Using Inline Font CSS for FontAwesome 5 Unicode Compatibility

I am currently utilizing a library that does not support the font-weight property. Instead, the font style is defined by the font CSS property as detailed here.

After trying to set the font style using the font CSS property with FontAwesome 5, I noticed that it was not working. Could it be that I am doing something incorrectly, or does FontAwesome 5 not support this method of defining the font style?

.calendar::before {
  font-family: "Font Awesome 5 Free";  /* updated font-family */
  font-weight: 400; /* regular style/weight */
  content: "\f133";
}

.calendar2::before {
  font: "400 Font Awesome 5 Free";  /* updated font-family */
  content: "\f133";
}
<link href="https://use.fontawesome.com/releases/v5.7.2/css/all.css" rel="stylesheet"/>
<div class="calendar"></div>

<div class="calendar2"></div>

Answer №1

This information is not directly related to FontAwesome.

When defining the font, it is important to include at least the font-size (specifically a size, not initial, inherit, or unset) and font-family.

According to MDN:

If font is used as a shorthand for multiple font-related properties, then:

  • it must contain values for:
    <font-size>
    <font-family>
  • it can also include values for:
    <font-style>
    <font-variant>
    <font-weight>
    <line-height>

  • font-style, font-variant, and font-weight should come before font-size

  • font-variant can only specify 'normal' and 'small-caps' as values

  • line-height should immediately follow font-size, separated by "/", like so: "16px/3"
  • font-family should be the final specified value.

It is important to note that when optional values are omitted, the default normal will be used instead, overriding any previously set values.

Consider the following approach:

.calendar::before {
  font-family: "Font Awesome 5 Free";  /* updated font-family */
  font-weight: 400; /* regular style/weight */
  content: "\f133";
}

.calendar2::before {
  font: 400 16px "Font Awesome 5 Free";  /* updated font-family */
  content: "\f133";
}
<link href="https://use.fontawesome.com/releases/v5.7.2/css/all.css" rel="stylesheet"/>
<div class="calendar"></div>

<div class="calendar2"></div>

Answer №2

I have identified two mistakes:

  • font requires two mandatory properties: size and family. You have only specified the family property.
  • The text enclosed in double quotes is considered a single value, so adding 400 to it will make it part of the value, rather than a separate value.

Consider using the following code snippet:

.calendar::before {
  font-family: "Font Awesome 5 Free";  /* updated font-family */
  font-weight: 400; /* regular style/weight */
  content: "\f133";
}

.calendar2::before {
  font: 400 1em "Font Awesome 5 Free";  /* updated font-family */
  content: "\f133";
}
<link href="https://use.fontawesome.com/releases/v5.7.2/css/all.css" rel="stylesheet"/>
