I'm following https://www.w3schools.com/howto/howto_js_off-canvas.asp to create an off-canvas menu.
I was wondering how to change it opening from the left and pushing content towards the right and instead opening from the bottom and pushing content towards the top OR the reverse: opening from the top and pushing content towards the bottom? Basically, I am wondering how to use this example and make it horizontal?
Thanks! :)
