margin-inline-start CSS 属性定义元素的逻辑行首外边距,根据元素的书写模式、行内方向和文本朝向映射为实体的外边距。它根据 writing-mode、direction 和 text-orientation 属性的值对应于 margin-top、margin-right、margin-bottom 或 margin-left 属性。
尝试一下
margin-inline-start: 20px;
writing-mode: horizontal-tb;
margin-inline-start: 20px;
writing-mode: vertical-rl;
margin-inline-start: 20%;
writing-mode: horizontal-tb;
direction: rtl;
<section id="default-example">
<div id="container">
<div class="col">One</div>
<div class="col transition-all" id="example-element">Two</div>
<div class="col">Three</div>
</div>
</section>
#container {
width: 300px;
height: 200px;
display: flex;
align-content: flex-start;
justify-content: flex-start;
}
.col {
width: 33.33%;
border: solid #ce7777 10px;
background-color: #2b3a55;
color: white;
flex-shrink: 0;
}
#example-element {
border: solid 10px #ffbf00;
background-color: #2b3a55;
unicode-bidi: bidi-override;
}
语法
css
/* <length> 值 */
margin-inline-start: 10px; /* 绝对长度 */
margin-inline-start: 1em; /* 相对于文字大小 */
margin-inline-start: 5%; /* 相对于最近区块容器的宽度 */
/* 关键词值 */
margin-inline-start: auto;
/* 全局值 */
margin-inline-start: inherit;
margin-inline-start: initial;
margin-inline-start: revert;
margin-inline-start: unset;
这个属性与 margin-block-start、margin-block-end 和 margin-inline-end 属性相关,它们均定义元素的其他边距。
值
margin-inline-start 属性接受与 margin-left 属性相同的值。
