media query breakpoints
// Best Practice suggests
// keep default style for smallest screen size (portrait mobile, below 576px)
// and then proceed in assending order with media query like below
// Small devices (landscape phones, 576px and above till next break point)
@media (min-width: 576px) { ... }
// Medium devices (tablets, 768px and above till next break point)
@media (min-width: 768px) { ... }
// Large devices (desktops, 992px and above till next break point)
@media (min-width: 992px) { ... }
// so on ...
