HEADERS
Headers in html are a natural way of adding titles to text. They begin with <h1>, the largest, and go down to <h6>, the smallest. Each is then closed with <h1> through </h6>, respectively. They are also block text, creating space before and after. By default, headers will always be in bold text.In general, <h1> should only be used once, on the largest heading of the page. It should contain the most important keywords relating to your website (and probably reflecting the title) as it is often used by search engines in sorting results by relevancy. Below are the headers, largest to smallest.
