Abstract

The object of the present invention is to render markup documents within the limits of resolutions smaller than the resolutions for which the documents were originally designed, in most cases without introducing horizontal scrolling, while keeping the original fonts, colors, design, and style. The object is achieved by finding and selecting only elements that are too big, shrinking them individually, and disallowing certain elements to grow table cells under specific circumstances.

Claims

1. Method for modifying and presenting content in a document (630), written in a markup language for presenting on a display (615) with smaller resolution than the document (630) is designed for, by means of a browser (650), comprising the steps of:

applying separate functions (655), which functions (655) are coded into the browser (650) and which functions (655) cooperate, overriding markup and style where necessary and,

presenting the modified document on the display (680).

2. Method according to claim 1, where one function is resizing table cells by calculating the minimum width of cells.

3. Method according to claim 1, where one function is repositioning a page element outside of the width of the display (680).

4. Method according to claim 1, where one function is resizing non-wrapping content.

5. Method according to claim 1, where one function is wrapping text.

6. Method according to claim 2, where calculating of the minimum width of table cells is performed by:

overriding the original width by setting the width to auto, and

excluding the width of replaced content contained in table cells when performing the calculation.

7. Method according to claim 3, where the repositioning of a page element comprises the following steps:

identifying the page element,

analyzing the element with regard to size and functionality,

approving or disapproving the element for repositioning,

repositioning the element if approved, either based on where it occurs in the document (630), or at the top or bottom of the modified content.

8. Method according to claim 2 and 4, where the resizing of non-wrapping content is performed by shrinking or squeezing all elements to fit inside the new width of the containing table cell.

9. Method according to claim 4, where the resizing of non-wrapping content is performed on objects contained both inside and outside table cells.

10. Method according to claim 5, where the wrapping of text is done in the middle of a word if normal wrapping fails to avoid overflow or horizontal scrolling.

11. Method according to claim 7, where the page element is among all types of elements that can be included in the markup language.

12. Electronic device (640) comprising a processing unit (670), a memory (660) and a display (680) for modifying and presenting a document (630), written in a markup language for presenting on the display (680) with smaller resolution than the document (630) is designed for, by means of a browser (650) loaded in the memory (660) wherein said processing unit (670) is arranged for performing the following steps:

applying separate functions (655), which functions (655) are coded into the browser (650) and which functions (655) cooperate, overriding markup and style where necessary and,

displaying on the display (680), a document (685) comprising redefined content.

13. A Web browser (650) adapted for modifying and presenting content in a document (630), written in a markup language for presenting on a display (615) with smaller resolution than the document (630) is designed for, comprising computer program modules for:

applying separate functions (655), which functions (655) are coded into the browser and which functions cooperate, overriding markup and style where necessary and,

presenting the redefined content in a document (685) on the display (680).
