141 links and buttons have descriptive text

Generic link text like 'click here' doesn't describe the destination.

https://aka.ms/MS_Build_FY26_dotnet ("Learn more")

Why this matters

Generic anchor text ('click here', 'read more', 'learn more') tells screen readers and search engines nothing about the destination.

Learn more ▾

Out-of-context lists of links read by AT (one navigation pattern) become useless when every link says 'click here'. Use the destination's title or topic as anchor text. Doubles as SEO win — Google passes anchor-text relevance to the destination.

Why this matters

Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.

Learn more ▾

Without rel="noopener", the new tab can navigate the original tab via window.opener (tab-nabbing attack). Modern browsers default to noopener for target=_blank but only since recent versions. Always set rel="noopener noreferrer" explicitly.

Landmark Structure

9 landmarks

PASS

9 landmarks

<main> landmark present

4 <nav> landmark(s) found

1 of 4 <nav> elements are unlabeled

Multiple navigations need aria-label to distinguish them for screen readers.

Skip navigation link present

Page Structure — as a screen reader sees it

Multiple navigations need aria-label to distinguish them for screen readers.

Why this matters

Some <nav> elements lack aria-label — screen-reader users hear 'navigation' multiple times with no way to distinguish them.

Learn more ▾

When a page has multiple <nav> regions (primary, footer, breadcrumb), each needs aria-label or aria-labelledby. AT users navigate by landmark; identical 'navigation' announcements force them to enter each one to discover purpose.

Form Accessibility

1 of 2 controls have issues

PASS

1 of 2 controls have issues

1 control(s) rely on placeholder only

Placeholder text disappears on focus and is not a reliable label.

Got: <input type="search" name="q">

1 control(s) properly labeled

2 controls

1 labeled

1 placeholder only

0 unlabeled

Control	Type	Label	Method
#culture-options	select	Change language	aria-label
q	search	(Search or ask a question)	placeholder only

Placeholder text disappears on focus and is not a reliable label.

Why this matters

Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.

Learn more ▾

Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).

Lighthouse Accessibility Audits

Score 97/100 — 1 failing, 27 passed

PASS

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

Best practices

Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.

Why this matters

Performance issues directly impact user engagement and conversion rates.
