Props

When setting props as attributes on a custom HTML element, use kebab-case instead of camelCase.

Prop	Type	Validation	Default	Description
`additionalClass`	String	—	—	A space-separated list of class names that will be appended to the default `mds-form__microcopy` class.
`id`	String	Required	—	The `id` attribute for the HTML element.
`size`	String	One of: `small`, `medium`, `large`	`medium`	Alters the size of the microcopy.
`text`	String	Required	—	The text for the microcopy. Can also be passed via the default slot.

Slots

Default Slots

Pass text in between the <mds-microcopy></mds-microcopy> tags to set the microcopy’s text content. This can be overridden with the text prop.

Usage Examples

Setting id and size via props. Using the default slot for text content:

<mds-microcopy id="microcopy-id" size="small">
    Your password must contain a letter and a number.
</mds-microcopy>

Implementation

Include an aria-describedby attribute on each input, textarea, or select that has an .mds-form__microcopy component providing additional information. The value of the aria-describedby attribute must match the id attribute on the .mds-form__microcopy component.
