内联样式反应元素宽度

我正在尝试创建一个具有设置宽度的圆形div。它工作得很好,但一旦我添加的div超过屏幕上适合的div,圆圈的宽度就会被覆盖。父容器具有 overflow: scroll 设置,div可滚动。

这是我的化身组件代码

 const Avatar= ({contact, email, circle, width, margin, fontSize, fontWeight}) => {
  let style = {}

  if (width) {
    style.width = `${width}px` || '32px'
    style.height = `${width}px` || '32px'
    style.margin = `${margin}px` || '4px'
  }

  if (circle) {
    style.borderRadius = `${width/2}px` || '16px'
  }

  let displayName;


  if (contact && contact.avatar) {
    return (
      <img style={style}
        src={contact.avatar}
        title={contact.FN || contact.wyreId || email}
        alt={contact.FN || contact.wyreId || email}
      />
    )
  } ... removed code that sets displayname

  // default display
  style.color = '#fff';
  style.background = 'orange';
  style.lineHeight = style.height;
  style.textAlign = 'center';
  style.fontSize = fontSize;
  style.fontWeight = fontWeight;
  return (
    <div style={style}>
        {
          displayName || '?'
        }
      </div>
  )
}

Here is an image of the components working as intended. Here is an image of the components not working as intended.

当我使用dev工具进行检查时,这是为这两种情况添加到div的样式。 style=width: 32px; height: 32px; margin: 4px; border-radius: 16px; color: rgb(255, 255, 255); background: orange; line-height: 32px; text-align: center; font-size: 16px; font-weight: bold;

知道会出什么问题吗

这里还有在父div上设置的样式以防万一。

.horizontalList {
list-style-type: none;
margin-top: -20px;
margin-left: 2%;
margin-right: 2%;
padding-bottom: 10px;
display: inline-flex;
justify-content: center;
height: 60px;
overflow: scroll;}
