Like most of the WAI Website, the Quick Reference is a Jekyll project, with a Gulp component that creates JS & CSS. Follow the Jekyll Installation Instructions to install Jekyll. Unless you need to edit CSS or JS, you can ignore Gulp.

The data is saved as wcag21.json in the _data directory. Due to the complexity of the WCAG standard, the JSON file format is also quite complex. The data is exported from the WCAG source code and handed over to this repository.

Note: In the past SC text or techniques have been missing from the export. Unfortunately due to the complex nature and different formatting of the export, it was impossible to spot potential gaps in the new files. Usually the public is quick to inform us about missing data.

After checking out/updating this repository and installing Jekyll dependencies, use the following command to generate a new version of “How to Meet WCAG (Quick Reference)”:

bundle exec jekyll build --config "_config.yml,_config_prod.yml" --profile

This RewriteRule "^([cij].+)" "20191004/$1"command generates a _site folder with the generated page and associated JS/CSS files and graphics. On a fast computer, this takes a few seconds.

Rename the _site folder to the current date in the format YYYYMMDD, for example 20210110 for January 10, 2021. Then move the folder to the W3C CVS inside the folder /WWW/WAI/WCAG21/quickref/. Edit the .htaccess in the same folder and replace the previous date in the following two lines with the new date:

RewriteRule "^$" "YYYYMMDD/index.html"

and

RewriteRule "^([cij].+)" "YYYYMMDD/$1"

After adding the directory and changing the .htaccess file, commit all files and the new version of the quick reference is online.
