We have not implemented a function to change font size and/or zoom level. Those functions rarely work well. Nobody would spend much effort, because modern browsers have their own options for zooming.
The browsers
- Firefox
- Chrome
- Safari
- and even good old Internet Explorer
support zooming. Use the control key combinations
"Ctrl" with "+"
"Ctrl" with "-"
Switch back to original size with
"Ctrl" with "0"
Safari requires using "Cmd" instead of "Ctrl".
If you are using some other browser, please, check the user manual or built-in help.
In case you cann still not use our pages reasonably, feel free to contact our office, phone +49 (0) 511 94 000 948.
