为什么 HTML 要求多个空格在浏览器中显示为单个空格? [英] Why does HTML require that multiple spaces show up as a single space in the browser?
问题描述
我早就认识到 HTML 文件中的任何一组空格都只会显示为一个空格.例如，这个:
I have long recognized that any set of whitespace in an HTML file will only be displayed as a single space. For instance, this:
<p>Hello. Hello. Hello. Hello. Hello.</p>
显示为:
你好.你好.你好.你好.你好.
Hello. Hello. Hello. Hello. Hello.
这很好，好像您需要多个预先格式化的文本空格，您可以使用 <pre>标签.但原因是什么?更准确地说，为什么在 HTML 规范中会出现这种情况?
This is perfectly fine, as if you need multiple spaces of pre-formatted text you can just use the <pre> tag. But what is the reason? More precisely, why is this in the specification for HTML?
推荐答案
HTML 中的空格是压缩的，因为 HTML 的格式化方式和呈现方式之间存在区别.考虑这样一个页面:
Spaces are compacted in HTML because there's a distinction between how HTML is formatted and how it should be rendered. Consider a page like this:
<html>
<body>
<a href="mylink">A link</a>
</body>
</html>
例如，如果 HTML 使用空格缩进，则链接前面会带有多个空格.
If the HTML was indented using spaces for example, the link would be preceded by several spaces.
