CSS 属性 inset-block-end 定义了元素的逻辑块末偏移，并根据元素的书写模式、行内方向和文本朝向对应至实体偏移。根据 writing-mode、direction 和 text-orientation 所定义的值，此属性对应于 top、right、bottom 或 left 属性。
尝试一下
writing-mode: horizontal-tb; writing-mode: vertical-rl; writing-mode: horizontal-tb; direction: rtl; writing-mode: vertical-lr; <section id="default-example"> <div class="example-container" id="example-element"> <div id="abspos">I am absolutely positioned with inset-block-end: 20px</div> <p> As much mud in the streets as if the waters had but newly retired from the face of the earth, and it would not be wonderful to meet a Megalosaurus, forty feet long or so, waddling like an elephantine lizard up Holborn Hill. </p> </div> </section> #example-element { border: 0.75em solid; padding: 0.75em; position: relative; width: 100%; min-height: 200px; unicode-bidi: bidi-override; } #abspos { background-color: yellow; color: black; border: 3px solid red; position: absolute; inset-block-end: 20px; inline-size: 140px; min-block-size: 200px; } 语法
css
/* 长度值 */ inset-block-end: 3px; inset-block-end: 2.4em; /* 包含块的宽度或高度的百分比 */ inset-block-end: 10%; /* 关键词值 */ inset-block-end: auto; /* 全局值 */ inset-block-end: inherit; inset-block-end: initial; inset-block-end: revert; inset-block-end: revert-layer; inset-block-end: unset; 取值
inset-block-end 属性的取值与 left 属性相同。
