سلام دوستان اینم یه استایل زیبای دیگه که بیش تر شرکتای طراحی از جمله ملی طرح و یزد طرح این رو به کار میبرن البته هنوز این کامل نیس فقط استایل پنجره ها و انیمیشن ایکون هاشه.

خوب برای اعمال این تغییرات کد زیر رو در فایل chat.css موجود در پوشه theme/theme4/css بذارید.

کد:

@font-face {
    font-family: b;
    src: url('../fonts/b.eot'); /* IE9 Compatibility Modes */
    src: url('../fonts/b.eot?') format('eot'),  /* IE6-IE8 */
    url('../fonts/b.woff') format('woff'), /* Modern Browsers */
    url('../fonts/b.ttf')  format('truetype'), /* Safari, Android, iOS */
    url('../fonts/b.svg#svgGraublauweb') format('svg'); /* Legacy iOS */
