I am finding it hard to understand the Following :
Globally, you may alter the size of x vs y drawers with the following variables:
$bmd-drawer-x-size $bmd-drawer-y-size
What does it mean ? I am refering to the Following Link. http://rosskevin.github.io/bootstrap-material-design/material-design/drawers/#customization.
All i want to achieve is to increase the Size of the Drawer.
If I understood correctly, you can increase the size of left, right (horizontal) drawers using $bmd-drawer-x-size and top, bottom (vertical) drawers using $bmd-drawer-y-size.
You need to edit the SASS variable and update it, or override it from different file
