Hi @LuisB,
At present (changing the font size in a matrix question) is not directly possible in KoBoToolbox UI. However this can be done as outlined below:
- Build a matrix question in KoBoToolbox UI (do not forget to select Grid theme under Layout & Settings once you have completed formatting the matrix question).
- Download the xlsform as outline here.
- Make appropriate changes in the xlsform as required. For this you could add various sized headers by prepending # (biggest) to ###### (smallest) to header text.
- An example of how this can be done is shown in the image below:
- After making changes in the xlsform, replace the xlsform with the updated/amended one and then redeploy the survey project. You should now be able to see the changes clearly. As an example please see the images below:
This is an example of the image you see for the default matrix question:
This is an example of the image you see for the amended matrix question:
