Learn HTML by Building a Cat Photo App - Step 55

I am not able to do step 55 as there is no clarity. Please help

Can you ask a more specific question about what you don’t understand? Also, it would help to see your HTML 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.
