How can you style a form field differently when focused and valid?

Q: How can you style a form field differently when focused and valid?

You can use the `:focus` and `:valid` pseudo-classes together to style form fields based on their state. The `:focus` pseudo-class applies styles when a field is active (clicked or selected), while `:valid` applies when the field’s input satisfies its validation rules. `:focus` targets form fields that are currently active or being edited by the user. `:valid` targets fields whose values meet validation criteria, such as matching a pattern or not being empty when `required`. You can combine them as `input:focus:valid` to apply styles only when both conditions are true. /* Base input style */ input { border: 2px solid #ccc; padding: 8px; border-radius: 4px; outline: none; } /* Highlight when focused */ input:focus { border-color: dodgerblue; } /* Highlight when valid */ input:valid { border-color: green; } /* Combine focus and valid states */ input:focus:valid { background-color: #e6ffe6; } Email: In this example, when the user clicks the input field, it gets a blue border due to `:focus`. Once a valid email is entered, the border turns green. When both focused and valid, the input background changes to light green. Use `:focus` and `:valid` to give users clear visual feedback on form interactions. Combine pseudo-classes like `:focus:invalid` for error highlighting. Ensure validation rules (like `type` or `pattern`) are properly set in HTML. Maintain accessibility by ensuring color changes have sufficient contrast.
