## Design Principal
|
|
|
|
- Guide users to achieve the desired actions.
|
|
- Prevent user to make mistakes.
|
|
|
|
## Types
|
|
|
|
### Common Button Types
|
|
|
|
<div>

|
<img alt="buttons" src="https://gw.alipayobjects.com/mdn/rms_08e378/afts/img/A*wsXrT7yQH2MAAAAAAAAAAABkARQnAQ">
|
|
</div>
|
|
|
|
#### ① Default Button
|
|
|
|
Default buttons are used for non-primary actions. If not sure which button type to choose from, the default button is always a safe bet.
|
|
|
|
#### ② Primary Button
|
|
|
|
Emphasize on "complete" or "recommend" action. There is at most one primary button per a button group.
|
|
|
|
#### ③ Text Button
|
|
|
|
Low emphasis and light-weight button type, such as actions in a table.
|
|
|
|
#### ④ Icon Button
|
|
|
|
Icon provides a visual clue.
|
|
|
|
- It could fit more buttons in a small space.
|
|
- Buttons with icon only need to provide Tooltip to indicate the meaning of the button.
|
|
|
|
#### ⑤ Text Button with Icon
|
|
|
|
Provides supplementary meaning to the button.
|
|
|
|

## 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:
|
|
|
|
<ImagePreview>
|
|
<img class="preview-img no-padding" src="https://gw.alipayobjects.com/mdn/rms_08e378/afts/img/A*iVZpRpdN_2AAAAAAAAAAAABkARQnAQ">
|
|
</ImagePreview>
|
|
|
|
- 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?
|
|
|
|
<ImagePreview>

|
<img class="preview-img no-padding" src="https://gw.alipayobjects.com/mdn/rms_08e378/afts/img/A*KGGWQLCBfm0AAAAAAAAAAABkARQnAQ">
|
|
</ImagePreview>
|
|
|
|
- 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

|
|
</ImagePreview>
|
|
|
|
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

<img class="preview-img no-padding bad" src="https://gw.alipayobjects.com/mdn/rms_08e378/afts/img/A*_gU7ToHiZz4AAAAAAAAAAABkARQnAQ" alt="Don't" description="When button group has no space in between, it is easy to confuse it with Toggle Button.">
|
|
</ImagePreview>
|
|
|
|
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.

|
|
</ImagePreview>
|
|
|
|
**Flat display of all the buttons:** could separate different groups using space; or use divider to group similar buttons.

## Label

|
|
</ImagePreview>
|
|
|
|
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.
|
|
|
|
Ant 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
