You don't make HTML, you write it.
To have a piece of text in html, you merely type it into the HTML file, it isn't even necessary to insert tags for such a basic task, I'm assuming you have placed in the basic tags thus far (Body, html, etc.). If you wish to format the text, then you will need to add tags, opening and closing either side of the text, you can find these and much more information about HTML on the links below.
