title: Scroll to the first input error of HTML5 form validation
body: <p>I have a long form with submit button at the bottom of the form. I have multiple input fields in the form marked with required attribute. So when one of the first few input fields are left blank and I scroll down to click submit, the error "Please fill out this field" came out correctly for the first error on top of the browser. However, I have to scroll up all the way to the top to enter the input. How can I make it automatically scroll up to focus on the first input error?</p>
