HTML 验证产生错误

Question

我正在使用 google 字体，它会为以下 link

生成以下错误

<link href="http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic|Montserrat:700|Merriweather:400italic|Roboto+Condensed|Source+Sans+Pro|Droid+Serif|Open+Sans+Condensed|Oswald|Molengo|PT Sans|Droid Sans')" rel="stylesheet" />

错误信息

Line 35, Column 289: Bad value for attribute href on element link: Illegal character in query: not a URL code point.
…if|Open+Sans+Condensed|Oswald|Molengo|PT Sans|Droid Sans')" rel="stylesheet" />
Syntax of URL: Any URL. For example: /hello, #canvas, or http://example.org/. Characters should be represented in NFC and spaces should be escaped as %20.

样本HTML

<html>
<head>

    <title>Title</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1, maximum-scale=1" />
<link href="http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic|Montserrat:700|Merriweather:400italic|Roboto+Condensed|Source+Sans+Pro|Droid+Serif|Open+Sans+Condensed|Oswald|Molengo|PT+Sans|Droid+Sans')" rel="stylesheet" />
</head>
<body>
</body>
</html>

更新

这会产生错误

 <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Roboto%20Condensed|Source%20Sans%20Pro" />

这有效

 <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Lato"  />

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Roboto%20Condensed" />

当我添加 | 来添加多种字体时，它会产生错误，所以我应该使用多个 <link> 标签来添加字体还是？

对此感到困惑如下 links 是由 Google 网站上使用的字体字体生成的

https://www.google.com/fonts#UsePlace:use/Collection:Open+Sans|Roboto:400,700,400italic|Roboto+Condensed:400,300|Lato

Answer 1

字符串末尾有一个space

PT Sans|Droid Sans')"

应转义为：

PT%20Sans|Droid%20Sans')"

Answer 2

您的示例代码使用 JAVASCRIPT NOTATION LINK 和 IMPORT 可能无助于消除 VALIDATION 错误 - 所以请尝试使用 JAVASCRIPT 符号，它运行良好，没有任何错误。

<!DOCTYPE html>
<html>
<head>

    <title>Title</title>
    <meta charset="utf-8" />
<script type="text/javascript">
WebFontConfig = {google: { families: [ Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic|Montserrat:700|Merriweather:400italic|Roboto+Condensed|Source+Sans+Pro|Droid+Serif|Open+Sans+Condensed|Oswald|Molengo|PT+Sans|Droid+Sans ] }};
(function() {
    var wf = document.createElement('script');
    wf.src = ('https:' == document.location.protocol ? 'https' : 'http') +
      '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
    wf.type = 'text/javascript';
    wf.async = 'true';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(wf, s);
  })();
</script>
</head>
<body>
</body>
</html>

您需要将 & 符号替换为 &

<!DOCTYPE html>
<html>
<head>

    <title>Title</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1, maximum-scale=1" />
<link href='http://fonts.googleapis.com/css?family=Open+Sans&amp;subset=latin,cyrillic-ext,greek-ext,greek,vietnamese,latin-ext,cyrillic' rel='stylesheet' type='text/css'>
</head>
<body>
</body>
</html>

您可以使用 JAVASCRIPT 符号来包含来自 google

的字体

<!DOCTYPE html>
<html>
<head>

    <title>Title</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1, maximum-scale=1" />
<script type="text/javascript">
  WebFontConfig = {
    google: { families: [ 'Open+Sans::cyrillic-ext,latin,greek-ext,greek,vietnamese,latin-ext,cyrillic' ] }
  };
  (function() {
    var wf = document.createElement('script');
    wf.src = ('https:' == document.location.protocol ? 'https' : 'http') +
      '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
    wf.type = 'text/javascript';
    wf.async = 'true';
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(wf, s);
  })(); </script>
</head>
<body>
</body>
</html>

还有一些建议

始终在 HTML 页面顶部包含文档类型
尝试使用 IMPORT 和 JAVASCRIPT 替代方法来包含字体。
请使用您自己的 google 字体 - 以避免拼写错误我尝试使用来自 google.

Answer 3

字符 | 是 not allowed in the query component（也不是 URI 中的任何其他地方）。它必须用 %7C.

进行百分比编码

所以

http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic|Montserrat:700|Merriweather:400italic|Roboto+Condensed|Source+Sans+Pro|Droid+Serif|Open+Sans+Condensed|Oswald|Molengo|PT+Sans|Droid+Sans')

应该是这个 URI

http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic%7CMontserrat:700%7CMerriweather:400italic%7CRoboto+Condensed%7CSource+Sans+Pro%7CDroid+Serif%7COpen+Sans+Condensed%7COswald%7CMolengo%7CPT+Sans%7CDroid+Sans')
