Low emphasis and light-weight button type, such as actions in a table.

Ghost Button#

Used in the dark or colored background.

Call to Action#

Usually appeared alone and intend to used as a command. For example, it is used in the landing page or welcome banner. It could be as wide as its parent container. It is recommend to have just 1 "Call to Action" button in 1 screen.

Placement#

Place buttons in the users' reading pattern for the ease of discovery, such as the "F-Shaped Reading Pattern" and "Z-Shaped Reading Pattern".

How to Decide Button Placement?#

Page/Card/Section presents a subject, where it could be broken into 3 areas:#

  • Header: subject's heading, summary and navigation

  • Body: detailed content

  • Footer: supplementary information or toolbar

Place buttons in different areas could have different meanings.

When to Put Buttons in the Footer?#

  • Body section has collapsed or hidden content, such as it could not show the entire content in one screen;

  • Body section has complex content. For example, it has multiple subgroups and each subgroup has its own actions. Now it is needed to separate "Complete" action from body section to avoid confusion.

In short, footer's purpose is to have a separation from body.

Ordering#

Button Ordering#

Recommend to start from the reading flow, collapsed content should always be on the right.

How to Decide Button Ordering

  • Conversation Flow: place buttons in the order similar to a conversation between computers and users. Ask users the needed actions or your desired actions, then present the risks involved.

  • Navigation Flow: for example, if a button represents going back, should be placed on the left implying it is going to the previous step.

Button Group#

When button group has no space in between, it is easy to confuse it with Toggle Button.

When multiple buttons form a group, align buttons in one line with spaces in between.

Grouping Buttons#

When there are too many buttons on the screen, we could group relevant buttons together and use similar design for that group. If one of the buttons is primary action, we could still use emphasis.

Collapse buttons in the order of importance

If buttons are in the same group, no need to add dividers between them.

Flat display of all the buttons: could separate different groups using space; or use divider to group similar buttons.

Label#

Should use verb

Labels should clearly indicate to users what would happen when buttons got clicked.

  • Should use verb (except dropdown buttons)

  • Should be relevant to the context and be concise.

Infra Design use "OK / Cancel" as default label, but you could still use below methods to customize the label text:

  • Describe the action result.

    Publish, Login, Register.

  • If primary action means negative, stress the consequences.

    Are you sure to delete it? Delete / Cancel
