Currently stuck at this step

I tried multiple combinations but nothing seems to work, the following code is clean with no alterations of mine.

   **Your code so far**

Challenge: Step 43

Link to the challenge:

We need to see your alterations so we can see what you have tried. To display your code in here you need to wrap it in triple back ticks. On a line by itself type three back ticks. Then on the first line below the three back ticks paste in your code. Then below your code on a new line type three more back ticks. The back tick on my keyboard is in the upper left just above the Tab key and below the Esc key.

You are being asked to add the class “inline” to the input elements. You have already added classes to elements in the previous courses. Review the HTML for the last step of the Colored Markers course to see how you did it there.
