RADCORE project. I managed to apply the basic rules of the BootStrap 12 column Grid in a fluid way. In addition to the control to apply responsiveness, there are several other visual and operational resources. Accompanies documentation in English. Watch the videos. Since now Thank you all and especially FARSHAD for the incredible work with uniGUI.   Contacts: Flávio Motta mikromundo@gmail.com +55 85 998621405( whatsapp ) https://t.me/projetoradc
