Hello @philysgdy,
For your image, since there is no option in the image element settings, you will have to resort to inserting a custom inline element CSS. For example, you can use @media to target which screen sizes will the CSS be applied. Take this code for example:
@media(min-width:980px) and (max-width: 1280px){
$el.x-image {
min-width: 230px;
max-width: 280px;
}
}
The code above will set the minimum width of 230 pixels up to 250 pixels only. Feel free to make adjustment as you need. Here are some related links for further reading, this could help you in finding and implementing some CSS fixes:
