嵌套容器内文本顶部垂直对齐问题求助

问题

使用容器布局创建了带有data-type="links-outercontainer"的div，内部嵌套三个带data属性的div：links-lowerleftcontainer、links-lowercentrecontainer、links-lowerrightcontainer。左右容器用于添加描述文本，中间容器作为间隔列。布局整体符合预期，但links-lowerleftcontainer和links-lowerrightcontainer内的文本无法垂直顶对齐。已为这两个容器添加边框以便查看，尝试在这两个容器及上级links-lowercontainer中使用以下样式但无效果：

align-items: center      
justify-content: flex-start     
align-content: flex-start

以下是对应的HTML和CSS代码片段：

解决方向

问题根源在于**links-lowerleftcontainer和links-lowerrightcontainer设置了margin: auto**，在Flex容器中，margin: auto会自动分配剩余空间，导致这两个容器在垂直方向上被居中，从而让内部文本无法顶对齐。

只需做两处修改：

给上级容器links-lowercontainer添加align-items: flex-start，确保子元素在垂直方向（交叉轴）上从顶部开始排列。
移除links-lowerleftcontainer和links-lowerrightcontainer中的margin: auto属性，避免它们被自动居中。

修改后的关键CSS代码如下：

.container[data-type="links-lowercontainer"] {
  container-type: inline-size;
  flex-direction: row;
  padding: 0px 0px 0px 0px;
  display: flex;
  width: 100%;
  margin: auto;
  gap: 0 0;
  border: solid 1px rgba(2, 0, 0, 0.75);
  align-items: flex-start; /* 添加这行，让子元素顶对齐 */
}

.container[data-type="links-lowerleftcontainer"] {
  container-type: inline-size;
  flex-direction: column;
  border: solid 1px rgb(182 255 0);
  padding: 0px 0px 0px 0px;
  display: flex;
  width: 48%;
  /* 移除 margin: auto */
  gap: 0 0;
}

.container[data-type="links-lowerrightcontainer"] {
  container-type: inline-size;
  flex-direction: column;
  border: solid 1px rgb(182 255 0);
  padding: 0px 0px 0px 0px;
  display: flex;
  width: 48%;
  /* 移除 margin: auto */
  gap: 0 0;
}

如果需要进一步确保内部文本完全顶对齐，可以给links-websitedescription添加margin-top: 0，消除浏览器默认给<p>元素添加的顶部外边距。
