Window content size not affected by Window min -height -width

I'm developing a web application using the Vaadin framework. I have a small problem with modal windows and their content though. As explained in the pictures below:

This is my CSS:

.inventory-switchsubscription-modal-window {
    min-height: 290px;
    min-width: 1060px;
}

Ok, so as you see the window that I have specified in CSS to have a min-height and a min-width is not affected by the resizing, but its content is! Does anyone know of a Window CSS parameter or some other trick I can use to make the CONTENT of the modal window "listen" to the CSS specifications of the window and not resize too small?

Thank you!

Edit: Here's the generated markup and the CSS provided by the Vaadin theme.

    <div class="v-window v-window-inventory-switchsubscription-modal-window inventory-switchsubscription-modal-window" style="margin-left: 0px; margin-top: 0px; left: 429px; top: 365px; z-index: 10001; visibility: visible; position: absolute; overflow: visible; width: 1056px;">

Forgive me for not testing, but pretending that something like this is your markup:

<div class='inventory-switchsubscription-modal-window'>
<div>
<!--content is here-->
</div>
</div>

This should give the div children of the modal window the min height/width

.inventory-switchsubscription-modal-window,
.inventory-switchsubscription-modal-window div, {
    min-height: 290px;
    min-width: 1060px;
}
