Primer CSS is a free open-source CSS framework that is built upon a GitHub design system to provide support to the broad spectrum of GitHub websites. It creates the foundation of the basic style elements such as spacing, typography, and color. This systematic method makes sure our patterns are steady and interoperable with every other. Its approach to CSS is influenced by object-oriented CSS principles, functional CSS, and BEM architecture. It is a highly reusable model.
One such very important utility present in Primer CSS is Typography. 

In this article, we will learn about the Typography utility in Primer CSS. 

Typography Utilities 

Typography utilities in Primer CSS are designed so that it works in combination with line-height utilities to make them much more sensible and useful to use. Typography utilities also exist as variables that we can use in components or Custom CSS.
Below given is a table that shows the relationship between scale, the font size on mobile, font size on desktop, and line-height.

Scale Font size: mobile Font size: desktop 1.25 line-height  1.5 line height
00 40px 48px 60 72
0 32px 40px 50 60
1 26px 32px  40 48
2 22px 24px 30 36
3 18px 20px 25 30
4 16px 16px 20 24
5 14px 14px 17.5 21
6 12px 12px 15 18

Typography Utilities:

  • Heading Utilities: We can add the classes from h1 to  h2 to change the font style of any element to the heading font styles.
    This is very useful in situations where we have to change the font style by keeping the markup to be semantically correct. Thus, keeping the hierarchy of the page appropriate.
  • Type Scale Utilities: We can use the Primer CSS type scale classes like f1 to f6 for changing the existing font size of the element. We can also make the inline text lightweight according to our needs by using the classes f0-light to f3-light
  • Line Height Utilities: We can change the line-height of the paragraph using the Primer CSS classes like lh-condensed.This reduces the line height between two lines of the paragraph. We also have responsive line-height class variants like “.lh-sm-condensed” which reduces the line-height of the paragraph for medium screens or larger.
  • Typographic styles: In Primer CSS, we have numerous classes for different typographic styles like bold text, italic, no-wrap, upper case, emphasized, and so on. 
  • Word breaks: In Primer CSS, we have two different classes for word breaks. 
    • wb-break-word: This class when added to any element makes the element break-word if the line width is less than the length of the word after wrapping.
    • wb-break-all: This class when added to any element makes the element break-word irrespective of whether it is shorter or longer than the line width.
  • Text Alignment: In Primer CSS, we can align the text of any element using the different classes like text-left, text-right, and text-center
  • Responsive Text Alignment: In Primer CSS, we can align the text of any element responsively according to the width of the screen in which it is viewed ( large, small, or medium) using the responsive text-align classes like text-sm-center, text-lg-left, and many others. 
  • Removing Bullets: We can remove the bullets from the ordered list by adding the list-style–none class to the <ul> tag of the ordered list in Primer CSS. 

Example 1: In this example, we have created header and text of different sizes by using the different header and typography utility classes.
