Answer 1

This answer requires JQuery.

To hide the #fade_* div: you can use $(#fade_*).delay(delay).fadeOut(); , where delay is the time it takes to hide (animation).

Apply style: display: none to the div you want to have hidden at first.

To show the #light_* div: you can use :

$(#light_*).text('');
$(#light_*).fadeIn("slow").append(message);

where message is the text that will be displayed.

You can create a function to call to make your code readable, like this sample:

<div id="modal">
     <a href="javascript:void(0)" onclick="show_func()"> <!--Your Codes--> </a>
</div>

<script>
     function show_func(){
          $("#modal").hide(); //hide the <div id="modal">

          $("#light_1").show(); //show1
          //or try this one
          document.getElementById("light_1").innerHTML = "Your Codes"; //show2
     }
</script>
