Hello Matthias,
Alignment will be easier to handle if you set the first scale’s labels using the .label command and pass it your Text elements: this way, the Text elements will be positioned relative to the radio bullets
Once you have that, it’s a matter of playing with the CSS rules, in particular transform and transform-origin. Here is a suggestion on how to achieve what you’re after (note that I also added one CSS rule to Aesthetics/global_main.css to add spacing between the scales’ options):

Let me know if you have questions
