You can adjust the border and space around your logo from the Edit Business section in your Identity Management templates by going to Manage → Templates → Piano ID Layout → CSS tab and then this section:
.logo {
padding-top: 40px;
background-color: white;
border: 1px solid rgba(0, 0, 0, 0.06);
display: block;
width: 80px;
height: 80px;
object-fit: cover;
text-align: center;
margin: 0 auto;
padding-bottom: 16px;
}
For example, in order to remove the logo's border, you can remove the line border: 1px solid rgba(0, 0, 0, 0.06);.
To remove the whitespace above the logo, you need to remove the line padding-top: 40px;.
