I found @font-face is good alternative of sIFR3 but every browser need different extension of font. so implementing is more than sIFR3.
But very good thing is FLASH and Javascript not needed.
Is there any cons to use @font-face in compare to sIFR3? I need compatibility in all A-Grade Browsers.
and
If any font which is freely available as a download on net or if font is purchased and provided by client or font is purchased by my company. in all condition can i use those fonts?
