So, to take advantage of this update, replace the code you entered from Step 7 with the new code, and set the inCommMaxComments variable to the maximum number of comments you want to see beneath each post, then replace the code you pasted from Step 12 with the new code, and finally, delete the max-height styling rule from the inComm class you entered in Step 17, like this:
.inComm {
overflow: auto;
padding: 0 10px;
}
overflow: auto;
padding: 0 10px;
}
