Hello,

i want to bring a link in a textblock.  
(like this: here starts the normal textblock an then the Linktext comes and then the normal text goes on.)

i find out, that i can do that with the richtext-element.

but now i have the problem, that i cant bind a formula to the font-size of the richttext-element. but my fontsize depends on the screenwidth and some values in a variable.

how can i bring a formula to the richttextfields font-size?

thank you for help.  
stefan

Ok, i think i must put some classes into the richtext and add some custom style css…

Hi @StefanSan ,

You can control the fonts withini the rich text element by adding an HTML-element above it containing something like this:
