    Animatsiyani boshlash uchun elementning usuli deyiladi BeginAnimation(). Bu usul animatsiya
    qilinadigan bog'liqlik xususiyati va animatsiya ob'ektining o'ziga o'tadi.
    Bunday holda, tugmaning kengligi joriy qiymatdan 150 pikselgacha o'zgaradi. Va bu o'zgarish 3
    soniya davom etadi.
    Agar animatsiya takrorlanishini istasak, RepeatBehavior xususiyatidan foydalanishimiz mumkin:
    Bunday holda, animatsiya ikki marta takrorlanadi. Biz takrorlash vaqtini ham belgilashimiz
    mumkin:
    Bu erda takrorlash vaqti 7 soniya. Animatsiya 3 soniya davom etadi, ya'ni 7/3 takrorlash bo'ladi:
    ikkita to'liq takrorlash va ikkinchi holatda kenglik faqat kerakli kenglikning uchdan bir qismiga
    oshadi.
    Xususiyatning teskari yo'nalishda silliq o'zgarishini o'rnatish uchun AutoReverse xususiyatini
    qo'llang:
    Tugallangan tadbir
    Animatsiya tugagach, tugallangan hodisa yaratiladi, biz uni boshqarishimiz mumkin:
