Cross Browser Form Validation

Form validation is the method of setting required fields and field types without requiring JavaScript. This includes preventing forms from being submitted when appropriate, the `checkvalidity()` method as well as support for the `:invalid`, `:valid`, and `:required` css pseudo-classes.

Browser Support

This feature is already supported by a few major browsers including Chrome, Firefox, Internet Explorer 11, Microsoft Edge and Opera.

Code Example

You can use Form validation like this:

<input type="email" name="email" required placeholder="Enter a valid email address">
