CSS Build a Responsive Navigation with Flexbox

My logo isn't popping up once I put the display: flex for the .main-header, .nav tag.

Once I put the display: flex; for the .main-header, .nav tag it disappears. Everything that I typed in is correct. I check multiple times. I don't understand what the issue is. If anyone has a solution that can help out my code, let me know, where I went wrong. Please and thank you. Main Styles --------------------------- */ .main-header, .nav { display: flex; }

.main-header { padding-top: 2em; }

.site.logo { width: 110px; }

.nav { margin-top: 1.5em; }

.nav a { display: block; color: #797e83; font-size: 1.125em; font-weight: 300; text-align: center; padding: 0.4em; border-bottom: 1px solid #ebecec; }

.nav a:hover { color: #0b0b0b; border-bottom-color: #52bab3; }

The problem is your site logo class definition. You have it as .site.logo, but it should be .site-logo (with a hyphen between, rather than a period). Correct that and you should once again see the logo.
