HTML5 is supported by all modern browsers and thus it is the preferred choice of most developers and companies. It offers a range of tools and functionalities that allow developers to create more dynamic, innovative, and consistent experiences. The code created in HTML5 can be used on multiple platforms and devices, thus it saves time that would otherwise be utilized to develop for each platform and reduces development costs as well. In addition, maintenance is also cheaper, since alterations for one platform can be applied to all platforms. The development process focuses on mobile-friendliness and user experience (UX) contributing to greater user satisfaction and greater engagement and retention. The programming language supports geolocation, application and complex animation storage, among others, through JavaScript and CSS3 API.
