Go to Edit HTML page and find the following line of code:

<b:include data='post' name='comments'/>

Replace the above code with the following:

<b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/>
<b:include data='post' name='comments'/>
</b:if>

Please note: If you found 2 codes lines of given spinet, then you have to replace both.

Now search for ]]></b:skin> and just above that paste the following CSS codes:
