“Below your .small-text element, create a new p element…”
This means that the new p element should be placed below, or after the .small-text element. You have placed it before the .left-container element.
“…below the .left-container element, create a new span element with the text 230.”
This means is should be below, or after the entire .left-container element, which includes both the opening and closing div tags for that element. You have placed it inside the .left-container element.
You’ll need to paste your updated HTML in here so we can see what you’ve 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 may also be able to use Ctrl+e to automatically give you the triple back ticks while you are typing in the this editor and the cursor is on a line by itself. Alternatively, with the cursor on a line by itself, you can use the </> button above the editor to add the triple back ticks.
Also, remember, when you put a new element after another element, such as a div, that means after both the opening and closing tag for the div.
The 230 span goes below the .left-container div. You have put it inside of the .left-container div. As I mentioned previously, when you put a new element after another element, such as a div, that means after both the opening and closing tag for the div.
