String | A value of text aligns the leading edge of text |

The implementation of the d2l-more-less component follows the W3C Disclosure (Show/Hide) Pattern. It is worth noting that the content that is visually hidden is not actually hidden from screen reader users since those users can interrupt the screen reader if they do not want to continue listening to the content.
