- the re-editing process for example, it is possible to instruct a start of the source document editor, directly edit the structured document displayed at that time, and insert a link to the body content. it can.
- the reading node sequence and the structured document are read from the storage area 30 into the source document editor, and the reading node is read.
- entering a character string that has a link to the body content for the column "Do you want to stop reading below and jump to the body content?", Enter a link at the corresponding structured document position You can also.
- step S60 the edited structured document is displayed on the screen, a graphic display of the arrival time is executed, and the above-described processing is performed until a command input indicating that the creator is satisfied with the accessibility is received in step S62.
- the signals satisfying the accessibility include, for example, an edit end command (E) and a storage command (S) in the present invention, and a command that provides an equivalent function corresponding to these commands.
- step S64 the edited DHTML document is stored in a database or the like to enable provision of a non-visual access web page with improved user accessibility.
- step S54 when the creator clicks on the “correction simulation” menu and makes an input, the conversion determination means causes the correction menu to be displayed. At this time, if the creator selects "Time to text", a pop-up menu will be displayed to select the display format from "Gradation of display color”. In addition, the creator If you select "Gradient of color", a menu item for inputting "Selection of color” is displayed, and a display format determination command is sent to the conversion determination means.
- FIG. 8 shows that a menu for selecting or determining a display format is displayed in accordance with the processing of steps S52 and S54.
