h1 element not visible in workspace preview

I launched a new workspace and made some adjustments along with Mr. Hernandez and saw in the preview that the h1 element is not visible.

The color is set to white in the CSS and the text is there in the index.html file. 

<h1>Lake Tahoe, California</h1>

h1 {  
  font-size: 90px;
  color: white;
}

Interesting...

I left the program for a few days and have come back to find the problem solved. I made no changes to the code at all. hmmm

Hi Jesse,

By default browsers have a background colour of white thus you won't see your text if it's the same colour, try changing it to red for instance and you should see it appear.

h1 {  
  font-size: 90px;
  color: red;
}

Thanks,

I tested it in several colors. The header is set to background-color: orange; and the h1 element is in the header. So the white text should show up on the orange background.

h1 { font-size: 5.625em; color: white; }

.main-header { background-color: orange; }

So it isn't visible in any text color. It just isn't there. I checked the html for problems and couuldn't find any. This has only happened on the latest workspace for this course.

<body> 
    <header id="top" class="main-header">
      <span class="title">Journey through the Sierra Nevada Mountains</span>
      <h1>Lake Tahoe, California</h1>
    </header>

.main-header {
  background-color: orange;
}

h1 {  
  font-size: 5.625em; /* 90px / 16px */
  color: red;
}

In the HTML file, give the h1 element the class main-heading.

You need to assign the h1 element with the class "main-heading"

<h1 class="main-heading">
