在像Facebook这样的按钮中设置头像图像的样式？

<div class="button-container">
  <img src="avatar.jpg" alt="Avatar" class="avatar">
  <span class="button-text">按钮文本</span>
</div>

.button-container {
  display: inline-block;
  border: 1px solid #ccc;
  border-radius: 4px;
  padding: 10px;
}

.avatar {
  width: 50px;
  height: 50px;
  border-radius: 50%;
}

.button-text {
  margin-left: 10px;
}

<button class="facebook-button">
  <div class="button-container">
    <img src="avatar.jpg" alt="Avatar" class="avatar">
    <span class="button-text">按钮文本</span>
  </div>
</button>
