Executive PRO theme is using the Genesis Responsive Slider. We need to modify the CSS little bit. I did following changes in the style.css file:
Go to line no 890 and replace the current with this one
.content .genesis_responsive_slider .slide-excerpt { background: none repeat scroll 0 0 rgba(0, 0, 0, 0.7); margin: 0; opacity: 1; padding: 3%; }
Go to line no 913 and replace the current code with this one
.content .genesis_responsive_slider p { color: #ddd; margin: 0; }
Go to line no 954 and replace the current code with this one
.content .genesis_responsive_slider .flex-control-nav { margin: -40px 0 0; padding-left: 0; text-align: center; }
Now go to slider settings page (Genesis->Slider) and setup the width of excerpt content area is 35%. Also you will change the slider position from top to bottom
