Ever been frustrated by how certain things look great on desktop and not right on your mobile device? Use the following code to targets items on different screen sizes.
 

CSS for Desktop and Mobile

// CSS for Desktop only //
@media only screen and (min-width : 768px) {
   .sqs-block-quote {color: #fecb2f;}
}

// CSS for Mobile only //
@media only screen and (max-width: 768px) {
   .sqs-block-quote {color: #fecb2f;}
}

Replace the CSS value ".sqs-block-quote {color: #fecb2f;}" as needed !!!
