Creating A Togglable Bottom Content Panel Using jQuery

A tiny jQuery script for creating a sticky content panel that will pull out from the bottom of the web page when you click the panel tab.

How to use it:

1. Create the Html for a bottom panel.

<div class="panel-wrapper">

<div class="panel-controller">
<div class="tab-controller"> <span class="close">CLOSE PANEL</span> <span class="show">OPEN PANEL</span> </div>
</div>

<div class="panel-content"> 

Panel content goes here

</div>
</div>

2. The CSS rules to style the bottom panel and make it sticky at the bottom of the page.

.panel-wrapper * {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
.panel-wrapper {
position: fixed;
left: 0;
bottom: 0;
overflow: hidden;
width: 100%;
font-family: sans-serif;
}
.panel-controller {
position: relative;
overflow: hidden;
width: 100%;
}
.tab-controller {
float: right;
margin-right: 50px;
padding: 10px 10px 5px;
background-color: #8C293B;
-webkit-border-radius: 15px 15px 0 0;
-moz-border-radius: 15px 15px 0 0;
border-radius: 15px 15px 0 0;
}
.tab-controller * {
display: block;
font-family: sans-serif;
font-size: 16px;
font-weight: bold;
color: white;
cursor: pointer;
}
.tab-controller .show {
display: none;
}
.panel-content {
overflow: hidden;
width: 100%;
background-color: #8C293B;
}

3. Include the jQuery javascript library at the bottom of the document so the pages load faster.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script> 

4. The jQuery script to enable the toggable bottom panel.

(function($) {

jQuery(document).ready(function() {

Panel.init();

$(document).on('click', '.tab-controller', function() {
 Panel.togglePanel();
});

});

var Panel = {

isVisible : true,
showMessage : null,
hideMessage : null,
animationDuration : 650,
animationEasing : 'linear',

init : function() {

},

hidePanel : function() {
$('.panel-wrapper').animate({
bottom : -(Panel.getAnimationOffset())
}, Panel.animationDuration, Panel.animationEasing, function() {
Panel.isVisible = false;
Panel.updateTabMessage();
});
},

showPanel : function() {
$('.panel-wrapper').animate({
bottom : 0
}, Panel.animationDuration, Panel.animationEasing, function() {
Panel.isVisible = true;
Panel.updateTabMessage();
});
},

togglePanel : function() {
((this.isVisible) ? this.hidePanel : this.showPanel)();
},

updateTabMessage : function() {
if (this.isVisible) {
$('.tab-controller .close').show();
$('.tab-controller .show').hide();
} else {
$('.tab-controller .close').hide();
$('.tab-controller .show').show();
}
},

getAnimationOffset : function() {
return $('.panel-content').height();
}

}

})(jQuery);
