For the third lesson in an on-going series, I will be covering a few HTML tags specifically relating to formatted text. These tags will help with search engine indexing, special browsers for blind, and for stylesheets (covered in future lessons). None of these tags self-close, meaning they need a matching closing tag at the end.
The first set of tags are called the "heading" tags. They are <h1>, <h2>, <h3>, <h4>, <h5>, and <h6>. These tags are meant for heading across the tops of pages or for section breaks inside pages. In general practice, I rarely see more than just <h1> and <h2> used. Browsers will generally display <h1> as the biggest text with each other heading tag slightly smaller. A heading to a page may look like this:
<h1>My Homepage</h1>
The <span> tag is used for snippets of text that may be visually separated from nearby text. I will not go into detail of this one now but will revisit is when covering stylesheets.
Two very common tags for splitting out blocks of text are "paragraph" <p> and "division" <div>. The <p> tag will generally have a margin of a few line feeds after closing, and <div> will default to 100% page width with no margin. (Stylesheets can change those.) Search engines may pick out text from these tags for indexing as general page content. Also, browsers for the blind will read out-loud from these tags after the heading tags. Thus, it is good practice to always place page body text inside one of these tags.
