-### Input Highlight
-
-Items containing an input will highlight the bottom border of the input with a different color when focused, valid, or invalid. By default, `md` items have a highlight with a height set to `2px` and `ios` has no highlight (technically the height is set to `0`). The height can be changed using the `--highlight-height` CSS property. To turn off the highlight, set this variable to `0`.
-
-The highlight color changes based on the item state, but all of the states use Ionic colors by default. When focused, the input highlight will use the `primary` color. If the input is valid it will use the `success` color, and invalid inputs will use the `danger` color. This can be customized using the provided CSS properties.

+Label is an element used primarily to add text content to [Item](./item.md) components. Label can also be used inside of form control components such as [Input](./input.md) or [Radio](./radio.md) when specifying the visible label, but it is not required.
