## Accessibility Audit of expressjs.com
I ran an accessibility scan on https://expressjs.com and found a few issues that could affect users who rely on assistive technologies. The site is in good shape overall — here are the remaining items.
**Overall Score: 84/100 (Grade B)**
**Failed Checks: 3 of 16**
---
### 1. Missing Form Label on Search Input (HIGH severity)
**WCAG: SC 1.3.1 Info and Relationships (Level A), SC 4.1.2 Name, Role, Value (Level A)**
The search input has an `id` but no associated `<label>`, `aria-label`, or `title`. Screen reader users cannot identify the purpose of this input.
**Affected element:**
```html
<input id="q" placeholder="🔎 search">
```
**Fix — Option A (aria-label, minimal change):**
```html
<input id="q" placeholder="🔎 search" aria-label="Search Express documentation">
```
**Fix — Option B (associated label):**
```html
<label for="q" class="sr-only">Search Express documentation</label>
<input id="q" placeholder="🔎 search">
```

### 2. No Skip Navigation Link (MEDIUM severity)
**WCAG: SC 2.4.1 Bypass Blocks (Level A)**
No "Skip to main content" link found. Keyboard-only users must tab through the full navigation on every page to reach content.
**Fix:** Add a skip link as the first focusable element:
```html
<body>
<a href="#main" class="skip-link">Skip to main content</a>
<!-- existing nav -->
<main id="main">
```
With CSS:
```css
.skip-link {
position: absolute;
top: -40px;
left: 0;
padding: 8px;
background: #000;
color: #fff;
z-index: 100;
}
.skip-link:focus {
top: 0;
}
```

### 3. One Link Missing Accessible Text (MEDIUM severity)
**WCAG: SC 2.4.4 Link Purpose (In Context) (Level A)**
The Netlify sponsor link in the footer wraps an image but has no `aria-label`.
**Affected element:**
```html
<a href="https://www.netlify.com">
<img src="https://www.netlify.com/v3/img/components/netlify-color-accent.svg" alt="Preview Deploys by Netlify" width="80" />
</a>
```
**Fix:** Add `aria-label`:
```html
<a href="https://www.netlify.com" aria-label="Netlify - Preview Deploys">
<img src="https://www.netlify.com/v3/img/components/netlify-color-accent.svg" alt="Preview Deploys by Netlify" width="80" />
</a>
```
