Overview of the Codecademy Web Development Course

This is a brief overview of the course I am taking on Codecademy. It teaches three different forms of code:

  • HTML
  • CSS
  • Javascript

And it has projects and quizzes after each lesson. Each lesson takes about 10-20 minutes to complete (It varies depending on the lesson.) So far I am about 15% through the course. Currently I am working on Javascript. Here is a picture of what I've completed so far:

HTML is used for the basic editing of a website, it controls the main body where the titles are, etc. 

CSS is used for the look of a website, for example, you could change the color of a banner and assign it to the main banner in the HTML code.

Javascript is used for the back-end of things and can create functions to react differently to different inputs and create different outputs.

All of the three codes work together to create a nice looking and working website.

Work together HTML CSS and Javascript
Here’s an example of a JavaScript code snippet for an age calculator. The code asks for the input of your date of birth and then it calculates how old you are based on that date:

This is an example of CSS code that is for changing the font, color etc. for a specific section of text. You can’t do this formatting In JavaScript or in HTML:

This example is of a sample of code from html that displays an image from an image link and controls the display size. This is also not possible to do in JavaScript or CSS:
