How to Add Official Twitter Follow Button to Blogger Blog

Demo - Feel free to click as much as you want because there is no account linked with this button. 

1. Log into blogger
2. Now search for this code (CTRL+F):

<data:post.body/>

3. Just above him, add next code:

<div style="float:right;padding:4px;">
<a href='http://twitter.com/share' rel='nofollow' class='twitter-share-button' expr:data-url='data:post.canonicalUrl' expr:data-text='data:post.title' data-related='adasdasd:' data-count='vertical' data-via='asdadsdasdsaasasdas'  data-lang='en'></a>
<b:if cond='data:post.isFirstPost'>
<script type="text/javascript" src="http://platform.twitter.com/widgets.js">
</script>
</b:if>
</div>

Now, if you wana change the side or custom, search this or similar codes: 

"float:right;

Change to "left" or 'vertical' to 'horizontal' - if you want to see counter like here on demo.
Click save and that should be it. Happy Blogging friends.
