dsSearchAgent mapping IDX includes an admin area where you can modify the colors, but there is no CSS or other layout customization. However, we do include search widgets that can be modified with HTML or CSS. The dsIDXpress IDX plugin is fully customizable with CSS. Nearly every item on each MLS listing page is assigned a class or ID that can be manipulated with CSS. Our IDX MLS plugin usually does a great job adopting the styling of your WordPress theme, but you can make additional changes to all the elements (including listing widgets, IDX modules, and MLS search pages) using CSS.
