responsive, mobile first challenge

It was a bit long but i didn't have particular problems on this project, except for two things, and i'll be glad to everybody who will find a solution!!

---

First, i still have a little scroll on the desktop version, but not on the mobile.. i set as always: width: 100vw; height: 100vh; margin: 0; padding: 0; on the body, but i still have it..

---

Second, at the end of the page, in the footer, i set a grid for the links, but i wasn't able to align the text on the left as shown in the reference picture of the project; i tried with the main command, text-align, align-item, align-content and justify-content, but nothing works..

By the way, i will be glad for every comment on every mistakes i made in this projec! Thank you guys and Happy Coding!!
