im using the "related posts" plugin in WP but the thumbnail container resizes with the image like this:

i want to add a custom css to prevent the container from resizing and to stay fixed no matter the image size. i want all the thumbnail containers to be the same width and height. FYI the image comes from the posts featured image.
