The two columns never show on the preview

I checked my code twice, I can't see what I am doing wrong. Is it possible that it's because I use the normalize.css 5.0.0?

Here are my codes

That's OK, I solved the problem myself ;) We can see there is something wrong here thanks to the styling:

.profile-photo {
        float: left;
        margin: 0 5% 80px 0;
    }

I could have been blocked on this all day long... Anthony
