Can i use your files for web embedding, with @font-face CSS?
If you have bought the licence to use Arista, or if you're using Arista for non commercial use, you can use it with CSS @font-face on your personal website by creating yourself the .eot file with tools like WEFT.
We are, however, NOT supporting @font-face web embedding for various reasons (many expressed here).
As you can read in our licence above our fonts are provided "as it is", so we're not supporting conversions and adaptations to non-standard formats.
