Abstract
Having an online presence is essential for any company regardless of its size and type of business. Users are currently striving to interact with companies through the web, regardless of their access device. In this sense, responsive web design emerged as a very useful technique that allows the dynamic adaptation of the design regardless of the size and resolution of the access device. Despite the unequivocal advantages associated with this technique, there are also limitations which turn this approach not feasible or advisable for all projects. This study, through the realization of five case studies, seeks to identify the main limitations of responsive design and responsive design frameworks. Additionally, this study suggests further development models that may be more effective in the dynamic adaptation of the design and contents according to the features of the access device, such as the adoption of adaptive design, use of native apps, and hybrid models.

Abstract
Nonprofit organizations are constantly challenged to find new ways of finding new donors and sources of funding for their solidarity actions. The traumatic events that occurred in the summer of 2017 in Portugal that caused more than 100 deaths consumed by the fires caused these organizations to have difficulties in coordinating the whole wave of solidarity generated in the community. In this sense, this study has developed a technological platform based exclusively on free technologies that allowed these entities to receive donations and manage this whole process. The application developed enables the reception of anonymous donations and monitoring the status of each donation. Furthermore, several requirements in terms of compatibility with mobile devices, usability, security, and privacy were implemented in the platform.
