Recently Google has release a button similar with the twitter tweet and facebook like buttons. This button is very useful, if you find something interesting on a page you can hit the +1 button and your +1's will help friends, contacts, and others on the web find the best stuff when they search.
If you are already using the official Blogger Sharing buttons, you should already be seeing the +1 buttons on your blog.
If you don't want those buttons an want something like the tweet button just follow the next steps:


1. Log in to your dashboard--> Design- -> Edit HTML

2. Click on "Expand Widget Templates"

3. Search "Ctrl+F" and find the following cod: 
<b:if cond='data:post.title'>
<h2 class='art-postheader'>

4. Now paste the next code after the upper code:

<!-- Google +1 button Start -->
<div>
<g:plusone size="standard" expr:href="data:post.url"/>
</div>
<!-- Google +1  button End -->


To change the style of the button change the red line with:

small for:

5. Then search for </head> and above it paste the next code:

<script type="text/javascript" src="http://apis.google.com/js/plusone.js">

</script>

You can change the language of the button by replacing the red line with your country language code.
Exp:
 French --  fr
Greek --el
German -- de
Romanian -- ro

Italian -- it
Spanish -- es    etc.
