Is it possible to nest media queries within media queries? - css

Question

Is this possible? It seems like a neat solution to me, but I'm not sure if it will work.
#media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
/* Code for both portrait and landscape */
#media (orientation:portrait) {
/* Code for just portrait */
}
#media (orientation:landscape) {
/* Code for just landscape */
}
}

Answer 1

You should be able to nest #media rules this way in CSS3, but it isn't yet supported by most browsers. See this answer for details.
You would have to fully expand and repeat the top-level media queries for the inner rules for it to work across browsers (and I imagine the SCSS processor would generate something similar):
#media only screen
and (min-device-width: 320px)
and (max-device-width: 480px) {
/* Code for both portrait and landscape */
}
#media only screen
and (min-device-width: 320px)
and (max-device-width: 480px)
and (orientation: portrait) {
/* Code for just portrait */
}
#media only screen
and (min-device-width: 320px)
and (max-device-width: 480px)
and (orientation: landscape) {
/* Code for just landscape */
}

Answer 2

If you wanted to do this the best way is to use the high level media query in a link tag, and then the other queries inside the linked sheet.
In practice though most people cascade their CSS rules from a base sheet that covers the common stuff and then putting changes to that in each media rule-set.

Answer 3

I think not possible but you can write this format If you are using SASS css pre-processor.
example , you can copy this code and paste to https://www.sassmeister.com/ -and watch the output
SASS
#media only screen and (max-width: 767px) {
body{
color:red;
}
#media (orientation:portrait) {
body{
color:green;
}
}
#media (orientation:landscape) {
body{
color:orange;
}
}
}
Output CSS
#media only screen and (max-width: 767px) {
body {
color: red;
}
}
#media only screen and (max-width: 767px) and (orientation: portrait) {
body {
color: green;
}
}
#media only screen and (max-width: 767px) and (orientation: landscape) {
body {
color: orange;
}
}
