Used Bootstrap throughout with some css

Good job LakryM. I noticed the mobile page was moved a bit to the right of the screen. The Bootstrap container-fluid class can help with that. Maybe you may have used different utility classes for the different sections. Using bootstrap to get the off canvas side navigation with a drop-down was a little tricky for me as well. Maybe you can look up the navbar section of bootstrap docs, there is an offcanvas solution there. Well done!
