Could someone help me to realize or better the following functions,
1.header 100% wide.(using [[windows.width]], done)
2.sidebar 100% high.(using, [[windows.height]], done)
3.when sidebar folded to the left, header (and content below ) still 100% wide(take sidebar’s space). (using show/hide toggle, done)
4.no matter how header stretched horizontally, buttons in it would stay the same relative position of the edge.
