how to add and remove css class

Question

how to remove CSS default class

This is my div

This is my css class

#messageContai         


        

Answer 1

You are not defining a css class in your example, you are using the selector for the id.

to use a class your code would be like:

and in your stylesheet or between style tags you would have

.messageContainer{  
  height:26px;  
  color:#FFFFFF;    
  BACKGROUND-COLOR: #6af; 
  VERTICAL-ALIGN: middle;
  TEXT-ALIGN: center;
  PADDING-TOP:6px;  
}

then, using jquery you could remove this class by doing

$('#messageContainer').removeClass('messageContainer');
