How to restyle the draggers of the SplitLayoutPanel in GWT UIBinder template - gwt

Question

can anyone tell me how I can change the style of the draggers in a UIBinder template for the SplitLayoutPanel.
Here is my MainMenu.ui.xml:
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
xmlns:g="urn:import:com.google.gwt.user.client.ui">
<ui:style src="Resources/GlobalStyles.css" />
<g:SplitLayoutPanel width="100%" height="100%" styleName='{style.splitLayoutPanel}'>
<g:north size="100">
<g:HTMLPanel/>
</g:north>
<g:west size="250">
<g:HTMLPanel/>
</g:west>
<g:center>
<g:HTMLPanel/>
</g:center>
<g:south size="50">
<g:HTMLPanel
styleName='{style.footerPanel}'>
<div>

</div>
</g:HTMLPanel>
</g:south>
</g:SplitLayoutPanel>
</ui:UiBinder>
The Resources/GlobalStyles.css looks like this:
body,table {
font-size: small;
}
body {
font-family: Helvetica, Arial, sans-serif;
color: #000;
background: #red;
}
.splitLayoutPanel {
.gwt-SplitLayoutPanel-HDragger {
background:#d0e4f6;
cursor: col-resize;
}
.gwt-SplitLayoutPanel-VDragger {
background: #d0e4f6;
cursor: row-resize;
}
}
.footerPanel {
margin-left: 11px;
padding: 10px;
border-top: 2px solid #5693d6;
text-align: right;
}
What's wrong here? My draggers are not visible and there is no cursus change.

I think GWT doesn't like the nesting. So rewritting the css as follows should make it work:
.splitLayoutPanel .gwt-SplitLayoutPanel-HDragger {
background:#d0e4f6;
cursor: col-resize;
}
.splitLayoutPanel .gwt-SplitLayoutPanel-VDragger {
background: #d0e4f6;
cursor: row-resize;
}
Also GWT will probably complain about the .gwt- styles, in that case the following lines in your css:
#external .gwt-SplitLayoutPanel-HDragger;
#external .gwt-SplitLayoutPanel-VDragger;
