Typography


All text in Vanilla uses the Ubuntu typeface , which can be used in your projects.

Vanilla's typographic scale has a base font-size of 1rem.

The value of 1rem

The pixel value of 1rem depends on the browser (in most cases, 16px) and the user's browser settings.

In addition to that, Vanilla multiplies that value by $font-size-ratio--largescreen on resolutions above a certain threshold ($font-size-largescreen). This is done to account for the bigger distance at which larger screens are usually positioned from the viewer.

To disable this behaviour, include the following after you import and include the framework in your scss:

$increase-font-size-on-larger-screens: false;

Text elements in vanilla adhere to a type scale:

  • The base of the scale is the paragraph font-size (1rem)
  • The ratio of the scale is 1.14285714286 (16/14, so both 14 and 16 are members of the scale)

Heading sizes are obtained by taking the ratio to a specified power listed in the table below.

Heading classes

Updated

Heading classes can be added to text elements to give them the same visual appearance as the base h1-h6 heading elements without sacrificing correct heading order and semantics.

In the following example, each heading is actually a <p> element that has been modified to look like a particular heading size.

Deprecated Heading classes with numbers as words (p-heading--one, --two, ...) are deprecated and will be removed in future release v3.0. Please use class names with numbers (p-heading--1, --2, ...) instead.

Sub-headings

Sub-headings visually convey importance beneath a heading, or a line of text that expands on the meaning of the heading immediately before it.

Mixed heading classes

It is also possible to apply heading classes directly to heading elements if that better suits your document style and tree.

Line length

Line length, measured in number of characters per line (CPL), has been shown to affect reading speed and comprehension. While there is little consensus on what the optimal CPL value is, most studies test with values between 45 and 95 characters per line. Wikipedia has a good historical overview and a list of studies on the subject.

The max-width of text elements in Vanilla Framework is limited using the $max-width--default variable, currently set to 40em, or around 90 characters.

Vanilla also includes a utility to unset the max-width where necessary – u-no-max-width:

Overriding or unsetting the max-width is reasonable in certain cases:

  • to avoid an orphan in some fixed, high-profile text, like a promotional banner or notification.
  • when content is wrapped in a text element unintentionally, and fixing the markup is not possible. For example, a CMS or a documentation service might insert <p> after every line break, resulting in <div>'s or <iframe>'s wrapped in <p>'s.

Ordered list

Use an ordered list when the order of the items is important.

Unordered list

Use an unordered list when the order of the items isn't important.

Definition list

Use a definition list when you want to list a group of one or more terms and descriptions.

Blockquotes and citations

Small text

Strong text

Superscripted text

Subscripted text

Abbreviation

Font weights

If you are using the Ubuntu font, it comes in five weights; thin, light, regular, medium, and bold.

Muted text

New

To reduce the prominence of text, use class u-text--muted.

Using a smaller set of Latin font faces

The default Ubuntu fonts are fairly large as they contain glyphs for many languages. If you are building sites in; Afrikaans, Albanian, Catalan, Danish, Dutch, English, German, Icelandic, Italian, Norwegian, Portuguese, Spanish, Swedish or Zulu, you could use the subset of Latin fonts by setting the following variable to true:

$font-use-subset-latin: true;

Enabling Cyrillic, Greek and Latin fonts

Due to the extra weight of loading these fonts they are not imported by default. To enable Cyrillic, Greek and Latin fonts on Ubuntu please set the following font setting to true.

$font-allow-cyrillic-greek-latin: true;

font-display options

The CSS font-display option allows you to set a strategy for what backup font is shown while an external font is loading. This is a very subjective decision; however, if you set the following variable to the option you want, it will add it to the typography for you.

$font-display-option: <auto | block | swap | fallback | optional>;

The default value of the font-display property on all fonts used by Vanilla is set to fallback.

Import

To import just this base element into your project, copy the snippet below and include it in your main Sass file.

@import 'patterns_headings';
