Majority of our clients ask for HTML5 coded Rapid eLearning Courses so that the courses are web responsive and work on any mobile devices. With the help of technologies like CSS3, jQuery and AngularJS, the output of the eLearning courses is way higher when compared to other authoring tools. Courses designed are dynamic with more animation and high interactivity as opposed to average eLearning with plain text and images.
While developing HTML5 eLearning, the only challenge we were always faced with was the loading screen. We got this feedback from the learners that the elements on the screen load one after another and sometimes audio is not synced properly. We used a custom preloader in HTML5 and overcame this issue. With this preloader in place, a loading screen indicator is displayed until all the course elements are loaded.
In one of our recent projects, we developed a one-page responsive eLearning course similar to the single-page application (SPA) or website in which the content is loaded only when the learner scrolls the page. In our course, the next screen will be loaded clicking the Next button, but technically all screens are designed in one HTML5 page separated with sections.
This way, by the time learner finishes screen 01, the couple of next screens get loaded in the background. This has really improved the course loading time issue.
Here is reference course snippet for your review using the technique described above.
