Hi Denny,

You can add VK social network, add the link to that social network but change the VK icon to Whatsapp icon.

To do that you just need to add this CSS code:

.fa-vk:before {
    content: "\f232";
}

in the Custom CSS area.

For more info please see this video.

Have a great day!

Hi Denny,

I can see that this code increases icon size, you can do that very easy with CSS without modifying a single theme code.

To do that is very easy, please just see this video.

If you need the CSS code that I used in the video here it is:

ul.social-networks li a {
    line-height: 55px;
    -webkit-border-radius: 50px;
    -moz-border-radius: 50px;
    border-radius: 50px;
    width: 50px;
    height: 50px;
}
ul.social-networks li a i {
    font-size: 25px !important;
}

Anyway, if you need that area then you can find the file in this area wp-content/themes/oxygen/inc/laborator_filters.php

Have a nice day!

P.S: Please be aware as by doing customization if something happens like miss-editing files the responsibility is yours and we won't support you on finding the problem, as we are only guiding you how to get the results you need.
