HTML锚点电话标记格式

Question

I have a small question about the anchor tel: tag in HTML. 我对HTML中的锚tel：标签有一个小问题。

Is this valid, or are there any standards on how to write it properly? 这是有效的，还是有关于如何正确编写的标准？

<a href="tel:+358 50 11 22 33"></a>

It has bugged me about the spaces and the prefix, are they allowed? 它使我对空格和前缀感到困惑，是否允许使用它们？

Answer 1

The standards pretty much say that you can't have spaces. 标准几乎说您不能有空格。 So this: 所以这：

<a href="tel:+358 50 11 22 33"></a>

Is valid HTML. 是有效的HTML。
