In our previous version of dash_core_components (1.6.0) we set the dcc.Loading attribute className='height-100' with the below css. This meant the height of the dcc.Loading div was 100% once loading was complete. This no longer seems to work in dcc 1.10.1.
.height-100{
height: 100%
}
How do we use % heights inside a dcc.Loading?
