MessageBox Panel (How to add resizable Text container?)

Hello, For now I have simple MessageBox container to display game messages (for example, killed monster etc.).

My hierarchy is:

1)Panel

1a)Panel (Mask + Scroll Rect)

1ab)Panel (Vertical Layout Group + Content Size Filter + LogConsole Script)

1b)Scrollbar

LogConsole Script:

 public class LogConsole : MonoBehaviour {
 
     public GameObject Line;
     List<GameObject> Messages;
     int LineCount = 0;
 
     void Start () {
         Messages = new List<GameObject>();
     }
 
     public void LogMessage(string message)
     {
         GameObject line = (GameObject)Instantiate(Line);
         line.transform.SetParent(this.transform);
         line.name = "Message" + LineCount;
         line.GetComponent<Text>().text = System.DateTime.Now.ToString() + ": " + message;
         Messages.Add(line);
         if(LineCount >= 30){
             Destroy(Messages[0]);
             Messages.RemoveAt(0);
         }
         LineCount++;
     }
 }

Everything works great, but I wonder, how I can make that Text container to be sized automatically? cus Small messages have huge ugly spaces, and big messages do not wrap. look screen: http://screenshooter.net/102644289/omykrny
