Let's add some custom font and style some of the missed HTML elements. We have used Robot font, you can use any font of your desire.
It's a simple one-liner code to mention the font in the app. Add the following line to your index.html page just after the <body> tag:
<link href="https://fonts.googleapis.com/css? family=Roboto+Condensed" rel="stylesheet">
And in main.css apply the font to an entire HTML page:
html * { font-family: 'Roboto Condensed', sans-serif; }
Reload the page. Looks beautiful now, doesn't it?
