Answer 1

This should do the work

@media only screen and (min-width: 320px)  { body{ font-size: 12px; } }
@media only screen and (min-width: 768px)  { body{ font-size: 14px; } }
@media only screen and (min-width: 1024px) { body{ font-size: 16px; } }
@media only screen and (min-width: 1900px) { body{ font-size: 18px; } }

Answer 2

I love this blog/website, as it is a good resource for CSS3 and nifty tricks:

/* Smartphones (portrait and landscape) ----------- */
@media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
/* Styles */
}

/* Smartphones (landscape) ----------- */
@media only screen
and (min-width : 321px) {
/* Styles */
}

/* Smartphones (portrait) ----------- */
@media only screen
and (max-width : 320px) {
/* Styles */
}

/* iPads (portrait and landscape) ----------- */
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px) {
/* Styles */
}

/* iPads (landscape) ----------- */
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : landscape) {
/* Styles */
}

/* iPads (portrait) ----------- */
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : portrait) {
/* Styles */
}

/* Desktops and laptops ----------- */
@media only screen
and (min-width : 1224px) {
/* Styles */
}

/* Large screens ----------- */
@media only screen
and (min-width : 1824px) {
/* Styles */
}

/* iPhone 4 ----------- */
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
/* Styles */
}

Answer 3

Apply this code.

@media only screen and (max-width:319px)  { body{font-size:11px}}
@media only screen and (min-width:320px) and (max-width:767px)  { body{font-size:12px} }
@media only screen and (min-width:768px) and (max-width:1023px)  { body{font-size:14px} }
@media only screen and (min-width:1024px) and (max-width:1899px) { body{font-size:16px} }
@media only screen and (min-width:1900px) { body{font-size:18px} }
