The test fails but I don't see what's wrong? Help

Tell us what’s happening:

Your code so far

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;
.fullCard {
  width: 245px;
  border: 1px solid #ccc;
  border-radius: 5px;
  margin: 10px 5px;
  padding: 4px;
.cardContent {
  padding: 10px;
.cardText {
  margin-bottom: 30px;
<div class="fullCard">
<div class="cardContent">
  <div class="cardText">
    <p><em>Google was founded by Larry Page and Sergey Brin while they were <u>Ph.D. students</u> at <strong>Stanford University</strong>.</em></p>
  <div class="cardLinks">

Challenge: Adjust the Size of a Header Versus a Paragraph Tag

Link to the challenge:

Could you please explain a bit more about your troubles? What do the failing tests say?

This actually just passed for me, with your code.

For me doesn’t pass. Sorry my poor English.
Let me try another browser. May be it will pass

This continues to tell me to put: “font-size: 27px;” on tag h4 when I run the test, but I dont see what’s wrong with this code.
Sorry my poor English

Your code in your first post works for me too:

Do you have some extension that is modifying your CSS? Is your browser window zoomed?

Is there a check mark ✓ or is it an X?

Your code should add a font-size property to the h4 element set to 27 pixels.

Just an idea: Did you maybe select a zoom factor or font-size in your browser different from 100%? Maybe that helps to pass the test.

Very thanks for the help. I solved the problem changing the browser.
