I have a SharePoint list. When a user inserts a new item in the list an dialog screen appears.
On the dialog screen is a text box where the user can insert text and when the user clicks on the save-button the text from the textbox will be inserted in column "Description".
By default font of the textbox is "Calibri". But what I would like is when the user closes the dialog by clicking on the Save button that in the field "Description" the font changes to "Segoe UI".
I guess I need some JSON-code for the column Description.
Who can help me? Thank you in advanced.
