**Summary:**
As we start working on {T415659} we'd like to rely on existing Codex components and validation props to enable us to run experiments in the account creation space.
This task involves updating the Special:CreateAccount page to use Codex Field components that come with built-in props and validation messaging capabilities.
**Background:**
This work establishes the foundation needed to experiment with:
* Feedback patterns during account registration
* Interaction patterns for form validation
* How the system communicates with and guides people registering on Wikipedia
By implementing Codex Field components with inline validation messages, we'll have a flexible base for testing different approaches to user guidance and error messaging in the account creation flow.
**Design:**
| Before | After |
| --- | --- |
| {F71701239} | {F71701374} |
| {F71701410} | {F71701299} |
####Acceptance Criteria:
- [ ] Special:CreateAccount uses Codex Field components for form inputs
- [ ] Validation messages use Codex inline Message component
- [ ] Component implementation supports experimentation with different validation patterns and messaging
- [ ] In addition to changing the dynamically added created messages, it is also approved to change the way errors messages are displayed in HTMLForm in general.
