The Coding Machine

What Dr Urls found on thecodingmachine-lyon.fr

From the audit of their public home page on 08/11/2026, worst first. Each links to what it means and how it is fixed.

• medium
  Icon-only button missing aria-label

  Icon-only buttons are extremely common in modern UIs (hamburger menus, close buttons, search icons), but without aria-labels, they are completely opaque to screen reader users.

• medium
  Images missing width and height attributes

  Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.

• medium
  Nested interactive elements detected

  Nested interactive elements produce unpredictable behavior across browsers and assistive technologies.

• medium
  Render-blocking CSS or JavaScript

  Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.

• medium
  Scripts without async or defer

  Synchronous scripts halt HTML parsing while the browser downloads and executes them.

• low
  Below-the-fold images not lazy loaded

  Loading all images immediately increases initial page weight and competes with critical resources for bandwidth.

• low
  Broken heading hierarchy

  Heading hierarchy provides a semantic outline of the page content.

• low
  Excessive inline CSS

  Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.

• low
  H1 heading is too long

  A concise H1 provides a clear, focused signal about the page's primary topic.

• low
  Image has empty alt attribute

  If a content-relevant image has an empty alt attribute, search engines cannot understand what the image depicts, and it will not appear in image search results.

• low
  Images missing responsive srcset

  Without srcset, a 1200px wide image is downloaded on a 375px wide mobile screen, wasting bandwidth and slowing load times.

• low
  Images not using modern format

  WebP images are 25-35% smaller than equivalent JPEG images, and AVIF offers even greater savings.
