Every morning, a gazelle wakes up. It knows it must run faster than the fastest lion or it will be killed. Every morning, a lion wakes up. It knows it must outrun the slowest gazelle or it will starve to death. It doesn’t matter whether you’re a lion or gazelle. When the sun comes up, you’d better be running.

Ladies and Gents, the DOM.

Let’s take a closer look at the DOM.


Document Object Model


  1. DOM is the DNA of a web page. Changes made to it are reflected in the browser just as changes to a person’s DNA is reflected tangibly in the person.
  2. Browsers use HTML to create DOM which is used to display structured and styled content.
  3. Available inside Chrome through two variables:
    • window + document
    • window is where everything is...we see nothing w/o it
      • it is important not to alter this too much because it is the container that houses operating system information
    • document is the object we will use to interact with the DOM

DOM Nodes

Represent all components that make up a web page

Inner Node / Child Node

Nested string or something similar

Outer Node / Parent Node

Has a start/end tags
    • Example:
<p>I am a paragraph.</p>

Self-Closing Elements

Only have a start tag    
    • Example:
<img src="https://media.giphy.com/media/3o6MbkZSYy4mI3gLYc/giphy.gif" alt="A policeman"(/ <- this is optional here)>

DOM programming is using Javascript to find/select, remove/insert, or adjust HTML elements.
