Responsive social link profile using angular and flex

Looks nice. I have couple of feedback.

• The <header> or the banner role is usually used to wrap content that is common across multiple pages of a website. Usually you see it at the top of the webpage wrapping the site logo and a navbar. I would not use a <header> in this challenge.
• What you need is a <main> landmark element. Every web page needs a <main> element wrapping the main content of the page.
• The <nav> element is for a list of links that navigate within the site. Not for links that navigate to outside websites such as social media sites. In this case having the links inside a <ul> is enough.
