To italicize something, it's simple.
Copy and paste what you want to quote.
Put your cursor at the beginning of each section on which you want to comment. Type this symbol:
<
Then type the letter "i" by itself
Then type this symbol:
>
That will create the HTML code for "open italics."
Put your cursor at the end of the section on which you want to comment. Type this symbol:
<
Type a backwards slash:
/
type the letter "i" again
Then type this symbol:
>
That is HTML for "close italics."
Hope this helps
