Please review the design of our coffee shop landing page at file:///ABS/sample/index.html (the file is .claude/skills/web-design-reviewer/sample/index.html in the current directory) at a desktop width (1280x800) and a mobile width (375x800). You have no browser tool, but you may take screenshots by running exactly: `sh .claude/skills/web-design-reviewer/shot.sh "file://$PWD/.claude/skills/web-design-reviewer/sample/index.html" <width> <height> .claude/skills/web-design-reviewer/shots/<name>.png` and then open the PNG with Read. You cannot edit files in this environment, so do the inspection and report only (list the issues with severity and the fix you would make in the source), following the skill's report format.

Detected Issues

[P1] Cards overflow the viewport on mobile

  • Page: /
  • Element: .cards and .card (index.html:11-12)
  • Issue: Each card is a fixed 320px with flex:none in a non-wrapping row. At 375px only the first card is visible and it is clipped on the right. The other two cards are off-screen and the page scrolls sideways. The hero heading and paragraph are also cut off at the right edge, which suggests the page is wider than the viewport.
  • Fix:
    .cards{display:grid;grid-template-columns:repeat(auto-fit,minmax(260px,1fr));gap:24px;padding:32px 16px}
    .card{border:1px solid #ddd;padding:16px}  /* drop width:320px and flex:none */
    
    Alternatively, keep flex and use flex-wrap:wrap with .card{flex:1 1 260px}.

[P1] Hero paragraph has insufficient contrast

  • Element: .hero p (index.html:9)
  • Issue: #c9b9a6 on #f3e9dc is about 1.6:1, against the 4.5:1 AA requirement. The text is nearly unreadable.
  • Fix: color:#5a4636, which is about 7:1 on the hero background.

[P1] Price badges are positioned fragilely and overlap

  • Element: .price (index.html:15)
  • Issue: The badge uses position:absolute with hard-coded margin-top:-40px and margin-left:200px. It has no positioned ancestor, so it floats at an arbitrary spot. It sits beside the title instead of at a deliberate corner. On narrower cards it would collide with the title or fall outside the card.
  • Fix:
    .card{position:relative}
    .price{position:absolute;top:24px;right:24px;margin:0;...}
    
    Or put the title and price in a flex row with justify-content:space-between.

[P1] "Order now" CTA is too small

  • Element: .cta (index.html:10)
  • Issue: The button has 11px text and 4px/8px padding, so it is about 20px tall. That is far below the 44×44px touch target, and it is the page's primary action. White on #8a5a2b has acceptable contrast, at about 5.5:1.
  • Fix: padding:12px 24px;font-size:16px;min-height:44px;border-radius:4px.

[P2] Missing image alt text and broken images

  • Element: .card img (index.html:21-23)
  • Issue: The images have no alt attribute. x.png also fails to load, so a broken-image icon shows on a grey block.
  • Fix: Add descriptive alt text, for example alt="House Blend coffee bag", and point src at real assets. Add object-fit:cover to .card img.

[P2] No focus or hover states

  • Element: header a, .cta
  • Issue: No :focus-visible or :hover styles are defined. Keyboard users get only the browser default, which is hard to see on the dark header. The nav links also have no hover feedback.
  • Fix:
    a:focus-visible{outline:3px solid #f5a623;outline-offset:2px}
    header a:hover,.cta:hover{text-decoration:underline}
    

[P2] Card headings use a different font

  • Element: .card h3 (index.html:14)
  • Issue: The headings are Arial sans-serif, while the rest of the page is Georgia serif. The mix looks accidental.
  • Fix: Remove the font-family override, or apply one deliberate heading font to every heading, including h1.

[P3] Smaller polish items

  • Nav on mobile: The three links fit at 375px, but they are about 20px tall and sit close together. Add padding:12px 0 to the links. Consider flex-wrap:wrap, because more items will break the header.
  • Footer text: At 13px it is small. Use at least 14px.
  • Layout width: No max-width or centering. At 1280px the cards leave empty space on the right, and wider screens will look unbalanced. Wrap the content in a container with max-width:1100px;margin:auto.
  • Hero heading: Use font-size:clamp(28px,6vw,44px) so it scales on small screens.
  • Document title: <title>Brew & Co</title> has an unescaped &. Use &amp;.

Unfixed Issues

All of the above are unfixed because this environment is read-only. The fixes are listed per issue.

Recommendations

  • Apply the P1 fixes first, then re-screenshot at 375, 768 and 1280, and add 1920 to check the max-width behavior.
  • Move the colors into CSS custom properties (for example --brown, --cream) so contrast is easy to keep consistent.
  • Add a tablet check at 768px. The card grid fix should give two columns there, but I haven't verified it.
  • My first screenshot call was blocked by the sandbox's command check. Re-running the two screenshot commands separately worked.

试用方式:这是“部分试用”。试用环境没有浏览器工具,所以我提供了一个只会用无头 Chrome 截图的脚本,模型用它截图并用 Read 看图;我做了一个有 8 处故意缺陷的静态页面。试用环境不能改文件,所以只做了检查和报告,没有做修改源码并复查。我复算了对比度(1.6:1 和修复后约 7:1)与报告一致。

What it does

Looks at a website running locally, on staging or in production (read-only) through browser automation, finds visual problems and fixes them in your source. It checks element overflow and overlap, alignment and spacing, text clipping, mobile layouts, touch targets, contrast, focus states, alt text, and font and colour consistency at four viewports (375, 768, 1280 and 1920 px). It detects your framework and styling method (plain CSS, SCSS, CSS Modules, Tailwind, styled-components and others) and has a fix guide for each.

How it works

  1. It confirms the URL and detects the project and styling method.
  2. It captures screenshots and the DOM, rates issues P1 to P3 and traces them to source files.
  3. It applies the smallest fix, reloads, compares before and after, and repeats; after three failed attempts on one issue it asks you.
  4. It writes a report with detected, fixed and unfixed issues.

Good for

Cleaning up layout and responsive bugs and doing a visual pass before release.

Notes & risks

Medium risk: it edits existing source files (styles and components) in your project, so commit or back up first and review the diff. Its own rules limit it to minimal changes, require following your code style, say to confirm before major changes and to treat production as read-only. It needs browser automation (the skill suggests the Playwright MCP, started with `npx -y @playwright/mcp@latest`, which downloads and runs a package) and visits whatever URL you give it. Partly test-run: only the inspect-and-report half. I made a page with 8 planted defects and used headless Chrome screenshots instead of Playwright; the model found all of them at desktop and mobile widths (card overflow, 1.6:1 contrast, tiny button, missing alt, font mix, overlapping badge and more), and I recomputed its contrast figures and fixes as correct. The edit-source-and-recheck half was not tried, and the Playwright MCP was not used.
