The light-speed iteration of the digital world makes products more complex. However, human consciousness and attention resources are limited. Facing this design contradiction, the pursuit of natural interaction will be the consistent direction of Ant Design.
Natural user cognition: According to cognitive psychology, about 80% of external information is obtained through visual channels. The most important visual elements in the interface design, including layout, colors, illustrations, icons, etc., should fully absorb the laws of nature, thereby reducing the user's cognitive cost and bringing authentic and smooth feelings. In some scenarios, opportunely adding other sensory channels such as hearing, touch can create a richer and more natural product experience.
Natural user behavior: In the interaction with the system, the designer should fully understand the relationship between users, system roles, and task objectives, and also contextually organize system functions and services. At the same time, a series of methods such as behavior analysis, artificial intelligence and sensors could be applied to assist users to make effective decisions and reduce extra operations of users, to save users' mental and physical resources and make human-computer interaction more natural.

FAQ

处理异常图片水印

当使用图片水印且图片加载异常时,可以同时添加 content 防止水印失效(自 5.2.3 开始支持)。

<Watermark
height={30}
width={130}
content="Ant Design"
image="https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*lkAoRbywo0oAAAAAAAAAAAAADrJ8AQ/original"
>
<div style={{ height: 500 }} />
</Watermark>

从 5.18.0 版本后,为什么添加了 overflow: hidden 样式?

在之前版本,用户可以通过开发者工具将容器高度设置为 0 来隐藏水印,为了避免这种情况,我们在容器上添加了 overflow: hidden 样式。当容器高度变化时,则内容也一同被隐藏。你可以通过覆盖样式来修改这个行为:

<Watermark style={{ overflow: 'visible' }} />
