Hypertext Markup Language (HTML) adalah sebuah bahasa markup yang digunakan untuk membuat sebuah halaman website. File HTML pada umumnya dapat dibaca dan diterjemahkan menjadi dalam bentuk tampilan yang lebih manusiawi dengan menggunakan web browser. HTML di tulis dalam berkas format American Standard Code for Information Interchange (ASCII) merupakan suatu standar internasional dalam kode huruf dan simbol seperti Hex dan Unicode tetapi ASCII lebih bersifat universal ASCII disimpan sebagai sandi 8 bit.
Penulisan Tag dan Element pada HTML ditulis seperti berikut ini :
<html>
<head>
<title>HTML Entities</title>
</head>
<body>
<h1>HTML Heading 1</h1>
</body>
</html>
<head>
<title>HTML Entities</title>
</head>
<body>
<h1>HTML Heading 1</h1>
</body>
</html>
Dapat anda lihat source code html diatas menggunakan tanda "<" lebih besar dan tanda ">" lebih kecil untuk mendeklarasikan suatu tag atau suatu element pada HTML. Beberapa web browser versi lama akan mengalami kebingungan dalam menerjemahkan tampilan website apabila terdapat simbol atau tanda-tanda yang mempengaruhi penulisan HTML, untuk penulisan simbol atau suatu tanda yang supaya web browser dapat membedakan yang merupakan format tag HTML dan yang hanya akan ditampilkan secara biasa dapat menggunakan HTML Entities / HTML Entity.
HTML Entities
HTML Entities / HTML Entity atau bisa disebut dengan Entitas HTML adalah karakter dicadangkan dalam bentuk teks dapat dipanggil atau dideklarasikan dengan menggunakan tanda pembuka dan (&), diakhiri dengan tanda titik koma (;) yang memiliki arti atau dapat diterjemahkan oleh web browser menjadi bentuk karakter lain.
Dengan kata lain dapat diartikan bahwa untuk membuat simbol atau untuk membuat suatu karakter tertentu dapat menggunakan Entitas HTML.
