The cours tries to prepare you on how HTML-Documents are properly written.

It all start’s with you, using a Browser in which you load a HTML-file, which we will call the HTML-Document.

This document has a minimal build of

<!DOCTYPE html>
  <html>
     <head>
          <title> </title>
     </head>
     <body>
     </body>
  </html>

The Browser =load’s= this document into Memory in a pattern that is described as the Document Object Model in short the DOM. ( the interpretation of the DOM is Browser & Version specific )

            html
             |
       +-----+------+
       |            |
     head          body
       |
     title

In the description of your document in DOM-talk… you will encounter terms like: parent children sibling descendants ascendants…

The HTML-Element has no parent but is a parent to 2 child-Element’s the ‘head’-Element and the ‘body’-Element.

The ‘head’- and ‘body’-Element, both being children to the ‘html’-Element are siblings to each-other.

The ‘head’-Element is parent to the ‘title’-Element… the ‘title’-Element is a child of the ‘head’-Element the ‘title’-Element is also a descendant of the ‘html’-Element.

The DOM has several interface‘s over which you can access the data**/**information held by the DOM.

One of the interface‘s is the Element-interface you can divide the interface into properties ( consisting of a property-key and it’s associated VALUE ) and methods ( giving you the functionality to manipulate the Elements ) https://developer.mozilla.org/en-US/docs/Web/API/Element https://developer.mozilla.org/en-US/Learn/HTML/HTML_tags
