A section separator is used to scale a page area or two neighboring page areas. Section separators are also used to scale table columns and rows.
A section separator is located between two page areas and consists of a bar and in some cases a control point. Section separators can have different manifestations:
- arranged horizontally or vertically,
- continuous or incremental scaling,
- scaling in the range of 0 to 100% (i.e., between hidden and full screen), or with a restricted area,
- scaling of both areas or only one of the two areas (the other area then moves, but remains unchanged in its size).

Operation

---|---|---|---|---|
440 | Use of the keyboard | It must be possible to access, operate and exit the section separator with the keyboard (see Use of the keyboard table, below). Alternatively, it must be possible to scale the area with the keyboard when the focus is in the scalable area. In this case, the use of the keyboard for the section separator must be explained in the application and/or Help option. In addition, it must then be ensured that an area which is hidden by operation of the section separator can also be displayed again. Exception: If the section separator has no relevant function, it does not have to be keyboard-operable. This is the case, for example, if the section separator is used to scale page areas, if all content is fully perceptible in the standard display, and if the scaling does not add any value. | Must | EN 301 549: 9.2.1.1, 11.2.1.1, 9.2.1.2, 11.2.1.2 |
