What Dr Urls found on leancode.co
From the audit of their public home page on 10/11/2026, worst first. Each links to what it means and how it is fixed.
- highMissing landmark elements
WCAG 1.3.1 requires that page structure is programmatically determinable.
- mediumDuplicate ID attributes found
Duplicate IDs cause label elements, aria-labelledby, aria-describedby, and fragment link targets to associate with the wrong element.
- mediumExcessive DOM size
A large DOM tree directly impacts Interaction to Next Paint (INP), a Core Web Vital.
- mediumForm inputs missing autocomplete attribute
WCAG 1.3.5 requires input purpose to be programmatically determined for inputs collecting user information.
- mediumImage file too large (>500 KB)
Images typically account for 50-75% of a page's total weight.
- mediumImages missing width and height attributes
Missing image dimensions are the leading cause of Cumulative Layout Shift (CLS), a Core Web Vital and ranking factor.
- mediumMissing skip-to-content navigation link
WCAG 2.4.1 requires a way to bypass blocks repeated on every page.
- mediumRender-blocking CSS or JavaScript
Render-blocking resources directly impact First Contentful Paint (FCP) and Largest Contentful Paint (LCP), both Core Web Vitals metrics.
- mediumToo many external CSS stylesheets
Multiple CSS files multiply HTTP requests and increase the total blocking time before the page can render.
- lowCSS files are not minified
Unminified CSS files are larger than necessary, increasing download time and delaying rendering.
- lowDuplicate heading text on same page
Duplicate headings reduce the uniqueness and semantic clarity of the page structure.
- lowExcessive inline CSS
Inline CSS cannot be cached separately by the browser, so it is re-downloaded with every page load.
And 5 more. 6 security findings are not listed on this public page; the site's owner sees them in a full audit after claiming it.
