Spacing

The spacing scale can be applied to margin or padding properties, as well as to both vertical and horizontal edges. The token takes the place of the values normally assigned to margin and padding. The following are all approved ways to syntactically apply Carbon spacing tokens:

Use the spacing scale when building individual components. It includes small increments needed to create appropriate spatial relationships for detail-level designs. This scale is applied and used within all Carbon components.

There are a few other non-token methods that can be used for spacing elements. Each has its own unique use case.

Every part of a UI should be intentional including the empty space between elements. The amount of space between items creates relationships and hierarchy.

Elements in a design that are near each other are seen as being meaningfully related. As more space is added between elements, their perceived relationship weakens.

Patterns created through spacing can also create relationships. Elements arranged in the same spacing pattern are seen as related pieces that have equal weight.

Space can also be used to denote groups of associated information. This creates content sections on a page without having to use lines or other graphical elements as a divider.

Elements that have more spacing around them tend to be perceived as higher in importance than elements that have less space around them. Take this page for instance. The top level headers have more space surrounding them giving them focus and prominence. Then as the headers descend in importance they receive less space, signaling they are subordinate.

Elements that are set close to each other can be easily overlooked. Users may see the grouping but not process each individual item. Therefore, if you have an element or content of high importance on the page, consider giving it extra surrounding space to help it attract focus.

Empty space — also known as white space — is important in design. It can be used to break up sections on a page or to help create focus on certain element(s). White space helps with information processing; too much dense information can be disorienting or overwhelming for a user. Sections of a UI are allowed to be dense, but the whole page should not be crowded; there should be white space to let the user’s eye rest.

There are always exceptions to the rule, but deviating from the spacing scales should be avoided whenever possible.

Yes, in fact it’s encouraged.

Percentages like 50% (1/2) or 33% (1/3) are still acceptable ways to divide a page. Percentages can all still be used to control max and min widths. However, using percentages for padding or margin inside of a component or element should be avoided (ex. padding-right: 10%). The exception to this is if you’re applying it to fit the 5% grid margins.

No, the tokens themselves do not change values based on the screen size. However, it is acceptable at page breakpoints to jump a step(s) on the spacing scale to fit spacing needs (i.e., at 1440 px padding-right: $spacing-05 but at breakpoint 768px padding-right: $spacing-03).
