Can I use input:active without selecting an attribute? If not, why not?

Does selecting a type attribute just make my rule more specific? If so, shouldn't I make the rule even more specific by adding a class? Is adding a class not necessary because there is only one submit button on the page?

Thank you in advance! I realize there are a lot of questions here.

A class rule has higher specificity than a type (tag/attribute) rule. But a better way to select a unique element might be using an ID, and an ID rule has even higher specificity than a class rule.

For more details, see the MDN page on CSS Specificity.
