====== HTML and CSS additionnal recommendations ======

With the aim of being pragmatic and quickly operational, a few accessibility recommendations of the WCAG have not been kept in the core of this document. These criteria are rarely applicable in a web project or are of low priority. Nevertheless, they are listed below and will be described in the Accede Web project wiki.
