In this part we will consider the native error messages and offer general recommendations to come to actually usable native form validation.

Native form validation 1: UI and CSS

Permalink | in Coding techniques

After doing exhaustive research into modern CSS and JavaScript form validation, I present my conclusions in this series of articles. It will discuss HTML validation messages, the CSS :invalid and :valid pseudo-classes, and the Constraint Validation API that is supposed to make form validation easier but doesn’t really.

In this article we will attempt to validate a form in a user-friendly fashion entirely by using existing native HTML, CSS, and JavaScript features, writing a few very light custom scripts to pull some supposedly-easy strings in the Constraint Validation API.
