Question

我有这种安排。

我有很多类似的图片，我希望地球svg被圆圈包围。

可以在不使用JavaScript来获取尺寸的情况下完成此操作吗？

button {
  background: transparent;
  border: none;
}

    <button type="button">

Answer 1

一个可行的解决方案是将icon-geo-view的viewBox更改为更大的内容，并为svg元素border-radius: 50%加上边框。在这种情况下，svg元素是圆圈。

在您的代码中，viewBox="0 0 26 32"。我以为这可能是错字，但我可能是错的。您的icon-geo-view边界框是正方形，但您的viewBox不是。我认为应该是viewBox="0 0 32 32"。如果要使viewBox更大并在中间保持地球，则可以执行以下操作：-(8/2) -(8/2) (32 + 8) (32 + 8)。

希望对您有帮助。
