    Qual a diferença entre HTML, CSS e Javascript?

O que é HTML?

HTML é uma sigla para HyperText Markup Language, ou seja é uma linguagem de marcação para hipertexto.
Hipertexto

Hipertexto é texto que não é pleno, ou seja, ele tem dados a mais além do texto.
Um exemplo: qual a diferença entre escrever no Bloco de Notas e no Word?
No word você pode ajustar um tamanho diferente para cada palavra, ajusta fonte, estilos (negrito, italico, sublinhado).
No bloco de notas você possui apenas um texto simples, sem nenhuma estilização.
Então o HTML é uma linguagem para escrever textos com estilização.
