Definição e uso

A propriedade scrollWidth retorna toda a largura de um elemento em pixels, incluindo preenchimento, mas não a borda, barra de rolagem ou margem.

Dica: Use a propriedade scrollHeight para retornar a altura inteira de um elemento.

As propriedades scrollWidth e scrollHeight retornam a altura e a largura inteiras de um elemento, incluindo a altura e a largura que não podem ser visualizadas (devido ao estouro).

Dica: Para adicionar barras de rolagem a um elemento, use a propriedade CSS overflow .

Esta propriedade é somente leitura.
