Among other disclosed subject matter, a computer-implemented method that includes receiving content items, including text to be displayed on a user's mobile browser. The method also includes determining whether the mobile browser supports floating text columns. The method also includes determining whether at least some of the text should be displayed vertically on the mobile browser, including determining if non-Latin characters are included in the text if the mobile device supports floating text columns. The method also includes rotating text characters of at least some of the text to display vertically in a floating text column, if the text should be displayed vertically.

Displaying vertical content on small display devices

Character style information is stored in an array, in parallel with character information stored within another data structure. The style information array has more memory allocated to it than would be required to store the style information. This surplus memory is employed to form a 'gap' in the array at a location corresponding to the point at which characters are being modified. The gap permits rapid revisions to character style information, while the array storage mechanism permits rapid random access to the style information of any character. Character style information may be mapped to corresponding characters using a run--array mechanism which associates a style with characters through use of an offset which indicates a starting character to which the style applies and a run length which indicates the number of characters to which the style applies. Additionally, the offset may be related to the beginning or to the end of the document, depending upon whether the associated style run falls before or after the memory gap.
