After having developed a first version of the site in static HTML, I made the decision to integrate dynamism into it thanks to PHP and MySQL. This decision was motivated by the acquisition of a hosting provider that allowed dynamism.
Even though I wasn't bragging about it anymore, I still used tables to format the site. It is however interesting to note that I was already trying to respect certain standards, since the site is - despite the use of tables - valid HTML 4.01.
