Make sure you backup your template before making any changes! Log into Blogger and go to your layouts section. On the ‘Page Elements’ setup page
make sure you have a label widget already installed where you want it (it can be moved around later). Then go to the Edit HTML settings and leave the widgets NOT exapanded. It will make things easier to deal with.

Now the code comes in 3 parts. A section for the stylesheet, a configurations section, and then the actual widget itself.

The first part to put in is the stylesheet section. The following code needs to be copied and inserted into your stylesheet, which in the layouts is marked out by the <b:skin> tags.

Easiest thing to do is find the closing skin tag:

]]></b:skin>

and place the code right BEFORE that. Here it is, copy and paste without modification right now. I’ll explain what can be tweaked later.

/* 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 img{border:0;display:inline;margin:0 0 0 3px;padding:0}
#labelCloud a{text-decoration:none}
#labelCloud a:hover{text-decoration:underline}
#labelCloud li a{}
#labelCloud .label-cloud {}
#labelCloud .label-count {padding-left:0.2em;font-size:9px;color:#000}
#labelCloud .label-cloud li:before{content:”" !important}

This next section is the configuration section for the Cloud. It also goes in the head of the template, but outside of the stylesheet part. Easiest thing to do again is to find the closing stylesheet tag:

]]></b:skin>

But this time place the code right AFTER that line, but BEFORE the </head> tag. Here it is.

<script type=’text/javascript’>
// Label Cloud User Variables
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;
</script>

All of these settings can be changed but I’ll explain them in a moment. The defaults will work for now.

Now the widget itself. Scroll down and find the label widget in your sidebar. It should look something like this.

<b:widget id=’Label1′ locked=’false’ title=’Labels’ type=’Label’/>

Copy the following code (from beginning widget tag to ending widget tag) and replace the line above with it.

Now if all has gone well, and you have posts already labeled, then if you preview the blog you should see some form of the Cloud appearing. If it doesn’t appear, then something went wrong. You should probably back out and try it again from the start.

Update : I’ve found 2 things to check for first if the label cloud isn’t showing. First make sure that at least one of your labels has more than one entry. A bug in the script causes it to fail when all the labels have only one entry.(As soon as any label has more than one entry, then it should be ok from then on) Also, make sure that none of your labels contain quote marks ” . Most likely the cloud with it’s default settings won’t be what you ultimately want. But all the colors and sizes are configurable to match your tastes. If the cloud is appearing in preview then you can go about changing some of the variables so they suit.

The settings in the Variables section will be where you make most of your adjustments. Here I’ll explain what each setting does.

var cloudMin= 1;

This setting you can use to limit the number of labels shown (for example if you have a lot of labels). Leave the setting at 1 to show ALL labels. If you enter in a higher number, then only labels that have at least that number of entries will appear in the cloud.

var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;

The lines for:

1. maxFontSize
2. maxColor

Do what you may think they do. The first one sets the size (in pixels) of the label with the most amount entries. The maxColor sets the color of that entry (in RGB format). Similiar with the next two

1. minFontSize
2. minColor

Just these are for the label with the least amount of entries. Again the size is in pixels, the color is in RGB format. Any labels between the two will get their color/sizes based on how many labels they are, and where their entry count falls, giving the much desired cloud effect.

From my experimenting, there are many factors that make up a pleasant looking cloud. From color/size choice, to the number of actual labels, to how well dispersed the entries are amoung the labels. 3 Labels don’t make a good cloud as there isn’t much to work with. You just have to experiment around to see what looks good with your setup.

IMPORTANT, when change the color settings, Keep them in the format supplied. In between the [] and the numbers separated by commas. The default colors are BLUE for the max and BLACK for the min.

You can select any valid RGB color combination. If you don’t know what RGB colors are, don’t worry. It’s just a way of defining a color. You can use many charts on the Internet to get the correct RGB value for the color you want to try. Here’s one that is fairly good.

RGB Color Code Chart Remember, if you get the 3 sets of numbers to enter them in correctly. Inside the [ ] separated by commas.

Also experiment with different font sizes. Again it depends on how many entries, how dispersed they are, and how much room for the cloud is available as to what looks good.
The last variable there is

lcShowCount

This can either be false (default) or true. All this does is turn off/on the post count displayed
next to the label. Usually in a ‘traditional’ cloud the count isn’t used. But if you go to a
‘flat’ listing then it’s sometimes useful to turn it on.

Now to the CSS section. Most people won’t need to tweak these much, and it’s not necessary to
understand what all those entries are for. Most are just to make sure that other styling
elements from the rest of your page don’t inherit in and ruin the cloud. But there are a few
that you may want to change to suit.
The first line

#labelCloud {text-align:center;font-family:arial,sans-serif;}

You could change the fonts used in the cloud here if you wanted.
Also, the text-align statement can also be changed. I have it set to center by default but you
could use

text-align:justify;
text-align:right;
text-align:left;

If those suit better.

The next line

#labelCloud .label-cloud li{display:inline;background-image:none !important;padding:0 5px;margin:0;vertical-align:baseline !important;border:0 !important;}

Well don’t worry about most of it unless you are a hardcore CSS’er. The only one of real
importance is the first entry

display:inline;

You can change that to

display:block;

To get the ‘Flat’ (each entry on it’s own separate line) listing of the weighted entries.
Usually if that is set to block you would probably want to change the sort frequency from
alphabetical to frequency. You do that by editing the widget from the Page Elements tab in
Blogger.

And the last bit I’ll mention is the line

#labelCloud .label-count

If you set the lcShowCount variable to true to show the post counts, you could change the
color/size of those numbered entries with that line.

Tag Clouds (provided they are not cluttered and display just the relevant words) help visitors quickly visualize what your website is all about since the topics you frequently cover are mentioned in bold or relatively bigger fonts.

WordPress community already offers some excellent plugins for generating tag clouds (like the Ultimate Warrior) plus the upcoming release, WP 2.3, has inbuilt support for tagging.

However, if you are on Blogger or have a non-blog website, there’s no reason that you should miss Tag Clouds.

Here’s how to add a good looking tag cloud to your Blogger blog:

1. Type your Blogger feed address in google feed:

http://www.blogger.com/feeds/XXX/posts/default?max-results=542

Remember to replace XXXwith your Blog ID. This URL will retrieve your latest 542 posts and supply that for analysis to Feed.

2. For the word link, type the following (where name is your blog name, e.g. w3code)

http://name.blogspot.com/search?q=%%enc_word%%

3. You can change the default font size, tag cloud dimension background image and colors to fit your site theme.

4. Now the tricky part. Once you have generated the tag cloud using Feed, right click over your tag cloud and click “View HTML source” – that the code you need to copy paste in your site.

Tip for Tag Clouds – If you really want visitors to spend more time on your site via Tag Clouds, always keep the number of words in Tag Cloud to an absolute minimum and that there is sufficient space around each word.

You can see a good implementation of this label cloud widget on one of our readers blog -Speak Media Blog.
First Of all Goto Your blogger Layout>Page Elements page and add a Labels Widget there..You can Do that using the Add a Page Element Option on that Choose to sort the labels Alphabetically when prompted.

After Adding the Label Widget Goto Layout>Edit Html (Do not expand the widget templates for the sake of easy explanation)

You will find some code similar to:

<b:widget id=’Label1′ locked=’false’ title=’Labels’ type=’Label’/>

Now Replace that with:

View this content

Next find :

]]></b:skin>

…and replace it with:

#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 img{border:0;display:inline;margin:0 0 0 3px;padding:0}
#labelCloud a{text-decoration:none}
#labelCloud a:hover{text-decoration:underline}
#labelCloud li a{}
#labelCloud .label-cloud {}
#labelCloud .label-count {padding-left:0.2em;font-size:9px;color:#000}
#labelCloud .label-cloud li:before{content:&quot;&quot; !important}
]]></b:skin>

Save your template and now you should get a working Label Cloud On your Blog.

1. Login in blogger .com

2. Posting – Edit Posts

3. Choose Labels want to remove or change this.

4.
Finaly, I’d conclude this short more:

1. Click the “Books” label link on the left side of the page.
2. Click the “Select All” link at the top of the list of posts.
3. From the “Label Actions…” menu, choose “Remove label > Books.”
4. From the “Label Actions…” menu, choose “Apply label > New Label…”
5. Enter “Reading” as your new label. (If you already have some posts with the label “Reading,” you can simply apply that label, without making a new label.)

Choose to sort the labels Alphabetically when prompted.

After Adding the Label Widget Goto Layout>Edit Html (Do not expand the widget templates for the sake of easy explanation)
