CSS CSS Basics (2014) Understanding Values and Units Styling the Intro Paragraph

Getting frustrated over one issue.

ok, I got into CSS and classes.

I have watched the videos where after making a class. You can create class defined rules.

"In the style sheet, select the intro class and add a font-size property. Using 16px as the parent font-size context, give intro an em font-size value equivalent to 20px."

In this issue. I am trying to show that p.intro{ font-size: 1.25em; }

in or around the "p" element. What am I doing wrong to keep getting this wrong?

index.html
<!DOCTYPE html>
<html>
  <head>
    <title>Lake Tahoe</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
  </head>
  <body> 
    <header id="top" class="main-header">
      <span class="title">Journey Through the Sierra Nevada Mountains</span>
      <h1>Lake Tahoe, California</h1>
    </header>
    <div class="primary-content t-border">
      <p class="intro">
         /* Class */
          .intro
          {
            font-size = 1.25em;
          }
        Lake Tahoe is one of the most <span>breathtaking attractions</span> located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.
      </p>
      <a href="#more">Find out more</a>
    </div>
    <footer class="main-footer">
      <p>All rights reserved to the state of <a href="#">California</a>.</p>
      <a href="#top">Back to top &raquo;</a>
    </footer>
  </body>
</html>
style.css

You're defining the CSS inside the <p> element and you can't do that!

You can do it inline

<p class="intro" style="font-size:1.25em;"></p>

Inside the head element

<style>
   .intro {
      font-size: 1.25em;
   }
</style>

Or in an external css file

.intro {
   font-size: 1.25em;
}

it doesn't work...

What's with all of the = signs is it not :

how do you find the equivalency out? Parent size is 16px, and they want 20px equivalent. Does that mean 20/16?

Yes, you will divide 20/16 which equals 1.25em

You have to write the rules into the CSS file: where it says /* Complete the challenge by writing CSS below */ don't write into the HTML file directly.

haha, it took me several tries to get this, I just had to change the (=) sign to a colon (:)
