I do not get it

My first effort to style tinymce did for some parts work.
I am styling a modal window that pop up when I click “insert image”
I want to hide all fields in that modal except for the fileupload source field. (of course)
I managed to hide the fields using my default stylesheet.
But I could not change the modals dimensions to make the box smaller, like I could in browser inspector tool. I do think I know why, because the css is loaded later?

So I installed your plugin that generates a css file. Inserted the same styling. Yet the result was the same as when I used my default stylesheet, it ignored my attempt to set the height.

customeditor-style-shared.css :

...

/* Append your site-specific styles here */

// This did not work (modal box)
div#mceu_38-body.mce-container-body.mce-window-body.mce-abs-layout{
    height: 74px;
}

div#mceu_38.mce-container.mce-panel.mce-floatpanel.mce-window.mce-in{
    height: 156px;
}

//This worked, I hid the fields and labels

div#mceu_53-body.mce-container-body.mce-abs-layout{
    display: none;
}
div#mceu_71-body.mce-container-body.mce-abs-layout{
    display: none;
}

div#mceu_52.mce-container.mce-abs-layout-item.mce-formitem{
    display: none;
}

Hope I made sense ??
