</script>

4.  Now search for ]]></b:skin>  and just above it paste this code,

/*---------- Tabber Start-------- */


.tabberlive{
margin:0;
padding:5px;
clear:both;
background:$tbbxbgcolor;
border:1px solid $tbbxbrcolor;
}
.tabbernav {
margin:0;
padding: 3px 0;
border-bottom: 1px solid $tbbxbrcolor;
font-family:Arial,Helvetica,sans-serif;
font-size:12px;
font-weight:bold;
}
.tabbernav li {
list-style:none;
margin:0;
display:inline;
}
.tabbernav li a {
padding:3px 0.5em;
margin-right:1px;
border:1px solid $tbbxbrcolor;
border-bottom:none;
background:$tbbxcolor2;
text-decoration:none;
color:$tbbxcolor1;
}
.tabbernav li a:hover {
color:$tbbxcolor2;
background:$tbbxcolor1;
border-color:$tbbxbrcolor;
text-decoration:none;
}
.tabbernav li.tabberactive a,
.tabbernav li.tabberactive a:hover {
background:$tbbxcolor1;
color:$tbbxcolor2;
border-bottom: 1px solid $tbbxcolor1;
}
.tabberlive .tabbertab {
padding:5px;
border:1px solid $tbbxbrcolor;
border-top:0;
background:$tbbxcolor1;
}
.tabberlive .tabbertab h2,
.tabberlive .tabbertabhide {
display:none;
}
.tabbertab .widget-content ul{
list-style:none;
margin:0 0 10px 0;
padding:0;
}
.tabbertab .widget-content li {
border-bottom:1px solid $tbbxbrcolor;
margin:0 5px;
padding:2px 0 5px 0;
}


/*------- Tabber End--------*/

5.  Don’t save your template. Now search for Variable definitions and paste this code with other variable definitions,

<Variable name="tbbxbgcolor" description="Tab box Background Color" type="color" default="#f8f8f8" value="#f8f8f8"/>
<Variable name="tbbxbrcolor" description="Tab box Border Color" type="color" default="#dcdcdc" value="#dcdcdc"/>
<Variable name="tbbxcolor1" description="Tab box Color 1" type="color" default="#ffffff" value="#ffffff"/>
<Variable name="tbbxcolor2" description="Tab box Color 2" type="color" default="#5588aa" value="#5588aa"/>

 6.   Now the final part. Search for <div id='sidebar-wrapper'> and paste this code just below it/ or class='column-right-inner'

<div style='clear:both;'/>

<div class='tabber'>
<b:section class='tabbertab' id='tab1' maxwidgets='1'/>
<b:section class='tabbertab' id='tab2' maxwidgets='1'/>
<b:section class='tabbertab' id='tab3' maxwidgets='1'/>
<b:section class='tabbertab' id='tab4' maxwidgets='1'/>
</div>

 7. Finally save your template and visit Layout > Page Elements to start adding widgets to the tabs! It will look something like this,

The widgets are arranged number wise. Starting from Tab-1 and ending at Tab-4. To add a gadget/widget to any tab simply click the link Add a Gadget and start adding whatever you want.

8. Finally view your template to see it hanging!:)
