Nowadays, UX is a key factor when it comes about creating/designing a product or system. To keep users happy, developers struggle to create a good experience and a better interactivity. UX is a term used to describe the overall experience and satisfaction a user has when using a product or system. So, a good UX will always make users happy and businesses more successful. Notification messages are an important part of the user experience and you can’t afford to omit them. A notification alert message should appear every time the user perform important tasks.

The CSS

.message{
     -webkit-background-size: 40px 40px;
     -moz-background-size: 40px 40px;
     background-size: 40px 40px;
     background-image: -webkit-gradient(linear, left top, right bottom,
                color-stop(.25, rgba(255, 255, 255, .05)), color-stop(.25, transparent),
                color-stop(.5, transparent), color-stop(.5, rgba(255, 255, 255, .05)),
                color-stop(.75, rgba(255, 255, 255, .05)), color-stop(.75, transparent),
                         to(transparent));
     background-image: -webkit-linear-gradient(135deg, rgba(255, 255, 255, .05) 25%, transparent 25%,
                         transparent 50%, rgba(255, 255, 255, .05) 50%, rgba(255, 255, 255, .05) 75%,
                         transparent 75%, transparent);
     background-image: -moz-linear-gradient(135deg, rgba(255, 255, 255, .05) 25%, transparent 25%,
                         transparent 50%, rgba(255, 255, 255, .05) 50%, rgba(255, 255, 255, .05) 75%,
                         transparent 75%, transparent);
     background-image: -ms-linear-gradient(135deg, rgba(255, 255, 255, .05) 25%, transparent 25%,
                          transparent 50%, rgba(255, 255, 255, .05) 50%, rgba(255, 255, 255, .05) 75%,
                          transparent 75%, transparent);
     background-image: -o-linear-gradient(135deg, rgba(255, 255, 255, .05) 25%, transparent 25%,
                          transparent 50%, rgba(255, 255, 255, .05) 50%, rgba(255, 255, 255, .05) 75%,
                           transparent 75%, transparent);
     background-image: linear-gradient(135deg, rgba(255, 255, 255, .05) 25%, transparent 25%,
                           transparent 50%, rgba(255, 255, 255, .05) 50%, rgba(255, 255, 255, .05) 75%,
                            transparent 75%, transparent);
     -moz-box-shadow: inset 0 -1px 0 rgba(255,255,255,.4);
     -webkit-box-shadow: inset 0 -1px 0 rgba(255,255,255,.4);
     box-shadow: inset 0 -1px 0 rgba(255,255,255,.4);
     width: 100%;
     border: 1px solid;
     color: #fff;
     padding: 15px;
     position: fixed;
     _position: absolute;
     text-shadow: 0 1px 0 rgba(0,0,0,.5);
     -webkit-animation: animate-bg 5s linear infinite;
     -moz-animation: animate-bg 5s linear infinite;
}
.info{
     background-color: #4ea5cd;
     border-color: #3b8eb5;
}

.error{
     background-color: #de4343;
     border-color: #c43d3d;
}

.warning{
     background-color: #eaaf51;
     border-color: #d99a36;
}

.success{
     background-color: #61b832;
     border-color: #55a12c;
}

.message h3{
     margin: 0 0 5px 0;
}

.message p{
     margin: 0;
}

@-webkit-keyframes animate-bg{
    from {
       background-position: 0 0;
    }
    to {
       background-position: -80px 0;
    }
}

@-moz-keyframes animate-bg{
    from {
       background-position: 0 0;
    }
    to {
       background-position: -80px 0;
    }
}

Note the animate-bg, which animate the background diagonal stripes. Of course, to see this effect, you should use latest Webkit browsers like Chrome/Safari or Mozilla 5+. The notification messages will be hidden initially. For that we’ll use fixed positioning (absolutevalue just for IE6 – as there is no position:fixed support).

    position: fixed;
     _position: absolute; /* IE6 only */

The jQuery

Define the messages types using an array:

var myMessages = ['info','warning','error','success'];

The below function hides the notification messages. Messages could have dynamic heights and for that, each message’s height is calculated in order to hide it properly.

function hideAllMessages(){
         var messagesHeights = new Array(); // this array will store height for each
         for (i=0; i<myMessages.length; i++){
                   messagesHeights[i] = $('.' + myMessages[i]).outerHeight(); // fill array
                   $('.' + myMessages[i]).css('top', -messagesHeights[i]); //move element outside viewport
         }
}

The showMessage function is called when document ready.

function showMessage(type){
        $('.'+ type +'-trigger').click(function(){
                  hideAllMessages();
                  $('.'+type).animate({top:"0"}, 500);
        });
}

On page load, first of all we’ll hide all the messages: hideAllMessages(). Then, for each trigger, show the equivalent message:

$(document).ready(function(){
                 // Initially, hide them all
                 hideAllMessages();

                 // Show message
                 for(var i=0;i<myMessages.length;i++){
                        showMessage(myMessages[i]);
                 }

                 // When message is clicked, hide it
                 $('.message').click(function(){
                                  $(this).animate({top: -$(this).outerHeight()}, 500);
                  });            
});

Conclusion

Using CSS3, I think you can find endless possibilities to design notification messages. The above is just a minimal example, with no images (for simplicity’s sake). But, the design is not everything, as functionality and interactivity have a very important role here.

Updates

  • Added CSS3 animation support for Mozilla 5+. I also fixed the proper CSS3 animation.
  • CSS3 gradients syntax updated. Now, Safari also renders background stripes.

  1. The only thing I would like to know now is how to make the cool notification go away when someone clicks elsewhere on the document or presses the ESC key. Is that hard to add?

  2. This is a really good tip especially to those new to the blogosphere.
    Brief but very accurate information… Appreciate your sharing this one.
    A must read post!
