Exercise 1a: Use a real browser, spot things in HTML

Open up Chrome (or any other browser)
Go to https://en.wikipedia.org in that browser
Look for:
- Some text which is bold (remember what it says)
- Some text which is italic (remember what it says)
- Some text which is a hyperlink (remember what it says)
Choose the "view source" option (or "inspect element")
Find the text you found

Here's what's happening:

graph LR;
    browser(Browser on your computer)
    server(Wikipedia web server)
    browser-- request for a particular page --> server;
    server -- response containing HTML -->browser;

Questions:

What's the HTML tag meaning 'bold'?
What's the HTML tag meaning 'italic'?
What's the HTML tag meaning hyperlink? What happens when you click the link? The browser goes to another web page - how does it know where to go?

(you'll need to know these things later!)
