Adding a border around my instagram feed

Hello, 

I would like to make my Instagram feed carousel square and add a border. Can you help?

Hi. Can you share link to page where you added instagram?

I would like this as well -but I want a border around each images, like this -no matter what I try I cant figure it out. Thanks!

If you share site url, we can check easier

Try adding this to Design > Custom CSS

.instagram-block .slide {
    border: 3px solid red;
    width: calc(~"25% - 6px") !important;
    margin-left: -3px;
}
.instagram-block .slide:nth-child(4n+1) {
    margin-left: 0;
}
