To make the heading look like the rest of the posts headings, put h2 in brackets [  ] before the heading, and /h2 in brackets [  ] after the heading. If you want to centre it, use centre and /centre. Just make sure that whatever you write before the heading, you mirror it after the heading.

So in this case, you would write centre h2 basil and viola /h2 /centre. Each code gets its own set of brackets as well. Make sure to use the square brackets or it won't work. :)
