:valid Back

• :valid is a CSS pseudo-class used to select and style form <input> elements whose values validate according to their type specified in the type attribute.
• For example, email inputs (<input type="email">) whose values match a valid email address pattern.

Note

• When a number input type (<input type="number">) is in the range of permitted values specified using the min and max attributes, then the :valid pseudo-class matches, and also the :in-range pseudo-class matches.
• Any styles applied using :in-range will override the styles applied using :valid only if the :in-range styles come after the :valid styles in the style sheet.
