For many years, it was taught in the traditional way, for which chalk, a blackboard, a map, and sometimes an overhead projector were used most often. However, the world is advancing technologically, so the turn has come for the digitization of education. In 2015, the program "e-Schools: Complete informatization of school business processes and teaching processes for the purpose of creating digitally mature schools for the 21st century" began, which started the digitization of the learning and teaching process. Therefore, teachers had to acquire information and communication competences (ICT). Digital educational contents are all contents used in the educational process, which are in digital form. They are intended for teachers to present teaching content in a more interactive way and to be able to show students phenomena and processes that they can not see in the environment. They are intended for students to use them for independent work. Digital educational content is available to teachers on various websites, book publishers have digitized materials and they can also create them independently using various tools. During the COVID-19 pandemic, the entire school system was transferred to an online format, i.e. distance learning. That's when teachers' ICT competencies came to the fore, which could greatly facilitate distance learning because they had to use digital platforms, tools and content to convey new knowledge to students. A research was conducted, the aim of which was to examine the opinions and attitudes of classroom teachers regarding the application of digital educational content in the teaching of the Croatian language, Mathematics, and Nature and society. 15 participants took part. The technique of focus group, i.e. in-depth interview, was used. Various positive and negative attitudes and thoughts are listed. Participants use digital content in all stages of the lesson. Some use them often, but moderation is also advised when using digital content. Certain participants call for greater involvement in getting to know and preparing the digital content itself, as it is of great help in teaching.
