Hello. Post block with buttons to share in social networks from Yandex. He gives this code:
<div class="ya-share2" data-services="collections,vkontakte,facebook,odnoklassniki,moimir"></div>
In the page code already compiles a list with links. I understand the buttons themselves are formed already during page load. Can we get to each link separately and prescribe her a rel="nofollow"?
