Throughout history, in Croatian children's literature, a teenager has become the main hero of Croatian writers. In this way, the world of young people and their society was discovered, a world that was unknown even to the parents themselves. Every decade, along with every work, introduced us to their world and the changes that young people faced. The changes were based on urban culture and popularity in the world, by following world trends until today. The elements of jeans prose are mentioned as the basic terms of this dissertation, based on studies by Aleksander Flaker, but in the context of Croatian children's literature. The titles created in the 1990s, on which the analysis of the elements is based, are: Maturalac, Krijesnice iz predgrađa, Čuvari amfora, Kakva frka čovječe, Gimnazijske frke, Loša sezona i Knjige lažu! The subjects of the research, or the elements according to Flaker are: adult-non-adult opposition, the world, language gestures, rural-urban opposition, stylization of oral spontaneous speech, frequent implicative expressions. There is an emphasis on belonging to world culture, authority is disparaged, spatial and social evasion as part of the adult-non-adult opposition, and various types of narrators from intelligent, infantile to brutal. It can be said that the life of every young person, especially children, is based on these elements. Thus, through a qualitative method of research, we meet various characters and their life adventures. Young people who feel an aversion to the whole world except what they believe in. The nineties stole many people's childhoods, but also taught them humanity and life. These novels were written in war and post-war times, but still the years of these heroes were the most beautiful with few worries and a lot of optimism. But, each generation brings with it something new.
