HTML is a language that is used to describe documents. The documents are transferred all across the internet as web pages. The web pages are organized by using HTML elements to describe there purpose. (see pic below)
Here is the structure of the HTML documents, by using semantic elements and elements that have specific purposes like headers, paragraphs, lists, and tables of data. Other elements are for displaying an image or creating a hyperlink to navigate to a specific location. There are also elements that allow us to link to external resources like CSS styles or write code in a scripting language like JavaScript. (see pic below)

(I will explain Cascade Style Sheets (CSS), and JavaScript in my future posts but for now lets stick to HTML.)
Think of the page format like a human body. You have your head, body and feet. The same is true for an HTML document. First declare your page an HTML document by typing on the first line of your code <!DOCTYPE HTML> and then open an <html> tag; so you can begin creating your “human”. Type your <head> tag right under your <html> tag and inside that tag put a <title> tag and the text you write in that tag will display inside of the tab in your web browser. (see pic below ex. “The Bay Area’s…”)
Then you create a <body> tag where most of the content will be placed. You put a <header> tag and that’s where you create the title of your page. Then you could use the <h1>tag to create a heading for the page. (The <h1> tag will have a more profound size and as you go down to <h6> the size will decrease.) The <p> tag is the paragraph tag you would put text in that you want the page to display. There are a whole trove of tags that you can utilize to help you get the structure and look you want on your HTML page to have. Never forget to close your tags with a close tag, for example a closing tag to a <body> tag will be </body> for a <h1> tag its </h1> so that convention pretty much goes for all tags except for a few such as an anchor tag which is used as a single tag <a> and also an image tag <img>. With all this you are well on your way to creating a website.
