Sass

To output all o-normalise styles call the mixin oNormalise:

@include oNormalise();

To include features of o-normalise granularly, pass an $opts map. E.g. to output all styles except for the css helper classes o-normalise-visually-hidden and o-normalise-clearfix:

@include oNormalise($opts: (
	'elements': ('forms', 'images', 'text', 'links'),
	'body': ('font-smoothing', 'box-sizing', 'focus', 'reduce-motion')
));

Options include:

Feature	Description	Values
elements	Element types to apply normalising styles to.	'forms', 'images', 'text', 'links'
body	Features which apply to html, body, main elements and all elements with a :focus state.	'font-smoothing', 'box-sizing', 'focus'
helpers	Classes which may be applied to elements manually.	'clearfix', 'visually-hidden'

Note: if using the "focus" option in your project also include the :focus-visible polyfill. See Focus States.

Other Mixins

• oNormaliseVisuallyHidden - provides styles to visually hide an element while remaining accessible to screen reader.
• oNormaliseClearfix - adds clearfix styles to the element. See this Sitepoint article for more on clearfixes - we use a variation on method 3.
• oNormaliseBoxSizing - adds box-sizing: border-box to the current and all descending elements, see this article by Paul Irish for a full explanation.

Focus States

o-normalise provides default focus states using the :focus-visible pseudo-class. This applies while an element matches the :focus pseudo-class and the user-agent determines that the focus should be specially indicated.

No browser supports :focus-visible right now (31st Jan 2018) but there is a polyfill which roughly mimics the behaviour by adding a class .focus-visible to an element if it should have :focus-visible applied to it. Integrate the polyfill at v4 or v5 with your project to apply these focus styles.

:focus is used as a fallback in core mode.
