You’ve put the css inside a media query:
@media only screen and (min-width: 1200px) {
.client-item figure { height: 250px; }
}
.sf-icon-box[class*="sf-icon-box-boxed-"] .sf-icon-box-content-wrap {
background-color: #F4F4F4!important;
}
#logo img, #logo img.retina {
max-width: 100&;
}
Which means it will only apply the css on screens larger than 1200px, which is not what you want. Please take it out of the media query. You need to add a closing bracket to close your media query
