CSS FLEXBOX, JS

Hello! Great work, so is the responsiveness. The JS code looks neat too. ~

I have a few suggestions:

1. Since you're attaching the background-image to .images, you can try making .images stick to the bottom of the screen by using:

position:absolute;
bottom:0;
left:0;
right:0;
margin:auto;

1. Wrap the main content of the site in main tag.

2. Wrap each social media icon in a tag.

Noted. I was just focused on the countdown, I got tired of the UI. I would make changes right away
