    <!-- UNSELECTED TAB STATE -->
    <item android:state_selected="false" android:state_pressed="false">
        <layer-list>
            <!-- Bottom indicator color for the UNSELECTED tab state -->
            <item android:top="-5dp" android:left="-5dp" android:right="-5dp">
                <shape android:shape="rectangle">
                    <stroke android:color="#65acee" android:width="2dp"/>
