Boston College Create a CSS Code Computer Coding Task

So this is the original code. I added <div> tag from line 38 but I’m not sure if Im supposed to do that. Can you pls take a look at the instruction. Thanks Step 2. The CSS text-align property is used for aligning the inner content of a block element.   To align content center, use  text-align: center;    To center align a block element itself, use margin: auto; which evenly set the right and left margin of the element.  To do:  Uncomment line 6 in center-ex1.html.  Check if all the “Lorem Ipsum” text on this page is centered.  Can you explain why some texts are not centered?  Fix this problem and center all text by adding a single CSS rule in the CSS class selector textdiv. Step 3.  To center align an <img> element, which is an inline element, you can use different approaches. Approach 1:   Use  text-align: center; to center the image within its parent container. Approach 2:   Turn the <img> into a block element by changing its display property from the default inline value to a block using display: block;  and then use  margin: auto; so the image is centered within its parent container. To do: Add a single rule in the CSS class selector .imgdiv to center the “number two” image on the page.
