We need to see your actual HTML in order to help you. 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.
But from what I can tell, you added elements to the HTML that you shouldn’t have. The example HTML in the instructions is just that, an example, not meant to be used in the solution.
Restart the step to get back the original HTML and formatting since formatting is very important for this step. Then, the only thing you should do is use your space bar to add two more spaces before the opening tag of each of the three child elements in main.
I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
