Back up your existing Template before making any changes!
Make sure to check the "Expand Widget Templates" box.
Search for the </head> tag.
Add the following code just before the </head> tag.

<style> #related-posts { float : left; width : 540px;
margin-top:20px; margin-left : 5px; margin-bottom:20px; font : 11px
Verdana; margin-bottom:10px; } #related-posts .widget { list-style-type :
none; margin : 5px 0 5px 0; padding : 0; } #related-posts .widget h2,
#related-posts h2 { font-size : 20px; font-weight : normal; margin : 5px
7px 0; padding : 0 0 5px; } #related-posts a { text-decoration : none; }
#related-posts a:hover { text-decoration : none; } #related-posts ul {
border : medium none; margin : 10px; padding : 0; } #related-posts ul li
{ display : block; background :
url("https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhfL5o7ym-OIey9PO3tsHz1RObN_xZQ2t4zqKshXMkFBCKLiVl5Q2G60ZdZgvw5lkbbMySkWuIejOIP4QFmyEF0CuPsPNQJPruUQ542senboFFLc86jqVqz7wZBagJapl8qUF-ISVJkHO4/")

padding-bottom : 1px; padding-left : 21px; margin-bottom : 5px;
line-height : 2em; border-bottom:1px dotted #cccccc; } </style>
<script
src='http://theblogtemplates.com/scripts/Related_posts_hack.js'
type='text/javascript'/>

Now search for <data:post.body/>. In some of the templates this code may look like this

<div class='post-body>

or

<data:post.body/>
Add the following code just beneath the code you just searched for.

<b:if cond='data:blog.pageType == "item"'>

<div id="related-posts">

<font face='Arial' size='3'><b>Related Posts :
</b></font><font color='#FFFFFF'><b:loop
values='data:post.labels'
var='label'><data:label.name/><b:if cond='data:label.isLast
!= "true"'>,</b:if><b:if
cond='data:blog.pageType == "item"'>

<script expr:src='"/feeds/posts/default/-/" +
data:label.name +
"?alt=json-in-script&callback=related_results_labels&max-results=5"'
type='text/javascript'/></b:if></b:loop> </font>

<script type='text/javascript'> removeRelatedDuplicates(); printRelatedLabels();

</script>

</div></b:if>
Now Save your Template and you're done!
