This is a layout design tool that addresses the basic need for responsive web design. This requires a custom responsive layout, a layout that can easily support content in such a way that none of the devices capable of accessing the page have any problems in the content format or the material presented. When you use this prototyping and wire-framing tool, you do not have to worry about generating code. Your focus needs to be on the design. This tool presents you with multiple configurable grid systems for you to choose from. The library of the design elements constantly refreshes and filled in with the new ones.
Features included for customizing layout design lets you add rows and content containers with a simple click. Designer will be able to toggle column spans, stretch rows, or constrain their widths, use sub-grids and container nesting for close layout control.
If necessary, you can tailor layouts around unique content and for special business needs. All it takes is a single drop of the element or a paragraph of content into the intended space. Element properties are highly configurable. You are able to control paddings, margins, floats, font styles, links and everything else. Create a layout in which your unique content looks its best. It is possible to preview the pages at every page width. Preview with actual browser that you are going to support is also possible. This is a very good product.
