Headings come in many different sizes. While in HTML an h1 heading is denoted by <h1>, in wikitext, it is denoted by an = sign. For instance if I wanted an h1 heading I would type what is below. However, it is unadvisable to use h1 headings in an article, always use h2 headings such as the ones below.

== h2 ==
