Use CSS Selectors to Style Elements

Problem Explanation

CSS selectors are widely used to apply styling to all instances of a particular element.

To apply the color purple to all the h2s on the page, you can define the following CSS inside a <style></style> block.

h2 {
  color: purple;
}

This will apply the color purple to all <h2> headings. If you are using the style="color: purple" attribute on each <h2> element, you can remove it and instead define it in a single place inside a <style></style> block.

Solution (Click to show/hide) 
<style>
  h2 {
    color: blue;
  }
</style>
<h2>CatPhotoApp</h2>
<main>
  <p>Click here to view more <a href="#">cat photos</a>.</p>

  <a href="#"><img src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back."></a>

  <div>
    <p>Things cats love:</p>
    <ul>
      <li>cat nip</li>
      <li>laser pointers</li>
      <li>lasagna</li>
    </ul>
    <p>Top 3 things cats hate:</p>
    <ol>
      <li>flea treatment</li>
      <li>thunder</li>
      <li>other cats</li>
    </ol>
  </div>

  <form action="https://freecatphotoapp.com/submit-cat-photo">
    <label><input type="radio" name="indoor-outdoor" checked> Indoor</label>
    <label><input type="radio" name="indoor-outdoor"> Outdoor</label><br>
    <label><input type="checkbox" name="personality" checked> Loving</label>
    <label><input type="checkbox" name="personality"> Lazy</label>
    <label><input type="checkbox" name="personality"> Energetic</label><br>
    <input type="text" placeholder="cat photo URL" required>
    <button type="submit">Submit</button>
  </form>

Here’s the solution guys:
< style>
h2 {color: blue;}
< /style>

< h2>CatPhotoApp< /h2>

< p>Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching attack your ankles chase the red dot, hairball run catnip eat the grass sniff.< /p>

I had to make spaces inside tags to could show you the code itself, just remove the space and should be good.

Hey XanderHall,

I see from your code in lines 2 + 3 that it looks a little jumbled, I had a similar issue in the placement of the CSS element. I would reset the code and keep CSS style element at the top and away from the actual (h2>CatPhotoApp</h2) as the CSS element will point to this when you declare it, so it should look a little like the code above and you’ll be rockin’!

Keep on keepin’ on :slight_smile:

I have completed this challenge with the same solution that many other users have come to submit.

The one issue that I ran into that may help others here is that the challenge sometimes does not recognize a correct solution when pasting in from an external text editor. I ran into this as I like to edit with an external text editor because it will auto-complete the tags. However, when pasting into the browser and submitting it is incorrect. I instead had to type the solution manually in the browser and submit, then it accepted as correct.

Hope this helps,

-Crypt.

you have deleted your actual h2 element meaning youve made nothing blue.

Spacing seems to be an issue here, which seems off putting. Nonetheless it accepted my answer. :laughing:
