In the first quarter of 2021, extensive changes will be made to the Goobi viewer core. In order to fully support the right-to-left reading direction also in themes, XHTML structures have to be adapted and CSS instructions have to be changed to newer concepts such as CSS Grid and Flexbox. Concepts that are considered obsolete, such as floats, will be removed. Furthermore, individual solutions, for example for absolutely positioned elements or arrows, have to be worked out.
A positive side effect is improved responsiveness for mobile devices.
