Vertical Social Icons – Summary Block

To make Social Icons vertical, you can follow these.
#1. Social Links Block
First, find Social Links Block ID.
In my example, it is: #block-yui_3_17_2_1_1730073565059_12902

Next, use this code to Custom CSS box.

#block-yui_3_17_2_1_1730073565059_12902 {
    nav {
    flex-direction: column;
}
    nav a {
        margin-top: 10px;
        margin-bottom: 10px;
    }
}
