## HTML Best Practices to start out with

- Use start and end tags, even if optional
- Lower case element and attribute names
- Use quotes around attribute values

These best practices essentially follow the "XML" syntax rules for HTML5

### XML Syntax
    <!DOCTYPE html>
      <html lang="en">
      <head>
          <title>My Document</title>
          <meta charset="utf-8" />
      </head>
      <body>
          <h1>My Document</h1>
          <ul>
              <li>coffee</li>
              <li>tea</li>
          </ul>
          <img src="images/mug.jpg" alt="mug" />
      </body>
      </html>
| ### SGML/HTML Syntax
    <!DOCTYPE html>
      <HEAD>
          <TITLE>My Document</TITLE>
          <META CHARSET=utf-8 >
      <BODY>
          <H1>My Document</H1>
          <UL>
              <LI>coffee
              <LI>tea
          </UL>
          <IMG SRC=images/mug.jpg ALT=Mug >
