:optional CSS Pseudo Class
Description
The :optional
pseudo-class applies style rules to the <input>
element, which does not have the required attribute set; it allows you to select required fields before submitting the form. Thus :optional
applies to optional form fields.
Syntax
input:optional { ... }
Example
<p>Please enter your name and age.</p>
<p>Name: <input name="name" required ></p>
<p>Age: <input type="number" name="old"> (Optional)</p>
<p><button>Submit</button></p>
input:optional {
border:1px dashed green;
}
