Sissejuhatus HTML-i sümbolitesse
HTML-is kasutatavad sümbolid on veebiarenduse või rakenduste arendusprotsessi üks olulisemaid osi. HTML-is kasutatakse erinevat tüüpi sümboleid, näiteks matemaatilisi, füüsikalisi, tehnilisi ja valuutasümboleid. Niisuguste sümbolite komplekti kasutamiseks veebilehe arendamisel tuleb kasutada HTML-i olemi nime.
Kui üksuse nime pole, siis saab HTML-i sümboleid kasutada olemi numbriga, mis on koma või kuueteistkümnendsüsteemis. See sisaldab matemaatilisi operaatoreid, nooli, kujundeid, mõnda tehnilist sümbolit, mis pole klaviatuuril saadaval.
