I have to insert in a field (admin/structure/types/manage/article/display) a string of classes to get a button from a text but the "Field Formatter Class" field has a character limit so I can't enter the code which I need to get the result. I did some research but couldn't find the solution.

My Class: btn btn-sm btn-primary stpe-outlinebutton test-util-color-primary test-util-border-primary test-util-hover-background-primary test-util-hover-color-white test-util-hover-border-primary

Any help?

Best Regards
