Blogger Trick

This simple trick will help you to modify the avatars size in Blogger comments. For changing the style and size of avatars, we have to add some CSS codes in our Blogger template. So, let's begin:


Step 1.

Go to Dashboard - Template - click on the Edit HTML button - Proceed


...now select Expand Widget Template (I recommend to make a backup first)

Step 2. Find (CTRL + F) this code in your template:

]]></b:skin>

Step 3. Copy and paste one of the following codes just above it:

[Works in Blogger threaded comment system]

.comments .avatar-image-container{
background-color: rgb(34, 34, 34);
border:1px solid #ccc;
margin: 0px 10px 0px 0px;
padding: 0px 0px 0px 0px;
width: 64px;
max-height: 64px;
}
.comments .avatar-image-container img{
margin: 0px 0px 0px 0px;
padding: 0px 0px 0px 0px;
max-width: 64px;
height: 64px;
}

[for old blogger commenting system]

.avatar-image-container{
border:1px solid #d6d6d6;
margin-left: -30px;
-moz-border-radius: 4px;
background:#fff;
height:70px;
min-height: 70px;
width:70px;
min-width:70px;
}
.avatar-image-container img {
background: url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiQmSPsYnyy7Av5HgXGeo43yFWJMtI3QINs74s_Pbzlm9TmVLagFYCoMzz8HKvA1zS3JNTcRHgmlUTfOeYj4Bs2nkABMT9ssAJMcpZB0xekpFlML_pgU9foYaMko8Jct3FEpNAOeHKQqTI/s200/anonymous.jpg);
background-repeat: no-repeat;
background-position: center;
background-size: 100%;
width:70px;
min-width:70px;
height:70px;
min-height:70px;
}

Note: If you want bigger/smaller avatars, change the values in red. To change the anonymous avatar, replace the URL address in blue with your own. (works only for previous commenting system)

Step 4. Save the Template.

Now view your blog to see the results. Hope you enjoy!
