img { width: 100px; height: auto; margin-left: 10px; border: none; }

好的，以下是针对这段 CSS 代码的注释信息：

img {                       // 选择所有 <img> 元素
   width: 100px;            // 设置宽度为 100 像素
   height: auto;            // 设置高度自动适应
   margin-left: 10px;       // 设置左侧外边距为 10 像素
   border: none;            // 取消图片边框
}

在你的 CSS 中，第一种方法的居中方式使用了 `margin: auto;`，这个属性应该是可以实现水平居中的，但是你可能需要检查一下你的HTML代码和CSS代码是否有其他的影响元素居中的属性。

可以尝试在需要居中的元素上添加 `display: block;` 属性，或者使用 `text-align: center;` 实现水平居中。如果还是无法解决问题，可以提供一下你的 HTML 代码，我可以帮你分析一下。
