This URL got a zero score for the Accessibility audit section.

Here is the the Lighthouse Report

enter image description here

I wanted to know how find the locations at which this check failed because I cannot find a way to figure it out.

    I have trouble with the red text on the gray terminal background (symbols) and the dark yellow text on the same background (comments). Try a different theme for the syntax highlighting and see if you can find one that has better contrast for everything. Jun 23 at 9:48

The problem seems to be with CSS overflow properties. Seems overflow property can hinder Lighthouse's ability to run Accessibility audit.

Reference: https://github.com/GoogleChrome/lighthouse/issues/11721

I saved your page as HTML on my local machine. When I tried the lighthouse audit for the page, I encountered the same error. I then created a copy of the page with all overflow properties removed from the source. Lighthouse was able to measure Accessibility now.

overflow removed page

Note: The report for the new page also shows the specific elements where you have to improve the contrast ratio.

  • Hi @Kannan - Thanks for the answer. I didn't find any element/css with overflow-x attribute.

  • The page contains overflow properties in inline style. Please check the source. And, sorry, I removed overflow properties and not overflow-x.

  • And one more point: A question mark in accessibility (in your screenshot) denotes an error and not a zero score.

  • You were correct, the code blocks were very which made the experience poor. I've shortened the width of the code lines.
