You built the form, tested it on your desktop, shipped it to production. Then the support tickets start rolling in: "I can't tap the submit button," "the dropdown is cut off," "I can't see what I'm typing." You open the form on your phone and watch in horror as fields overlap, buttons disappear, and your carefully designed layout crumbles.
"Show this field only if the user selects 'Other'." Simple requirement, right? Fast forward three months and your form has 47 conditional rules, nested five levels deep, and nobody remembers why field 23 disappears when you select "Business" in the account type dropdown.
You fix one validation bug and two more pop up. The phone number format works for US numbers but breaks for international. The email regex rejects valid addresses. Max length validation conflicts with the paste handler. Welcome to validation whack-a-mole—the game nobody wins.
Every developer knows the feeling: you need "just a simple form" and suddenly you're three days deep in HTML, CSS, JavaScript, accessibility requirements, and edge cases you never anticipated. Building forms from scratch has become an industry-wide boss fight that consumes far more resources than it should.
