Adaptive Layout Template for Effective Web Content Presentation in Large-Screen Contexts

摘要

Despite the fact that average screen size and resolution have dramatically increased, many of today's web sites still do not scale well in larger viewing contexts. The upcoming HTML5 and CSS3 standards propose features that can be used to build more flexible web page layouts, but their potential to accommodate a wider range of display environments is currently relatively unexplored. We examine the proposed standards to identify the most promising features and report on experiments with a number of adaptive layout mechanisms that support the required forms of adaptation to take advantage of greater screen real estates, such as automated scaling of text and media. Special attention is given to the effective use of multi-column layout, a brand new feature for web design that contributes to optimising the space occupied by text, but at the same time stiU poses problems in predominantly continuous vertical-scrolling browsing behaviours. The proposed solutions were integrated in a flexible layout template that was then applied to an existing news web site and tested on users to identify the adaptive features that best support reading comfort and efficiency.
