I customized the home template of this photography site to include 4 divs to highlight the 4 major sections of the photographer's portfolio. They are not responsive when sizing the browser or on mobile devices. What do I have to include in order to make them responsive? (media queries min max, not certain)
site: http://jeremy.insctest1.com
one of the divs:
div onclick="window.location='/portfolio/architecture/architecture/';" id="item1" style="width:453px; height:400px; background-image:url('http://jeremy.insctest1.com/wp-content/uploads/2015/02/arch-home.png'); float: left; margin: 0 20px 20px 0;">
div class="item-title" style="width:inherit; position: relative; top:350px; height: 50px; background-image: linear-gradient(to bottom ,rgba(232,232,232,0.8) 0%, rgba(214,214,214,0.8) 100%);">
div class='b' style="
height: 50px;
width: 453px;
display: table-cell;
vertical-align: middle;
text-align: center;">Architecture</div>
