E-books are slowly becoming the type of content without which the widespreading of information in society would be unimaginable. It offers the direct access to books without the need to go to a bookstore or a library phyisically. For this reason, the world has already widely accepted them, and in smaller countries like Croatia, they are gradually making their way onto the market. In order to further enhance the success of this medium, it needs to be developed with higher quality and presented better to the audience. One way to achieve this is by presenting e-books in the form of a responsive website. Its quality is already proven by the variety of periodical and aperiodic content, with more or less amounts of text, being offered in this form. Furthermore, e-books deserve to grow in their own environment, but this requires aligning the visual aesthetics and functionality of the same page. Although e-books in this form still can't replace the popular formats for the display of e-books like PDF and ePub, the responsive web form, together with the previously mentioned two forms, offers a bigger selection of displaying e-books, which attracts more users.
