Layout Changes

For the design of our website we use from now on the CSS framework Bootstrap. For this purpose various adjustments on the page layout will be made, starting today and in the coming days. Please understand, there can be temporary changeover problems. We work on it...
Please, if a function does not work as usual, load the relevant page in the browser again by pressing the key combination Strg + F5.
