For test #5 you have to change the caption element type to <figcaption>, what you have now is not a valid element (<caption>).
For test #Layout #1, you have to use the correct selector. Your img element has the id of image but your selector is #img. You also have a syntax error on the margin, the values should not be separated by commas.
@camperextraordinaire@lasjorg Yes I am actually using Codepen, I have taken your advice, but unfortunately, the same errors occur in Codepen as mentioned above. I have used JS Bin now and have passed the test in Chrome. I have added the <figcaption> and corrected the margin syntax error now (thanks lasjorg) Thank you both for your helpful advice.
