Css/fonts/icons issues

Hi, i have an CSS issue with my project GrapesJS and i don't know why... I try to do the tuto and i haven't icons.

Other issue, i can't split the window in 2 columns. I work with the last css and js version. Organisation : assets/js/grapes.js assets/css/grapes.min.css assets/fonts/FontAwesome.otf [...] main-fonts.woff

Code :

<link rel="stylesheet" href="assets/css/grapes.min.css"> <script src="assets/js/grapes.js"></script> <!-- <li><TMPL_VAR NAME=MYURL></li> --> <div id="gjs"></div> <script> var editor = grapesjs.init({ container : '#gjs', components: '<div class="txt-red">Hello world!</div>', style: '.txt-red{color: red}', }); </script>

Thanks !
