Thank you for the reply, there is an odd discrepancy in the code and/or i am possibly having cache issues.
which one of the below syntax should it have for parentheses around the max-width?
@media{max-width:468px}{
.articles-slideshow .slideshow-inner {
max-height: 400px;
}}
@media(max-width:468px){
.articles-slideshow .slideshow-inner {
max-height: 400px;
}}
