Baseline 广泛可用 *
margin-inline-start CSS 属性定义了一个元素的逻辑行首外边距，它会根据元素的书写模式、方向性和文本朝向映射到物理外边距。它对应于 writing-mode、direction 和 text-orientation 属性所定义的值，对应着 margin-top、margin-right、margin-bottom 或 margin-left 属性。

语法
css
/* <length> values */
margin-inline-start: 10px; /* An absolute length */
margin-inline-start: 1em; /* relative to the text size */
margin-inline-start: 5%; /* relative to the nearest block container's width */
margin-inline-start: anchor-size(block);
margin-inline-start: calc(anchor-size(--my-anchor width, 30px) / 4);
/* Keyword values */
margin-inline-start: auto;
/* Global values */
margin-inline-start: inherit;
margin-inline-start: initial;
margin-inline-start: revert;
margin-inline-start: revert-layer;
margin-inline-start: unset;
它与定义元素其他外边距的 margin-block-start、margin-block-end 和 margin-inline-end 相关。
值
