  <title>The Idea of Hypertext</title>

   <h1 style="text-align: center; font-family: sans-serif">Hypertext</h1>
    <b>HTML</b> stands for HyperText Markup Language.  Hypertext 
    expresses the idea
    that you can click on what you are reading to jump to something else
    which is related.  This is the same 
    <span style="font-style: italic">hyper</span> in hyperspace 
    that the characters in your favorite
    science-fiction story are always jumping through.  The idea is to
    go immediately to a distant place.  In the case of documents,
    you are going to
    a place which may be far away in whatever scheme is normally used
    to order the documents.
    HTML is a way of expressing hypertext, but the idea
    is older.  The
    first mention is probably
    Vannevar Bush's description of Memex
    in 1945.  The term was coined by Ted Nelson in 1965, and was
    popularly embodied in the HyperCard application shipped with the
    original Apple Macintosh (from

   <div style="margin: 1cm; border: 1pt solid blue; padding: 10pt;">
     The <span style="font-family: monospace;">span</span> tag is just
     a holder for its style attribute; the tag itself changes nothing.
     The <span style="font-family: monospace;">div</span> tag is similar,
     except it also makes its contained text into a separate block.
