Forms suck.

They are incredibly tedious to
create.

They are undeniably annoying to
fill in.

They can be frustrating to
test.

They require logic.

Forms suck.

Forms suck.

Forms suck.

Forms suck. can a lot

Forms can be… easy to
build predictable effortless to use and accessible

It’s all in how you
look at them.

HELPFUL HINT Break large, complex
forms into smaller, simpler, reusable patterns

Ok, I get it: forms
in HTML5 are awesome. But how should we organize our forms?

Do we divide it up? <div> <label for=“full_name”>Your Name</label> <input id=“full_name” name=“full_name” required> </div>
