You might not like Mashshare buttons so close to each other and you might want to add some spacing between each button.
If that’s your aim, please use these custom CSS rules below and add them to Mashshare Settings -> Customisation -> Custom Styles;
.mashsb-buttons > a[class^='mashicon-'] {
margin-right:10px;
}
.mashsb-buttons > a[class^='mashicon-']:last-of-type {
margin-right:0;
}
