css - 如何在正文中使用一种字体表示正常粗细而另一种字体表示粗体？

Question

我正在尝试将字体“open sans”应用到我的网站。我想对非粗体文本使用“open sans regular”，对粗体文本使用“open sans bold”字体，对斜体文本使用“open sans italic”，最后对“open sans bold italic”使用粗体和斜体的文本。我不想设置类，而只是让它们应用于整个网站。

这是我试过的代码，但它只是应用“open sans italic”，我认为“open sans bold italic”适用于所有内容，即使它不应该是斜体..

@font-face {
    font-family: 'opensans';
    src: url('opensans-regular-webfont.eot');
    src: url('opensans-regular-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-regular-webfont.woff') format('woff'),
         url('opensans-regular-webfont.ttf') format('truetype'),
         url('opensans-regular-webfont.svg#open_sansregular') format('svg');
    font-weight: normal;
    font-style: normal;
}
@font-face {
    font-family: 'opensans';
    src: url('opensans-semibold-webfont.eot');
    src: url('opensans-semibold-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-semibold-webfont.woff') format('woff'),
         url('opensans-semibold-webfont.ttf') format('truetype'),
         url('opensans-semibold-webfont.svg#open_sanssemibold') format('svg');
    font-weight: bold;
}
@font-face {
    font-family: 'opensans';
    src: url('opensans-italic-webfont.eot');
    src: url('opensans-italic-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-italic-webfont.woff') format('woff'),
         url('opensans-italic-webfont.ttf') format('truetype'),
         url('opensans-italic-webfont.svg#open_sansitalic') format('svg');
    font-style: italic, oblique;
}
@font-face {
    font-family: 'opensans';
    src: url('opensans-semibolditalic-webfont.eot');
    src: url('opensans-semibolditalic-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-semibolditalic-webfont.woff') format('woff'),
         url('opensans-semibolditalic-webfont.ttf') format('truetype'),
         url('opensans-semibolditalic-webfont.svg#open_sanssemibold_italic') format('svg');
    font-weight: bold;
    font-style: italic, oblique;
}
body {
font-family:'opensans';
font-size:78%;
}

这里是问题的一个例子，注意所有的字体都是斜体，而它不应该是:http://www.bbmthemes.com/themes/modular/

好的，我想出了我自己的问题。必须有一个非常具体的顺序才能使其正常工作。您需要按以下顺序定义它们:

正常斜体大胆的粗斜体

所以 css 看起来像这样:

@font-face {
    font-family: 'opensans';
    src: url('opensans-regular-webfont.eot');
    src: url('opensans-regular-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-regular-webfont.woff') format('woff'),
         url('opensans-regular-webfont.ttf') format('truetype'),
         url('opensans-regular-webfont.svg#open_sansregular') format('svg');
    font-weight: normal;
    font-style: normal;
}
@font-face {
    font-family: 'opensans';
    src: url('opensans-italic-webfont.eot');
    src: url('opensans-italic-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-italic-webfont.woff') format('woff'),
         url('opensans-italic-webfont.ttf') format('truetype'),
         url('opensans-italic-webfont.svg#open_sansitalic') format('svg');
    font-weight: normal;
    font-style: italic;
}
@font-face {
    font-family: 'opensans';
    src: url('opensans-semibold-webfont.eot');
    src: url('opensans-semibold-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-semibold-webfont.woff') format('woff'),
         url('opensans-semibold-webfont.ttf') format('truetype'),
         url('opensans-semibold-webfont.svg#open_sanssemibold') format('svg');
    font-weight: bold;
    font-style: normal;
}
@font-face {
    font-family: 'opensans';
    src: url('opensans-semibolditalic-webfont.eot');
    src: url('opensans-semibolditalic-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-semibolditalic-webfont.woff') format('woff'),
         url('opensans-semibolditalic-webfont.ttf') format('truetype'),
         url('opensans-semibolditalic-webfont.svg#open_sanssemibold_italic') format('svg');
    font-weight: bold;
    font-style: italic;
}
body {
font-family:'opensans';
font-size:78%;
}
