Basic Structure of an HTML5 Document
<!doctype html> HTML5 DOCTYPE declaration <html> </html> document tree <head> </head> head element title element <title>New Movie</title> <body> </body> body element The basic structure of an HTML document starts off with a document declaration. The document declaration lets the browser know what type of documents is being sent to the browser. The type of document depends on the version of HTML used to create the HTML markup. Browsers, depending on their version are able to interpret what the different HTML document versions can be. Some older browsers might not be able interpret the newer version of HTML markup codes. An older browser cannot interpret the newer HTML5 elements. As a result, additional code must be used to enable older browsers to interpret the newer HTML codes. [Transition 1] – The first tag to be placed in the document is the document type declaration. This defines and alerts the browser of the version of HTML document. In this example the html doctype indicates a HTML5 document type. [Transition 2] – The next tags to be declared in the document is the HTML opening and closing tags. These tags identify the document tree. In this case it identifies a HTML document tree. [Transition 2] – The next tags to be declared are the head tags. These tags identify the head section of the HTML document. The head tags include information that will not be displayed on the web page. This include the page title, css codes anjavescript codes and any other additional information you do not want to be displayed when the web page is rendered by the browser.

Coding Recommendations for HTML5
Use lowercase HTML attribute consists name, an equals sign (=), and value. Attribute values don’t have to be enclosed in quotes if they don’t contain spaces. Attribute values must be enclosed in single ‘ ’ or double quotes “ ” if they contain one or more spaces, but you can’t mix the type of quotation mark used for a single value. Boolean attributes can be coded as just the attribute name. Code multiple attributes, separate each attribute with a space. For consistency, enclose all attribute values in double quotes. Use whitespace to indent lines of code Overuse of whitespace increases file size. 4/6/2019 Copyright © Carl M. Burnett

Common HTML Coding Errors
An opening tag without a closing tag. Misspelled tag or attribute names. Quotation marks that aren’t paired. Incorrect file references in link, img, or <a> elements. 4/6/2019 Copyright © Carl M. Burnett
