This was a change from an old project where I made a static website which can be
found here AnimalRehomingStatic.
In this version I made a dynamic version of the site using PHP and MySQL.
I used a basic MVC style architecture, although there are no specific controllers.
All the controller logic is in index.php
which also deals with routing.
One of the issues I wanted to address from the original AnimalRehomingStatic was the size of the single CSS file I used.
To address this problem I choose to use SASS.
