
  <sl-icon name="gear" label="Settings"></sl-icon>
</sl-button>

<sl-button variant="secondary" size="medium" icon>
  <sl-icon name="gear" label="Settings"></sl-icon>
</sl-button>

<sl-button variant="secondary" size="large" icon>
  <sl-icon name="gear" label="Settings"></sl-icon>
</sl-button>

Opacity text buttons

Use the dark or light variant to create text buttons that share the same size as regular buttons but don’t have backgrounds or borders. Dark or Light use opacity and are for use on colored backgrounds.

Dark Light 
<div style="background: grey">
  <sl-button variant="dark" size="medium">Dark</sl-button>
  <sl-button variant="light" size="medium">Light</sl-button>
</div>

It’s often helpful to have a button that works like a link. This is possible by setting the href attribute, which will make the component render an <a> under the hood. This gives you all the default link behavior the browser provides (e.g. CMD/CTRL/SHIFT + CLICK) and exposes the target and download attributes.

Link New Window Download Disabled 
<sl-button href="https://example.com/">Link</sl-button>
<sl-button href="https://example.com/" target="_blank">New Window</sl-button>
<sl-button href="/assets/images/wordmark.svg" download="shoelace.svg">Download</sl-button>
<sl-button href="https://example.com/" disabled>Disabled</sl-button>

Setting a custom width

As expected, buttons can be given a custom width by setting the width attribute. This is useful for making buttons span the full width of their container on smaller screens.

Full Width Small Full Width Medium Full Width Large
200px Width 
<!-- Full-width buttons -->
<sl-button style="--width: 100%; margin-bottom: 1rem;" variant="secondary" size="small">Full Width Small</sl-button>
<sl-button style="--width: 100%; margin-bottom: 1rem;" variant="secondary" size="medium">Full Width Medium</sl-button>
<sl-button style="--width: 100%; margin-bottom: 1rem;" variant="secondary" size="large">Full Width Large</sl-button>

<!-- Custom width buttons -->
<div style="margin-top: 1rem;">
  <sl-button style="--width: 200px;" variant="primary">200px Width</sl-button>
</div>

Prefix and suffix icons

Use the prefix and suffix slots to add icons.

Caret

Use the caret attribute to add a dropdown indicator when a button will trigger a dropdown, menu, or popover.

Small Medium Large 
<sl-button size="small" caret>Small</sl-button>
<sl-button size="medium" caret>Medium</sl-button>
<sl-button size="large" caret>Large</sl-button>

Loading

Use the loading attribute to make a button busy. The width will remain the same as before, preventing adjacent elements from moving around.

<sl-button variant="danger" loading>Danger</sl-button>

Disabled

Use the disabled attribute to disable a button.

Styling buttons

This example demonstrates how to style buttons using a custom class. This is the recommended approach if you need to add additional variations. To customize an existing variation, modify the selector to target the button’s variant attribute instead of a class (e.g. sl-button[variant="primary"]).

Pink Button 
<sl-button class="pink">Pink Button</sl-button>

<style>
  sl-button.pink::part(base) {
    /* Set design tokens for height and border width */
    --sl-input-height-medium: 48px;
    --sl-input-border-width: 4px;

    border-radius: 0;
    background-color: #ff1493;
    border-top-color: #ff7ac1;
    border-left-color: #ff7ac1;
    border-bottom-color: #ad005c;
    border-right-color: #ad005c;
    color: white;
    font-size: 1.125rem;
    box-shadow: 0 2px 10px #0002;
    transition: var(--sl-transition-medium) transform ease, var(--sl-transition-medium) border ease;
  }

  sl-button.pink::part(base):hover {
    transform: scale(1.05) rotate(-1deg);
  }

  sl-button.pink::part(base):active {
    border-top-color: #ad005c;
    border-right-color: #ff7ac1;
    border-bottom-color: #ff7ac1;
    border-left-color: #ad005c;
    transform: scale(1.05) rotate(-1deg) translateY(2px);
  }

  sl-button.pink::part(base):focus-visible {
    outline: dashed 2px deeppink;
    outline-offset: 4px;
  }
</style>

disabled Disables the button. boolean false
loading Draws the button in a loading state. boolean false
outline Draws an outlined button. boolean false
pill Draws a pill-style button with rounded edges. boolean false
icon Draws a circular icon button. When this attribute is present, the button expects a single <sl-icon> in the default slot. boolean false
type The type of button. Note that the default value is button instead of submit, which is opposite of how native <button> elements behave. When the type is submit, the button will submit the surrounding form. 'button' | 'submit' | 'reset' 'button'
name The name of the button, submitted as a name/value pair with form data, but only when this button is the submitter. This attribute is ignored when href is present. string ''

target Tells the browser where to open the link. Only used when href is present. '_blank' | '_parent' | '_self' | '_top' -
rel When using href, this attribute will map to the underlying link’s rel attribute. Unlike regular links, the default is noreferrer noopener to prevent security exploits. However, if you’re using target to point to a specific tab/window, this will prevent that from working correctly. You can remove or change the default value by setting the attribute to an empty string or a value of your choice, respectively. string 'noreferrer noopener'
download Tells the browser to download the linked file as this filename. Only used when href is present. string | undefined -
form The “form owner” to associate the button with. If omitted, the closest containing form will be used instead. The value of this attribute must be an id of a form in the same document or shadow root as the button. string -
