| `.k-prompt-box-singleline .k-prompt-box-input` | `nodeName=input` | Ensures the input field has the proper textbox role. |
|  | `aria-label` or `aria-labelledby` | Provides an accessible label for the input. Use `aria-label` or associate with a visible label via `aria-labelledby`. |
|  | `placeholder` | Provides a short hint to the user about the expected input. Should not replace proper labeling. |

#### Multi-line Textarea

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| `.k-prompt-box-multiline .k-prompt-box-textarea` | `nodeName=textarea` | Ensures the textarea has the proper textbox role. |
