Thank you so much for the solution to the accordion issue, hyperlinks now work perfectly.
Thank you as well for the CSS code to customize accordions, that will be useful and this is very kind of you.
About portfolio description, I invite you to go here. Is there a way to customize the description (the text written in french that begins with a quotation mark)? Mainly font size, color and horizontal alignment, but without any impact on the rest of the site.
