In this lesson ( [CSS Documentation and Debugging]) it ask you this :

In the “Values” section, find a value that will turn off the display of an element. Add a display property with that value to the h1 rule in the @media query at the bottom of style.css .

but nowhere does it say what to set the max width at, after i clicked the get help button it sets the media query as a max width off 800 px, why did it choose 800 px specifically? in our former lessons where they gave us the reference guide on when a screen breaks for tablets and cell phones and other screens, 800 was not a number any of them fell on, so why was 800px chosen?

why are there two css links at the header of the html?

Hi, I am on this course, and I think I found a bug.

Not only that, I think ALL the lesson have this bug.

Here is my problem:
I typed the same code as the code that codecademy gave me after I clicked Get Code Solution, but before I clicked Get Code Solution, codecademy gave me a NO.

Ther is NO diferrence between my code and the solution code. Here is the whole code I typed:

nav {
  padding: 25px;
  font-family: 'Roboto', sans-serif;
  background-color: #F25F5C;

h1 {
  float: left;
  margin-top: 5px;
  color: white;
  font-size: 36px;

ul {
  float: right;

li {
  display: inline-block;
  margin-right: 25px;
  text-align: center;
  background-color: #28587B;  

a {
  display: inline-block;
  width: 150px;
  padding: 10px 0;
  text-decoration: none;
  font-size: 24px;
  color: white;

.clearfix:after {
   content: " ";
   visibility: hidden;
   display: block;
   height: 0;
   clear: both;

@media only screen and (max-width: 800px) {
  h1 {
    display: none;
  li {
    margin-right: 10px;

  a {
    width: 100px;
    padding: 5px 0;
    font-size: 16px;

So what is wrong here?

  • There is an minor error I didn’t notice in my code.
  • Codecademy has a bug.
  • I have other problems. (If you choose this one, please write the exact problem in the reply.)

There are actually 3

<link href="https://fonts.googleapis.com/css?family=Roboto" rel="stylesheet">
<link rel="stylesheet" type="text/css" href="reset.css">
<link rel="stylesheet" type="text/css" href="style.css">
  • The first one is used to import the Roboto font from google fonts
  • The second one is used to apply the styles in reset.css to the HTML document
  • The third one is used to apply the styles in the style.css to the HTML document

reset.css is responsible for resetting all the browser’s default styles (such as margins and paddings) while style.css is used to add styles to our document
