custom CSS help – drawer

Hi, I would like to add a thin grey border around each image in this drawer set up – the CSS I’m trying is below, the padding seems to work but nothing else, thank you

.drawer-style.style-1 figure {
border-style: solid;
padding: 10px 10px 10px 10px;
}

img {
padding: 10px 20px 10px 20px;
border-style: solid;
border-width: 1px;
border-color: grey;
}
