Web service for automated verification of solutions for HTML-layout educational tasks

The task of automated verification of html layout tasks is in demand in the process of learning the basics of web technologies both in educational institutions and during self-training in the relevant areas. The article discusses the features of checking such tasks, which must be taken into account in the case of automated verification. The algorithm of the system for implementation in the form of a web service is given. A feature of the proposed system is the implementation of comparing the layout result with the reference sample by various methods, including using the VGG16 neural network. It is shown that when the similarity threshold is properly set, the image comparison system gives satisfactory results and can be used for automated verification of layout tasks.
