Add Related Posts Widget For Blogger (Based On Labels)

Here I am presenting a new type of Related Posts widget for blogger. It is based on Labels i.e. it shows the results of specific labels/categories you give to your posts. So let's add this quickly to your blog.

How To Add This Widget

1. Go to Blogger Dashboard > Layout > Edit HTML > Download Full Template (for Backup) and click on Expand Widget Templates box.
2. Press CTRL + F and search for ]]></b:skin> 
Add following code BEFORE ]]></b:skin>

<!-- related post -->

.rbbox{border: 1px solid rgb(192, 192, 192);
padding: 5px;
background-color: #f0f0f0;
-moz-border-radius:5px;
margin:5px;
}
.rbbox:hover{background-color: rgb(255, 255, 255);
}
#relpostFs {
border: 1px solid rgb(204, 204, 204);
margin: 0;
padding: 3px 5px;
overflow: auto;
max-height: 200px;
-moz-border-radius:5px;}
<!-- /related post -->

    3. Now look for <data:post.body/>

If you are using "Read More" feature then it will present TWO times. Add following code AFTER Second <data:post.body/>

<!-- related post -->
