Question

Some other CSS files removed the border around all GWT CaptionPanels. Now I’m looking for a way to add the CaptionPanels border again through the GWT projects .css file. Do you have an idea how to do it? Simply adding a .gwt-CaptionPanel{} to the css file has no effect…

I’m answering my own question here.
It took me some time to figure out that GWTs CaptionPanel uses a fieldset under the hood. The following places a red 1 pixel solid border around GWT CaptionPaneles:

fieldset {
    border: 1px;
    border-style: solid;
    border-color: #ff0000;
}
