What is Responsive Web Design: Responsive Web Design allows you to create websites that adapt to the width of the device you are browsing on, allowing you to have a single design for desktop computers, mobile phones and tablets. A very interesting aspect of this new technology is that not only does the design change when the width of the device changes, but the size of the images is also adjusted. Benefits of Responsive Web Design: Cost reduction. Costs are reduced since until today a portal must be made for the Web and another for mobile devices. This causes higher costs of creating and maintaining information. Update efficiency. The site only needs to be updated once and is reflected on all platforms. When we have independent portals for Web and Mobile, the update must be performed twice, which creates the need for a greater amount of resources and the possibility of errors. Improve usability and conversion. This technology contributes to usability and conversion. Studies have been done that show that when the visitor's entire screen is used, conversion increases. Impact on the visitor. Because this technology is new, it generates an impact on the people who see it in action, which will allow the brand to be associated with creativity and innovation.
