I try to make my own colered buttons (TUniSpeedButton). The normal and hover colors are OK, but the active color not. My CustomCSS looks like this: .btnMenu {border-radius:5px; background-color: rgb(211,235,225) !important; border: 1px solid rgb(142,28,36); } .btnMenu:hover {background-color: rgb(168,215,194) !important; } .btnMenu:active {background-color: rgb(131,199,170) !important; } Mainform.OnCreate: btnNieuws.ClientEvents.ExtEvents.Values['afterrender']:= 'function afterrender(sender, eOpts)'#13#10'{'#13#10' sender.addCls('#39'btnMenu'#39') ;'#13#10'}';
