I have created external CSS file and add media query to it for different screen sizes that is given in appery.io browser like 240 X 320, 320 x 480 so on. CSS Media query is working if app is testing in Appery.io browser but it doesnt work if testing an app in android phone.
I am struggling since a week 
try to use !important?
like this:
@media screen and (min-height: 451px) and (max-height: 600px) {
.maps {
height:250px !important;
}
}
Thanks !
But i have use important already in my css like :
@media only screen and (min-width : 320px) and (max-width : 399px) and (orientation : portrait) {
.hsa_your_annual_contribution_mobilelabel_3
{
top: 33% !important;
left: 22% !important;
font-size: 12px !important;
}
}
hmm get rid of: only
@media screen and (min-width : 320px) and (max-width : 399px) and (orientation : portrait) {
.hsa_your_annual_contribution_mobilelabel_3
{
top: 33% !important;
left: 22% !important;
font-size: 12px !important;
}
}
are u sure u have the correct class name on ur label?
otherwise i dont know 
yes of course ! It is just a snippet of media query, i have used media query on other pages too that also not working.
Hi Shalu,
You can test media query with following way(step - by - step instruction):
Create new CSS asset in your app.

Populate it with following CSS code:

pre
@media screen and (max-width: 1000px) {
[data-role="content"] {
background: url(http://mypets.kiev.ua/sites/default/files/admin/59_13.jpg);
background-size: cover;
}
}
/pre
Run app without frame(to have ability to change document size):.

Make browser more then 1000px by width, you have app without background.

After correct test - you can change inside styles.
