Form Accessibility

4 of 10 controls have issues

4 control(s) without accessible label
Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

Why this matters

Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

Skip navigation link is missing (WCAG 2.4.1)

Page Structure — as a screen reader sees it
BANNER header NAV "aalto-topnav-button-text" MAIN CONTENTINFO footer

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.

Why this matters

Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.
