The gape

Hey there
you can use percentage instead of using height or width in pixels so it will be adjusted according to your device.

Not working for all devices

When you use a percentage factor, it will display the content based on that percentage of the device’s size.
For example, you are using 50% height it will show content on half screen of each device you are using.
