Social share icon – VK.com

Good day.
I need to add a new button to share VK.com
I add to the file td_module_single.php a new line:

<div class="td-sp td-sp-vk"></div><div class="td-social-but-text">VK.com</div>

Next, I add code in file style.css:
.td-social-vkontakte {
background-color:#507299;
}
.td-social-vkontakte .td-social-but-text {
border-left: 1px solid rgba(255, 255, 255, 0.25);
}
/* responsive portrait phone */
@media (max-width: 374px) {
.td-social-vkontakte .td-social-but-text {
display: none;
}
}
But no text and no icons. Tell me what I’m doing wrong

here is the code which I added to the file td_module_single.php
