Following media query is functioning for font-size property of an element but not working for color property of the same element: 
.CSS:
.text-cyan {
    color: #33CCCC;
}
em {
    color: coral;
    font-size: 0.8em
}
@media (max-width: 600px) {
    em {
        color: coral;
        font-size: 0.5em
    }
}  
HTML:
<em class="text-cyan">Start Date: Thursday, September 20, 2018</em>
font-size successfully changes from 0.8em to 0.5em when window size is less than or equal to 600px but not changing color property of the element from #33CCCC to coral. 
Can anyone please help me fix this.
Thanks
