希望我标记的图像足够容易地描述这个问题。包含图像的红色边框数字没有居中，尽管上面的段落居中。这两个元素都在同一个flexbox容器中。看起来这个图形并不服从它的flexbox父对象。
超文本标记语言：

.stepDescriptionContainer {
  position: relative;
  display: flex;
  flex-direction: column;
  align-items: center;
  border-style: solid;
  border-color: aqua;
  margin: 0px 0px;
  padding: 0px 0px;
}

.stepDescriptionContainer p {
  position: relative;
  margin: 0em 0em;
  padding: 0em 0em;
  text-align: center;
  font-size: 0.9rem;
  --fontOpticalSize: 23; /*Increase with increasing font size 8-144*/
  border-style: solid;
}

.stepImageFigure {
  position: relative;
  display: flex;
  flex-direction: column;
  margin: 0px 0px;
  padding: 0em 0em;
  width: 500px;
  border-style: solid;
  border-color: rgb(255, 17, 0);
}

.stepDescriptionContainer img {
  object-fit: contain;
  width: 100%;
}

<div class="stepDescriptionContainer">
    <div class="triangle"></div>

    <p>We begin with carefully selected kiln-dried hardwoods, ensuring a precise 8% moisture content. This critical measure guarantees the stability and longevity of the final piece. Skilled craftsmen painstakingly inspect each plank; imperfections like deadwood in burls and edges are removed, unveiling nuanced details that enrich the final piece. This stage lays the foundation for the impeccable quality that defines our creations.</p>

    <figure class="stepImageFigure">
        <img src="..\images\Home\WalnutBlueEpoxyResinTable Part1.png" alt="">
    </figure>

</div>

一个重要的点，你看不到的是，CSS上面是在一个媒体查询，其中stepImageFigure从position: absolute到position relative。但我看不出这会引起什么问题。
我试过显示：网格，以及你能想象到的各种对齐和对齐的组合。重新排列HTML但没有成功，交叉检查所有拼写。花了大约5小时试图找到一个答案或替代。
期望图形居中并根据其flexbox父对象进行定位。
谢谢你的帮助
