Button font thickness

I can’t seem to change the font thickness of a button using css. Any examples out there?

The following doesn’t work

.interaction-button button {
    font-weight: 100 !important;
}

Hi @Splay ,
Please , use this:

.interaction-button button.webix_button {
    font-weight: 100 ;
}

Please, check the snippet: Code Snippet

Thanks , that’s it :metal:
