如何为同一字体添加多个字体文件？

Question

我正在查看@ font-face CSS规则的MDC页面,但我没有得到一件事.我有单独的文件粗体,斜体和粗体+斜体.如何将所有三个文件嵌入一个@font-face规则中？例如,如果我有:

@font-face {
    font-family: "DejaVu Sans";
    src: url("./fonts/DejaVuSans.ttf") format("ttf");
}
strong {
    font-family: "DejaVu Sans";
    font-weight: bold;
}

浏览器将不知道哪个字体用于粗体(因为该文件是DejaVuSansBold.ttf),因此它将默认为我可能不想要的东西.如何告诉浏览器我对某种字体的所有不同变体？

Answer 1

解决方案似乎是添加多个@font-face规则,例如:

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}

顺便说一句,谷歌Chrome似乎不知道这个format("ttf")论点,所以你可能想跳过它.

(这个答案对于CSS 2规范是正确的.CSS3只允许一个字体样式而不是逗号分隔列表.)

Answer 2

从CSS3开始,规范发生了变化,只允许一个font-style.以逗号分隔的列表(根据CSS2)将被视为它normal并覆盖任何早期(默认)条目.这将使以这种方式定义的字体永久显示为斜体.

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: oblique;
}

在大多数情况下,斜体可能就足够了,如果你注意定义你将使用哪个并坚持下去,就不需要倾斜规则.

Answer 3

为了让字体变化正常工作,我不得不颠倒CSS中@ font-face的顺序.

@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}   
@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono-Bold.ttf");
    font-weight: bold;
}
 @font-face {
    font-family: "DejaVuMono";
    src: url("styles/DejaVuSansMono.ttf");
}

Answer 4

如果您使用的是Google字体,我建议如下.

如果您希望从本地主机或服务器运行字体,则需要下载文件.

不要在下载链接中下载ttf软件包,而是使用它们提供的实时链接,例如:

http://fonts.googleapis.com/css?family=Source+Sans+Pro:300,400,600,300italic,400italic,600italic

将URL粘贴到浏览器中,您应该获得类似于第一个答案的字体 - 面部声明.

打开提供的URL,下载并重命名文件.

将更新后的font-face声明与相对路径粘贴到CSS中的woff文件中,就完成了.

Answer 5

如今,二○一七年十二月一十七日.我没有在规范中找到任何关于字体属性顺序的必要性的描述.而我在chrome中的测试始终无论订单如何都能正常工作.

@font-face {
  font-family: 'Font Awesome 5 Free';
  font-weight: 900;
  src: url('#{$fa-font-path}/fa-solid-900.eot');
  src: url('#{$fa-font-path}/fa-solid-900.eot?#iefix') format('embedded-opentype'),
  url('#{$fa-font-path}/fa-solid-900.woff2') format('woff2'),
  url('#{$fa-font-path}/fa-solid-900.woff') format('woff'),
  url('#{$fa-font-path}/fa-solid-900.ttf') format('truetype'),
  url('#{$fa-font-path}/fa-solid-900.svg#fontawesome') format('svg');
}

@font-face {
  font-family: 'Font Awesome 5 Free';
  font-weight: 400;
  src: url('#{$fa-font-path}/fa-regular-400.eot');
  src: url('#{$fa-font-path}/fa-regular-400.eot?#iefix') format('embedded-opentype'),
  url('#{$fa-font-path}/fa-regular-400.woff2') format('woff2'),
  url('#{$fa-font-path}/fa-regular-400.woff') format('woff'),
  url('#{$fa-font-path}/fa-regular-400.ttf') format('truetype'),
  url('#{$fa-font-path}/fa-regular-400.svg#fontawesome') format('svg');
}
