</script>

Note:

- To change the default picture, replace the URL in pink with your own
- For displaying more than 4 posts or less, replace , modify the value in red (4)
- To change the number of characters to be shown in posts summary, modify the value in blue (75)

5. Now Search the following code:

<a expr:href='data:label.url' rel='tag'><data:label.name/></a><b:if cond='data:label.isLast != &quot;true&quot;'>,</b:if>

6. Just after it, copy and paste the below code:

<b:if cond='data:blog.pageType == &quot;item&quot;'>

    <script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=readpostlabels&amp;max-results=50&quot;' type='text/javascript'/>

  </b:if>

7. Now find the following code:

</b:includable>          
                <b:includable id='postQuickEdit' var='post'>

8. Then copy and paste the below code just above/before it

<b:if cond='data:blog.pageType == &quot;item&quot;'>

  <div class='post-footer-line post-footer-line-4'>

    <div id='relatedpostssum'><div style='text-align: left; font-size: 15px; margin-bottom: 10px; font-weight: bold;'>RELATED POSTS</div>

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

    </div>

    <div style='clear:both;'/>

  </div>

</b:if>

9.  Finally search for this tag:  ]]></b:skin>

10. Add below CSS code just above it,

<relatedsumposts {

  float: left;

  margin: 0px 5px;

  overflow: hidden;

  text-align: center;

  /* width and height of the related posts area */

  width: 120px;

  height: 210px;

}

.relatedsumposts:hover { 

background-color: #F3F3F3; -webkit-border-radius: 10px;

-moz-border-radius: 10px;

border-radius: 10px;

}

.relatedsumposts img:hover {

-khtml-opacity:0.4;

-moz-opacity:0.4;

opacity:0.4;

}

.relatedsumposts a {

  /* link properties */

color: #linkcolor;

  display: inline;

  font-size: 10px;

  line-height: 1;

}

.relatedsumposts img {

  /* thumbnail properties */

margin-top: 2px;

  height: 82px;

  padding: 5px;

  width: 82px;

border: 1px solid #fff;

-webkit-border-radius: 100px;

-moz-border-radius: 100px;

border-radius: 100px;

-webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, .4);

-moz-box-shadow: 0 1px 2px rgba(0, 0, 0, .4);

box-shadow: 0 1px 2px rgba(0, 0, 0, .4);

}

.relatedsumposts h6 {

  /* title properties */

  display: table-cell;

  height: 5em;

  margin: 5px 0 0;

  overflow: hidden;

  padding-bottom: 2px;

  vertical-align: middle;

  width: 130px;

}

.relatedsumposts p {

  /* summary properties */

border-top: 1px dotted #777777;

border-bottom: 1px dotted #777777;

color: #summarycolor;

  font-size: 10px;

  height: 4em;

  line-height: 1;

  margin: 5px 0 0;

  overflow: hidden;

  padding: 5px 0 15px 0;

  text-align: left;

}

Note:

-Modify the values in red to adjust the width (120) and height (210) of the widget area

-Replace #linkcolor with the hex value of your color to change the color of post titles

-To change the size of thumbnails, modify the values marked in pink (82)

-To determine the border roundness, modify the values in green (100)

-To change the color of the post snippet, change #summarycolor with color hex value
