You have to tell us which course and step this is for. A link to the exact step would be best. In the future, use the Ask for Help button in the step to submit your post as it will automatically include all of this information.
Also, we need to see your actual HTML here. 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.
