customize share button

Hi,

That could be done with CSS code. If you could provide the website where that sharing button is located, I will see how it is made.

It would have been useful if you could mention the website where the large button is present, so I can see how it is made. On the website you provided there is no such button.

However I tried something similar, like this

.td-post-sharing-bottom .td-social-facebook,
.td-post-sharing-visible {
display: block;
}
.td-social-facebook .td-social-but-icon{
width: 50%;
text-align: right;
}
.td-social-facebook .td-social-but-text{
width: 50%;
text-align:left;
}
.td-social-facebook i,
.td-social-facebook {
font-size: 20px;
}

You could modify the code if needed, then enter it in Theme panel->Custom CSS code section.
