annoying to fill in.
They can be
frustrating to test.
They require logic.

Forms can be…

and accessible
It’s all in how you
look at them.

Without forms, the web would not be what it is today, but they are challenging from a markup and styling standpoint. In this session, we'll explore forms from top to bottom, examining how they work and how their components can be incorporated with other elements to maximize accessibility, improve semantics, and allow for more flexible styling. You’ll get to see the complete picture with forms, including new HTML5 field types; validation, error messages & formatting hints; how to mark up and style forms for the greatest flexibility in responsive designs; and best practices for enhancing forms with JavaScript. By the end of this session you’ll be prepared to tackle whatever form-related challenges are thrown at you. You might even find yourself a little giddy over how awesome you can make them.
