My jquery for creating the HTML will be ,

function send(name , message , time){
    //name = $("#name").val();
    //message = $("#message").val();

    var user = "<div id='user' class='fontStyle'>"+name+"</div>";
    var msg = "<div id='msg'  class='fontStyle'>"+message+"</div>";

You can escape html your string so it keeps the white spaces. See details here .

Or you can trim your message string (=remove spaces at the beginning and end of it) with such an instruction, and then manualy add the spaces (with the   code inside a div, span, ...):

s.replace(/\s+/g, ' ');
