下面的代码只会更改面板周围边框的颜色,而不会更改面板本身的颜色.

var overlay = Ext.Viewport.add({                
    xtype: 'panel',
    centered: true,
    style:'background-color: transparent;',
    modal: {
        style: 'opacity: 0'
    },
    hideOnMaskTap:true,
    width:'20%',
    height: '50%',
    styleHtmlContent:true,
    items:[{
        xtype:'button',
        test:'hey',
        cls:'notrans',
        style: 'opacity: 1'
    }]
});
