<P> Since the advent of personal computing, page layout skills have expanded to electronic media as well as print media . E-books, PDF documents, and static web pages mirror paper documents relatively closely, but computers can also add multimedia animation, and interactivity . Page layout for interactive media overlaps with interface design and user experience design; an interactive "page" is better known as a graphical user interface (GUI). </P> <P> Modern web pages are typically produced using HTML for content and general structure, cascading style sheets to control presentation details such as typography and spacing, and JavaScript for interactivity . Since these languages are all text - based, this work can be done in a text editor, or a special HTML editor which may have WYSIWYG features or other aids . Additional technologies such as Macromedia Flash may be used for multimedia content . Web developers are responsible for actually creating a finished document using these technologies, but a separate web designer may be responsible for establishing the layout . A given web designer might be a fluent web developer as well, or may merely be familiar with the general capabilities of the technologies and merely visualize the desired result for the development team . </P> <P> Projected slides used in presentations or entertainment often have similar layout considerations to printed pages . </P> <P> The magic lantern and opaque projector were used during lectures in the 1800s, using printed, typed, photographed, or hand - drawn originals . Two sets of photographic film (one negative and one positive) or one reversal film can be used to create positive images that can be projected with light passing through . Intertitles were used extensively in the earliest motion pictures when sound was not available; they are still used occasionally in addition to the ubiquitous vanity cards and credits . </P>
