3. کد جاوا اسکریپت خود را تولید کنید (تمام سرویس دهندگان این امکان را پیاده سازی کرده اند).

4. قطعه کد جاوا اسکریپت تولید شده را، در قسمت <head> فایل (Layout.cshtml (Razor_ یا (Site.Master (ASPX کپی کنید.

5. CSS Selector‌‌های لازم برای فونت مورد نظر را تولید کنید.

6. کد css تولید شده را در فایل Site.css کپی کنید. در مثال جاری فونت کل اپلیکیشن را تغییر می‌دهیم. برای اینکار، خانواده فونت "bistro-script-web" را به تگ body اضافه می‌کنیم.

نکته: فونت cursive بعنوان fallback تعریف شده. یعنی در صورتی که بارگذاری و رندر فونت مورد نظر با خطا مواجه شد، از این فونت استفاده می‌شود. بهتر است فونت‌های fallback به مقادیری تنظیم کنید که در اکثر پلتفرم‌ها وجود دارند.

همین! حالا می‌توانیم تغییرات اعمال شده را مشاهده کنیم. بصورت پیش فرض قالب پروژه‌ها از فونت "Segoe UI" استفاده می‌کنند، که خروجی زیر را رندر می‌کند.

استفاده از فونت جدید "Bistro Script Web" وب سایت را مانند تصویر زیر رندر خواهد کرد.

همانطور که می‌بینید استفاده از فونت‌های وب بسیار ساده است. اما بهتر است از اینگونه فونت‌ها برای کل سایت استفاده نشود و تنها روی المنت‌های خاصی مانند سر تیتر‌ها (h1,h2,etc) اعمال شوند.
