css - 字体不变

Question

我一直在尝试为客户在站点上将不同的字体更改为 helvetica。我经历了一遍又一遍，似乎我更改字体的次数越多，似乎每个部分都变成了错误的字体。我不小心将标题栏更改为不同的字体，现在我很困惑。

这是我尝试更改的第一页。这一切都始于唯一不是 helvetica 的东西是它在这里说“博客测试”的地方:http://dolceaquaswim.com/blog/

现在没有任何内容像 helvetica 那样显示。我已经将所有版本的字体上传到服务器，并使用@font 将它们放在 css 中。这是我/主题的 CSS:

Answer 1

Jack 和 rgdesign 的观点都是正确的。你可以看到 @font-face规则用于命名字体或给它一个 ID 并定义它的位置。从它的外观来看，您似乎在尝试编辑已经制作好的东西。问题是我看不到您实际上在哪里引用要更改的位置的字体。对于 CSS 更改并避免使您的 css 文件膨胀，我建议使用像 firebug 这样的工具来查看站点上的 css 并进行可以验证工作的更改。

检查您的网站，您似乎正在为标题定义 Open-Sans。

h1, h2, h3, h4, h5, h6, h1 a, h2 a, h3 a, h4 a, h5 a, h6 a {
    font-family: "Open-Sans";
    font-weight: 700;
    letter-spacing: 1px;
    line-height: 1em;
    word-wrap: break-word;
}

您需要通过将 font-family 定义为 Helvetica Neue 来更改此处的字体，并继续为您要更改的每个部分执行此操作。

h1, h2, h3, h4, h5, h6, h1 a, h2 a, h3 a, h4 a, h5 a, h6 a {
    font-family: 'Helvetica Neue',Helvetica,Arial,sans-serif;
    font-weight: 700;
    letter-spacing: 1px;
    line-height: 1em;
    word-wrap: break-word;
}
