You may wish to try copying the list of media queries from your parent style.css onto your child, then modify them. Here’s what is working for me so far…
@media screen and (max-width: 400px) { /* includes Galaxy s4 and iphone 5 portrait */
{enter style here}
}
@media screen and (min-width: 401px) { /* includes Galaxy s4 and iphone 5 landscape */
{enter style here}
}
@media screen and (min-width: 594px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 673px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 783px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 810px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 846px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 1008px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 1040px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 1080px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 1110px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 1218px) {
/* YOUR STYLE GOES HERE */
}
@media screen and (min-width: 1260px) {
/* YOUR STYLE GOES HERE */
}
/**
* 12.0 Print
* —————————————————————————–
*/
@media print {
/* YOUR STYLE GOES HERE */
}
