💡 Hint

Common Mistakes

Forgetting bind:value causes no reactive updates.

Not using aria-label reduces accessibility.

Leaving placeholder empty makes the input less user-friendly.

Use bind:value to connect the input value to email. The aria-label improves accessibility by describing the input. The placeholder shows a hint inside the input.
