Forms suck.
They are incredibly tedious to create.
They are undeniablyannoying to fill in.
They can be frustrating to test.
They require logic.
Forms suck.
Forms suck.can
Forms suck.don’t have to
Forms suck.can
a lot less
Forms can be… easy to build predictable
effortless to use and accessible
It’s all in how you look at them.

Ok, I get it: forms in HTML5 are awesome.
But how should we organize our forms?
FALLING IN LOVE WITH FORMS
Do we divide it up?
<div> <label for=“full_name”>Your Name</label> <input id=“full_name” name=“full_name” required> </div>

Do paragraphs make sense?
<p> <label for=“full_name”>Your Name</label> <input id=“full_name” name=“full_name” required> </p>
FALLING IN LOVE WITH FORMS
Is it a list of questions?
<ol> <li> <label for=“full_name”>Your Name</label> <input id=“full_name” name=“full_name” required> </li> </ol>
