2. 在]]></b:skin>前添加以下CSS代码，Add CSS codes before ]]></b:skin>

/* Label Cloud Styles
----------------------------------------------- */
#labelCloud {text-align:center;font-family:arial,sans-serif;}
#labelCloud .label-cloud li{display:inline;background-image:none !important;padding:0 5px;margin:0;vertical-align:baseline !important;border:0 !important;}
#labelCloud ul{list-style-type:none;margin:0 auto;padding:0;}

#labelCloud a{text-decoration:none}

#labelCloud .label-cloud {}
#labelCloud .label-count {padding-left:0.2em;font-size:9px;color:#000}
#labelCloud .label-cloud li:before{content:"" !important}

3. 定位下列代码，Locate the code below：
<b:widget id='Label1' locked='false' title='Labels' type='Label'/>
......
</b:includable>
</b:widget>

4. 用以下代码替换，Replace the code below：
<b:widget id='Label1' locked='false' title='Label Cloud' type='Label'>
<b:includable id='main'>
<b:if cond='data:title'>
<h2><data:title/></h2>
</b:if>

<div class='widget-content'>
<div id='labelCloud'/>
<script type='text/javascript'>

// Don't change anything past this point -----------------
// Cloud function s() ripped from del.icio.us
function s(a,b,i,x){
if(a>b){
var m=(a-b)/Math.log(x),v=a-Math.floor(Math.log(i)*m)
}
else{
var m=(b-a)/Math.log(x),v=Math.floor(Math.log(i)*m+a)
}
return v
}


var c=[];
var labelCount = new Array();
var ts = new Object;
<b:loop values='data:labels' var='label'>
var theName = "<data:label.name/>";
ts[theName] = <data:label.count/>;
</b:loop>

for (t in ts){
if (!labelCount[ts[t]]){
labelCount[ts[t]] = new Array(ts[t])
}
}
var ta=cloudMin-1;
tz = labelCount.length - cloudMin;
lc2 = document.getElementById('labelCloud');
ul = document.createElement('ul');
ul.className = 'label-cloud';
for(var t in ts){
if(ts[t] < cloudMin){
continue;
}
for (var i=0;3 > i;i++) {
c[i]=s(minColor[i],maxColor[i],ts[t]-ta,tz)
}
var fs = s(minFontSize,maxFontSize,ts[t]-ta,tz);
li = document.createElement('li');
li.style.fontSize = fs+'px';
li.style.lineHeight = '1';
a = document.createElement('a');
a.title = ts[t]+' Posts in '+t;
a.style.color = 'rgb('+c[0]+','+c[1]+','+c[2]+')';
a.href = lcBlogURL+'/search/label/'+encodeURIComponent(t);
if (lcShowCount){
span = document.createElement('span');
span.innerHTML = '('+ts[t]+') ';
span.className = 'label-count';
a.appendChild(document.createTextNode(t));
li.appendChild(a);
li.appendChild(span);
}
else {
a.appendChild(document.createTextNode(t));
li.appendChild(a);
}
ul.appendChild(li);
abnk = document.createTextNode(' ');
ul.appendChild(abnk);
}
lc2.appendChild(ul);
</script>

<noscript>
<ul>
<b:loop values='data:labels' var='label'>
<li>
<b:if cond='data:blog.url == data:label.url'>
<data:label.name/>
<b:else/>
<a expr:href='data:label.url'><data:label.name/></a>
</b:if>
(<data:label.count/>)
</li>
</b:loop>
</ul>
</noscript>
<b:include name='quickedit'/>
</div>

</b:includable>
</b:widget>

5. 回到]]></b:skin>，在其后（但在</head>标签前）添加以下代码，Back to ]]</b:skin>, add these code below(before</head>tag)：
<script type='text/javascript'>
// Label Cloud User Variables
var lcBlogURL = 'http://YOURBLOG.blogspot.com';
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;
</script>

　　最重要的是将YOURBLOG替换成你的blogger id，其他部分可以根据自己的需要作相应的调整。有问题可以留言。
　　The most important is replace "YOURBLOG" to your blogger id, and the rest part you can change depend what you need. If you have any question, you can leave me a message.
