title: HTML tag to prevent HTML tags to be executed?
body: <p>Basic question which I thought of asking on Superuser, but it is a programming question I think.  I just started learning HTML, so please bear with me.</p>
  
  <p>How can I prevent a program from interpreting an HTML tag / syntax?  <strong>For example</strong>, I want to write a flash card like this:</p>
  
  <blockquote>
    <p>The html code for <code>&lt;</code> is <code>&amp;lt;</code></p>
  </blockquote>
  
  <p>I would like a solution that would work for any or most syntax, not just for <code>&lt;</code>.</p>
  
  <p>How can I enter the syntax (without any space) to make sure the code isn't interpreted?</p>
