The challenge tells you if your solution is correct (or not) when you use the "Check Work" button. This code should return a response of "Bummer: Make sure you're setting the font-size of .heading using a rem unit."

But besides the first task not being completed, it looks like some of the originally provided code was removed, plus some code was added that is not part of this challenge. When doing the challenges, be sure to do only what the instructions ask for!

What do you mean? This is what i did. .heading { font-size: 1.8em; }

.title { font-size: 1.625rem; }

h1 { font-size: 5.625rem; } I do not know how to answer the question. Please help me. Thanks

The challenge gives you code to start with that has rules for "html", "header", and ".heading". The first two seem to be missing in the code shown above. Also, the challenge doesn't ask for new rules for ".title" or ".h1".

Is it possible that the code shown here is for a different challenge than the one linked to the button?

What specifically did the instructions ask you for?

Steven Parker I have no idea what you are mentioning about.

When the challenge starts, the provided contents of the first file are this:

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

html {
  font-size: 16px;
}

header {
  font-size: 1.5em;
}

.heading {
  font-size: 5em;
}

Even if you've done the first task, there should only be one small difference on just one line. But compare this to the code you included above and you'll see they are very different!

Steven Parker This is the prompt. The em-based font-size value for .heading is relative to its parent header's font-size value. This causes a compounding issue that makes the font-size value larger than the desired value.

Replace the em units of .heading with a unit that is relative to the root element of the page.

That sounds like the same challenge, and the instructions are only asking for a unit change in just one of the 3 rules. But 2 of the rules shown in the code above have completely different targets and contents compared to what the challenge starts with! It looks like code from a different challenge entirely.

Try starting over and making only that one change in task 1.
