Button
Buttons represent actions that are available to the user.
<pc-button>Button</pc-button>
Demos
Appearances
Use the appearance
attribute to set the button’s appearance.
Sizes
Use the size
attribute to change the button’s size.
Outlined
Use the outlined
attribute to draw outlined buttons with transparent backgrounds.
Pill
Use the pill
attribute to give buttons a pill‐shaped look.
Links
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 as an <a>
under the hood. This gives you all the default link behaviour the browser provides (e.g., or Shift + target
and download
attributes.
When a target
is set, the link will receive rel="noreferrer noopener"
for security reasons.
Custom width
As expected, buttons can be given a custom width by passing inline styles to the component (or using a class). This is useful for making buttons span the full width of their container on smaller screens.
Prefixes and suffixes
Use the prefix
and suffix
slots to add icons.
Disabled
Use the disabled
attribute to disable a button.
Custom styles
This example demonstrates how to style buttons using a custom class. This is the recommended approach if you need to add additional appearances. To customise an existing appearance, modify the selector to target the button’s appearance
attribute instead of a class (e.g., pc-button[appearance="primary"]
).
Properties
Name | Description | Reflects | Default |
---|---|---|---|
appearance | The button’s appearance. "default"
| "primary"
| "success"
| "warning"
| "danger"
| "text" | "default" | |
size | The button’s size. "small" | "medium" | "large" | "medium" | |
disabled | Disables the button. boolean | false | |
outlined | Draws an outlined button. boolean | false | |
pill | Draws a pill‐style button. 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. string | "" | |
value | The value of the button, submitted as a pair with the button’s name as part of the form data, but only when this button is the submitter. This attribute is ignored when the href attribute is present. string | "" | |
href | When set, the underlying button will be rendered as an <a> with this href instead of a <button> . string | "" | |
target | Tells the browser where to open the link. It should only be used when the href attribute is present. "_blank" | "_parent" | "_self" | "_top" | undefined | - | |
rel | When using the href attribute, this attribute will map to the underlying link’s rel attribute. Unlike regular links, the default set for this attribute is noreferrer noopener to prevent security exploits. However, if you’re using target to point to a specific tab or window, this will prevent that from working properly. 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 file name. Only used when the href attribute is present. string | undefined | - | |
form | This is 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 | undefined | - | |
formAction formaction | Used to override the form owner’s action attribute. string | undefined | - | |
formEnctype formenctype | Used to override the form owner’s enctype attribute. "application/x-www-form-url-encoded"
| "multipart/form-data"
| "text/plain" | undefined | - | |
formMethod formmethod | Used to override the form owner’s method attribute. "GET" | "POST" | undefined | - | |
formNoValidate formnovalidate | Used to override the form owner’s novalidate attribute. boolean | undefined | - | |
formTarget formtarget | Used to override the form owner’s target attribute. "_self"
| "_blank"
| "_parent"
| "_top"
| string | undefined | - | |
