Appending to section goes outside the section

April 27, 2022

Okay so basically I have a chat app I made and it appends a paragraph to the chat class which is inside a div which the class chat is a section but when I make enough messages it would put the messages outside the section as in like the background color would only show for a certain amount of messages then just be normal so like the height of it is broken for some reason and I can’t figure out how to fix that.

$('.chat').append('<p id="' + Math.random() + '"><strong style=color:' +
  data.color + '> ' + data.user + '</strong> <span style=color:"black">' +
  data.message + '</span></p>');
