The HTML of the right block should match the XSL version
HTML version : https://code.ametys.org/pages/MAQ/ametys-intranet/master/browse/actu.html
XSL version : https://demo.ametys.org/nightly-intranet-cms/preview/intranet/fr/mon-organisation/l-institution.html
The enclosing div is not correct
The title on the HTML version should be :
<h2 class="ametys-content-title">Besoin d'aide ?</h2>
