Ignoring the ‘header’ information at the top of the code, the message as you see it is stored within the body tag, this begins with <body> and is closed with </body>.
Formatting is added to the message using additional tags, for example Paragraphs are defined with a paragraph tag, this begins with <p> and ends with </p>, should we wish something to be in bold we would ‘wrap it’ in another tag, a bold tag, <b>bold text</b>.
To expand upon this basic understanding, there is a very good beginner’s guide to HTML on the w3 website with some helpful interactive examples. To view it click here.
