reset csste strong tanımlanmamış olabilir.

ayrıca kullanmış olduğunuz font'ta buna sebebiyet olabilir. Eğer bold desteği yok ise.

@Mhmmd'nin dediği gibi css kodlarınızı paylaşabilirseniz daha iyi yardımcı olabiliriz.
Hocam anarschi den aldığım kodlar ile bir kaç yeri düzelttim ancak bir kaç eksliklik var galiba buyrun
