As mentioned, HTML stands for HyperText Markup Language which is considered the language of the web. A HTML document is a plain text file that is read by a the browser. An HTML document is made up of a few different sections. In newer versions of HTML we start by including a document type and then a series of other HTML tags that give the browser instructions on how to display. A tag is comprised of a left and right angle bracket or a greater than and less than symbol with the name of the tag inside of the brackets. Most tags come in pairs and are used to surround other markup. An example is the tag which you see at the start and then again at the end of a document. You may have noticed that the closing tag includes a backslash to indicate that the tag pair is closing. In instances where a tag does not have a closing pair (such as an image or meta tag, you can put the trailing slash at the end of the tag). So the HTML tag wraps both the Head and Body tags. The head tag gives instructions for behind the scenes and the body tag wraps what we see in the browser window.
