## 1 Introduction  
The World Wide Web (WWW) is an advanced platform for instantly sharing information among wide arrays of people [1]. Nowadays, the WWW provides various services (information sharing, communication, serving administrative tasks, etc.) for sectors such as the education, healthcare, and e-commerce sectors. The variety of services provided on the web is unprecedented. This global platform has enormous functionalities and allows of a wide spectrum of devices, highlighting the uniqueness of the web [2]. Although the WWW has the potential to improve global standards, it might not be accessible for people with disabilities if its usage is not designed properly. Therefore, according to our universal accessibility specialist's opinion, the use of the WWW should be designed with concern for all requirements of people with disabilities to keep this platform accessible for them [3]. In 2019, the global COVID-19 pandemic pushed the global scenario into a new dimension. Previously, the WWW was used as a secondary option to provide services such as healthcare, banking, and education. However, in the post-COVID-19 scenario, the WWW has become the primary option for providing these services. For example, people are now comfortable with online consultation with doctors; students prefer to join onlineclasses; and people are obtaining banking services (receiving information, transferring money, checking balances, etc.) online. In this scenario, it is important to maintain the web platform as accessible and barrier-free for all groups of users, especially for people with disabilities. In the post-COVID-19 scenario, hospitals across the world have started to deliver their services through the web platform (e.g., websites), bringing a new dimension to accessing healthcare information and services [4]. Thus, the official web pages of hospitals are becoming the primary source to obtain healthcare resources, such as doctors' information, face-to-face consultation schedules, online consultation appointments, accessing test reports, emergency contact numbers, and patient status. According to the World Health Organization, 15% of the world's population has some sort of disability, which amounts to 1 billion people or one in seven persons in the total population [5]. In addition, according to EU statistics, one in six people who suffer from some disability are active on the Internet [6], while the United Nations reported that more than 10% of people have disabilities in the Asia region [7]. Due to inaccessible web platforms, these significant numbers of people should not be hindered in accessing healthcare information, as obtaining consistent healthcare services is a basic right of everyone. In the Hungarian context, the official census statistics of 2011 show that 500,000 people, or 5% of the total population, experience some type of disability, and this ratio has increased in recent times [8]. Thus, the government of Hungary started several projects, such as \"Supporting people with disabilities\" and \"Human Dignity without Barriers\". The primary objective of these projects was to facilitate access to digital services by introducing a barrier-free environment (i.e., accessible web pages). In addition, Hungary has a significant elderly population (19% of the total population) whose members have one or more disabilities [9]. Ensuring accessibility in both the physical and the digital infrastructure is a crucial factor in assessing the accessible digital healthcare platform and services for elderly people and others who have disabilities. Therefore, in this study, our primary focus is web-page accessibility, especially the accessibility provided by hospital web pages, which are the entry point of healthcare services for people with disabilities. To serve the healthcare needs of so many people, it is compulsory that healthcare web pages are barrier-free. In recent times, information technology serves several facilities to make digital platforms/resources (i.e., web, software, mobile) accessible for people with disabilities [10].
