What Dr Urls found on javierchiva.com

From the audit of their public home page on 21/10/2026, worst first. Each links to what it means and how it is fixed.

• high
  Insufficient color contrast ratio

  Low contrast text is difficult or impossible to read for users with low vision, color blindness, or in bright ambient lighting.

• medium
  Cache-Control header missing

  Proper caching prevents browsers from re-downloading unchanged resources, dramatically improving repeat visit performance.

• medium
  Form inputs missing autocomplete attribute

  WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.

• medium
  Image file too large (>500 KB)

  Images typically account for 50-75% of a page's total weight.

• 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
  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
  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
  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.
