Hi Saswata,
As you can see the custom CSS we provide is wrapped inside an @media query
e.g.
@media (max-width: 767px){
}
That means that CSS code will only take effect on screens smaller than 767px
, tablets have slightly bigger screens than that, so you need to adjust that @media query
to suit your needs. Please follow the following link to know more about Media Queries for Standard Devices
Thanks,
