CSS3 and HTML5 Musical Dropdown Menu
Here’s a fresh tutorial by the guys at Script Tutorials about developing a sleek musical dropdown menu with HTML5 and CSS3. This navigation menu has CSS3 animation effects and an HTML5 Audio element was used in adding music to the menu.
Follow the simple steps below:
Step 1 HTML
<ul id="nav">
<li><a href="#">Menu element</a>
<ul>
<li><a href="#">Submenu element</a></li>
.....
</ul>
</li>
<li><a href="#">Menu 4</a></li>
.....
</ul>
Step 2 CSS
#nav,#nav ul {
list-style: none outside none;
margin: 0;
padding: 0;
}
#nav {
font-family: "Lucida Sans Unicode",Verdana,Arial,sans-serif;
font-size: 13px;
height: 36px;
list-style: none outside none;
margin: 40px auto;
text-shadow: 0 -1px 3px #202020;
width: 700px;
/* border radius */
-moz-border-radius: 4px;

background-image: -moz-linear-gradient(center bottom, #787878 0%, #5E5E5E 50%, #707070 51%, #838383 100%);
background-color: #5f5f5f;
}
#nav li {
border-bottom: 1px solid #575757;
border-left: 1px solid #929292;
border-right: 1px solid #5d5d5d;
border-top: 1px solid #797979;
display: block;
float: left;
height: 34px;
position: relative;

}
#nav > li:first-child {
border-left: 0 none;
margin-left: 5px;
}
#nav ul {

}
#nav ul li {
background: none repeat scroll 0 0 #838383;
box-shadow: 5px 5px 5px rgba(0, 0, 0, 0.5);
width: 100%;
}
#nav li a {
color: #FFFFFF;
display: block;
line-height: 34px;
outline: medium none;
text-align: center;
text-decoration: none;
/* gradient */
background-image: -webkit-gradient(linear, left bottom, left top, color-stop(0, #787878), color-stop(0.5, #5E5E5E), color-stop(0.51, #707070), color-stop(1, #838383));
background-image: -moz-linear-gradient(center bottom, #787878 0%, #5E5E5E 50%, #707070 51%, #838383 100%);
background-color: #5f5f5f;
}
/* keyframes #animation */
@-webkit-keyframes animation {
0% {
-webkit-transform: scale(1);
}
30% {
-webkit-transform: scale(1.2);
}
100% {
-webkit-transform: scale(1.1);
}
}
@-moz-keyframes animation {
0% {
-moz-transform: scale(1);
}
30% {
-moz-transform: scale(1.2);
}
100% {
-moz-transform: scale(1.1);
}
}
#nav li > a:hover {
/* CSS3 animation */
-webkit-animation-name: animation;
-webkit-animation-duration: 0.3s;
-webkit-animation-timing-function: linear;
-webkit-animation-iteration-count: 1;
-webkit-animation-direction: normal;
-webkit-animation-delay: 0;
-webkit-animation-play-state: running;
-webkit-animation-fill-mode: forwards;
-moz-animation-name: animation;
-moz-animation-duration: 0.3s;
-moz-animation-timing-function: linear;
-moz-animation-iteration-count: 1;
-moz-animation-direction: normal;
-moz-animation-delay: 0;
-moz-animation-play-state: running;
-moz-animation-fill-mode: forwards;
}
#nav li:hover ul {
left: 0;
top: 34px;
width: 150px;
}
Step 3 HTML and Javascript
Preparing a new empty array to keep audio objects.
// variables var aLoops = []; // sound loops // initialization addEvent(window, 'load', function (event) { // load music files aLoops[0] = new Audio('media/background.ogg'); aLoops[0].volume = 0.3; aLoops[1] = new Audio('media/button.ogg'); aLoops[1].volume = 1.0; aLoops[2] = new Audio('media/button_click.ogg'); aLoops[2].volume = 1.0; aLoops[0].addEventListener('ended', function() { // loop background sound this.currentTime = 0; this.play(); }, false); aLoops[0].play(); }); Adding the handlers to different events – mouseover, mouseout and click // all the buttons var aBtns = document.querySelectorAll('#nav li'); // onmouseover event handler addEvent(aBtns, 'mouseover', function (event) { aLoops[1].currentTime = 0; aLoops[1].play(); // play click sound }); // onmouseout event handler addEvent(aBtns, 'mouseout', function (event) { aLoops[1].currentTime = 0; aLoops[1].pause(); // play click sound }); // onclick event handler addEvent(aBtns, 'click', function (event) { aLoops[2].currentTime = 0; aLoops[2].play(); // play click sound });
