Q: What does :read-only and :read-write do?

The `:read-only` and `:read-write` pseudo-classes in CSS allow you to style form elements based on their editability state. They help indicate to users whether an input can be modified or is read-only. `:read-only` – Selects form elements that are not editable (e.g., elements with the `readonly` attribute). `:read-write` – Selects form elements that are editable and can be changed by the user. These pseudo-classes dynamically reflect the current state of the element. /* Style read-only inputs */ input:read-only { background-color: #f0f0f0; border: 1px dashed gray; } /* Style editable inputs */ input:read-write { background-color: #ffffff; border: 1px solid black; } Editable Input: Read-Only Input: In this example, the editable input has a white background with a solid border, while the read-only input has a gray background and dashed border, clearly indicating which fields can be modified. Use `:read-only` and `:read-write` to provide visual feedback about editable states of form elements. Combine with `:focus` or `:hover` to enhance interactivity and UX. Ensure visual cues are accessible and distinguishable, not relying solely on color. Test behavior across different browsers and input types to ensure consistent styling.
