Images max width/height in posts with css

[Sunka]

What to add in extra.css for max width and height of images inserted through editor image icon?

For xenforo forum posts I have this in my extra.css

.message .messageContent .messageText img {
max-width: 350px;
max-height: 350px;
}

This should work.

.showcaseItem .showcaseItemTabs .messageText img {
max-width: 350px;
max-height: 350px;
}
