/* Team */
.team-item .team-triangle {
width: 90px;
height: 90px;
}
.team-triangle .content {
width: 160px;
height: 160px;
}
.team-hover i {
margin-top: 50px;
}
.team-hover p {
font-size: 14px;
}
/* Medium Devices, Desktops */
#media only screen and (max-width : 992px) {
/* Team */
.team-item .team-triangle {
width: 120px;
height: 120px;
}
.team-triangle .content {
width: 190px;
height: 190px;
}
.team-hover i {
margin-top: 57px;
}
#team-section .col-md-2:nth-child(7n+5),
#team-section .col-md-2:nth-child(7n+1){
margin-left: 0 !important;

Answer 1

Maybe you want something like this.
.large-gutter > [class*='col-'] {
padding-right:50px;
padding-left:50px;
}
HTML
<div class="row large-gutter">
<div class="col-md-4">
...
</div>
<div class="col-md-4">
...
</div>
<div class="col-md-4">
...
</div>
</div>
