The body tag says to the browser "get out of 'metadata' mode and start
writing stuff to the screen". Presumably, everything between <body> and
</body> is there for 'presentation' in the browser. In this sense, then,
it's merely a 'mile marker' on the page.
Unfortunately, even as a writer, if you are going to build web pages, you
are going to have to learn some HTML. In the same sense, if I want to be a
writer I am (probably) going to have to learn how to use a word processor.
I could say that I have no interest in computers, but who do you know that
doesn't use one?
As the web becomes more complex, the programs that author pages to work on
the web must also become more complex.
Now - you can use CSS to change the format and style for your 'normal'
paragraph on any page. How would you like to change it?
