تاثير خرافي بتقنية jquery

السلام عليكم ورحمة

الله وبركاته

نعود لكم بتدوينة جديدة نقدم لكم فيها صفحة الخطئ 404 بتقنية css3 من تطوير عصام ويب

معاينة

طريقة التركيب:

توجه الى القالب ثم تحرير html
ضع الكود التالي في المكان الذي يناسبك ((الصورة))

 <div id="three-container"></div>

ابحث عن <body> وضع فوقه الكود التالي
