A propriedade CSS block-size define o tamanho horizontal ou vertical de um elemento bloco. Corresponde à propriedade width ou height, dependendo do valor do writing-mode.

Experimente

block-size: 150px; writing-mode: horizontal-tb;

block-size: 150px; writing-mode: vertical-rl;

block-size: auto; writing-mode: horizontal-tb;

block-size: auto; writing-mode: vertical-lr;

<section class="default-example" id="default-example"> <div class="transition-all" id="example-element"> This is a box where you can change the block-size. </div> </section>

#example-element { display: flex; flex-direction: column; background-color: #5b6dcd; justify-content: center; color: #ffffff; }

Sintaxe

css

/* valores <length> */ block-size: 300px; block-size: 25em; /* valores <percentage> */ block-size: 75%; /* valores de Keyword */ block-size: 25em border-box; block-size: 75% content-box; block-size: max-content; block-size: min-content; block-size: available; block-size: fit-content; block-size: auto; /* valores globais */ block-size: inherit; block-size: initial; block-size: unset;

Se o modo de escrita está orientado verticalmente, o valor do block-size refere-se à largura do elemento; senão, refere-se à altura do elemento. Uma propriedade relacionada é inline-size, que define as outras dimensões do elemento.

A propriedade block-size leva os mesmos valores que as propriedades width e height.
