+description: Always-rendered error paragraphs with min-height prevent layout shift when errors appear
+type: feedback
+---
+
+Always-rendered `<p class="error">{error}</p>` elements with `min-height: 1.4em` are intentional — they reserve space so surrounding elements don't shift when an error message appears.
+
+**Why:** Layout stability during form validation feedback.
+
+**How to apply:** Do not suggest wrapping these in `{#if error}` or removing the `min-height`. This is a deliberate UX choice, not an oversight.
