Task 4 of 4 CSS

I am writing the correct code and have inserted it in many places. What am I doing wrong?

style.css 
/* Complete the challenge by writing CSS below */

.progbar a::after {
  content: attr (href);
  display: block;
  width: 50%;
  height: 100%;
  border-radius: inherit;
    background-color: #5ece7f; 
}

.progbar::before {
  content:"";
    display: block;
    width: 24px;
    height: 24px;
    border-radius: 50%;
    position: absolute;
    left: 49%;
    top: -9px;
    background-color: #7dd898; 
}

.progbar {
  height: 6px;
  border-radius: 3px;
  background: #d6d7d9;
  position: relative;
  margin-bottom: 3.875em; 
}

The answer is without a space. I believe something may be wrong with the grader. When I wrote .progbara::after{ content: attr(href);

instead of

.progbar a::after{ content: attr (href);

I even watched the video, there is a space between the class and a. Why did the grader tell me I am wrong. :( ??

task 4: Finally, create a new rule that will insert a pseudo-element after an a element. As the content value, define a CSS function that will insert an href attribute's value as content.

You need to create a new rule for an "a" tag, it dosent say create a new rule for an "a" tag inside a .progbar class. Hope this helps.

Hi Alycia,

As Victor mentioned, you need to create a brand new rule that targets only "a" tags. Right now you are only modifying "a" tags that are inside the .progbar, and there aren't any "a" tags there!

I had done that. I believe there was a glitch. I did not put a space between .progbar and a and then it worked. Thank you all for your help.
