WebflowWebflow allows designers to interact with CSS classes with free drag-and-drop, and the process of defining them without writing any line of code. after the user finishes from design to CSS architecture, they can even publish the built page directly online without having to export the code to other publishing tools. similar to these b2d markets, the reason they are now popular is that they have reduced the technology threshold to a minimum, and that the development of network products is no longer remote to non-technical personnel.
Traditionally, designers have used Photoshop or Illustrator to do this part of their design, as well as some architectural tools such as Twitter's Bootstrap or Zurb Foundation, and the rest are outsourced.
