HyperText Markup Language V.5 (HTML5)
HTML5 is the latest evolution of the standard that defines HTML. The term represents two different concepts:

Some rules for HTML5 were established:

Notes:
• Place the opening bracket on the same line as the selector.
• Use one space before the opening bracket.
• Use 2 spaces of indentation.
• Use colon plus one space between each property and its value.
• Use space after each comma or semicolon.
• Use semicolon after each property-value pair, including the last.
• Only use quotes around values if the value contains spaces.
• Place the closing bracket on a new line, without leading spaces.
• Avoid lines over 80 characters.
