I don't know what is wrong with this lesson!

Tell us what’s happening:
I am sure I have all correct to “Decrease the Opacity of an Element lesson”. Even I’ve watched the video lesson and the solution matches with mine.

This is the instruction:
Your code should set the “opacity” property to 0.7 on the anchor tags by selecting the class of “links” .

Your code so far


<style>
h4 {
  text-align: center;
  background-color: rgba(45, 45, 45, 0.1);
  padding: 10px;
  font-size: 27px;
}
p {
  text-align: justify;
}
.links {
  text-align: left;
  color: black;
  opacity: 0.7;
}
#thumbnail {
  box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);
}
.fullCard {
  width: 245px;
  border: 1px solid #ccc;
  border-radius: 5px;
  margin: 10px 5px;
  padding: 4px;
}
.cardContent {
  padding: 10px;
}
.cardText {
  margin-bottom: 30px;
}
</style>
<div class="fullCard" id="thumbnail">
<div class="cardContent">
  <div class="cardText">
    <h4>Alphabet</h4>
    <hr>

  <div class="cardLinks">

Thank you so much for your share RandellDawson! I’m using Safari, I will try a different browser.

This does work in Firefox. As I just tested this. Opacity works in all major browsers It’s strange that you had this issue.

I will try another browser, thanks for your share “six03”

Thanks RandellDawson! I tried a different browser and I passed that lesson.
