attribute helped inform users which fields were required, while pattern
allowed developers to provide a regular expression to match against an <input>
's value. Targeting required fields and validation values with just CSS and HTML was very useful.

to allow you to style form elements that aren't required?
input:optional, select:optional, textarea:optional {
border: 1px solid #eee;
}
[required] {

}
In a sense, it feels like :optional
represents :not([required])
, but :optional
is limited to just form fields.
