To make changes, you will need to edit both Template files and css files.
For example, in style.css located at , navigate to line 799 and change padding:12px 10px; to padding:1px 2px;
After making the change, remember to hard refresh (Ctrl+F5) to see the result. Alternatively, on line 801, you can adjust margin:0 0 10px; to margin:0 0 2px; and modify width and height to width:80px; height:80px;
You can also add a new line after line 801 to resize images forcibly:
.products-list .product-image img { width:80px; height:80px; }
Remember to update the dimensions of <img> tags in your Template files as well.
If using Firefox, right-click where changes are desired, then Inspect Element to identify the specific element by class or id.
