HTML / رموز الرياضيات

طريقة عرض رموز الرياضيات

رموز الرياضيات عبارة عن مجموعة أحرف إن تم وضعها مع بعضها يقوم المتصفح بعرض رمز محدد من الرموز التي نستخدمها في العمليات الحسابية مكانها. هذه الأحرف مهمة جداً فهي تتيح لك إمكانية عرض أي رمز تريد في الصفحة حتى و إن كان غير موجوداً على الكيبورد الذي تستخدمه.
HTML / رموز الرياضيات


الأحرف التي نستخدمها لعرض رموز الرياضيات يمكن وضعها بأسلوب عشري (Decimal) أو بأسلوب سداسي عشري (Hexadecimal)، بالإضافة لأسلوب أصل الإسم (Entity) الذي تم توفيره لبعض الرموز لأنه يعتبر أسهل لك حيث أن الأحرف المستخدمة فيه تكون مكونة من أسماء رموز الرياضيات نفسها.

قاعدة عامة

عند استخدام الأسلوب Entity يجب إضافة & قبل وضع أحرف الرمز.

عند استخدام الأسلوب Decimal يجب إضافة &# قبل وضع أحرف الرمز.

عند استخدام الأسلوب Hexadecimal يجب إضافة &#x قبل وضع أحرف الرمز.

كما أنه يفضّل دائماً وضع فاصلة منقوطة ; بعد كتابة أحرف الرمز و هذا أمر اختياري و لكننا ننصح بفعله.
