Test might have error for Applied Visual Design: Set the font-size for Multiple Heading Elements

Tell us what’s happening:
when I tried “Applied Visual Design: Set the font-size for Multiple Heading Elements” in Responsive Web Design Certification, the test always shows the definition for H6 font-size is wrong, but actually it’s same as other Headings. I guess the test maybe wrong this time. would you please check it?

Your code so far

h1 {
    font-size: 68px;
h2 {
    font-size: 52px;
h3 {
    font-size: 40px;
h4 {
    font-size: 32px;
h5 {
    font-size: 21px;
h6 {
    font-size: 14px;
<h1>This is h1 text</h1>
<h2>This is h2 text</h2>
<h3>This is h3 text</h3>
<h4>This is h4 text</h4>
<h5>This is h5 text</h5>
<h6>This is h6 text</h6>

Your code looks correct and passes on my end. It could be a browser issue, do you have any ad-block or plugins enabled or anything? Those always seems to be the culprit for these kind of issues, if not perhaps try in a different browser such as Chrome or Firefox and see if it gives you the same results.
