How Do I Remove Gray Frame on my Like To Know It Widget and make it square

Hello!!

I am using LTK shop widget on my blog. I'd like to remove this ugly gray frame and be able to have the images be square and centered as well as use my own font  to write a product description below.

This is the only thing I found online that describes exactly what i want to do (It's for Wordnpress unfortunately)https://help.empressthemes.com/article/287-remove-gray-frames-from-rewardstyle-product-thumbnails-and-force-each-thumbnail-to-a-square-size-boutiques

This is the code LTK gives me to add to my website via block

<div class="boutique-widget" data-widget-id="1170496"><script type="text/javascript">!function(w,i,d,g,e,t){d.getElementById(i)||(element=d.createElement(t),element.id=i,element.src="https://widgets.rewardstyle.com"+e,d.body.appendChild(element)),w.hasOwnProperty(g)===!0&&"complete"===d.readyState&&w[g].init()}(window,"boutique-script",document,"__boutique","/js/boutique.js","script")</script><div class="rs-adblock"><img src="https://assets.rewardstyle.com/production/758f49dc51189befd7ec513a0d5e6b380413022e/images/search/350.gif" onerror='this.parentNode.innerHTML="Disable your ad blocking software to view this content."' style="width: 15px; height: 15px"><noscript>JavaScript is currently disabled in this browser. Reactivate it to view this content.</noscript></div></div>

This is how it looks on my website:

This is how I'd like it to look: white square blocks with custom font description below
