How to design the creative logo of UI interface?

Does the question icon refer to the creative icon? My understanding is the icon on the page, I wonder if it is correct.

The most important thing in icon design is to understand the function and then transform it into graphic content. Icons should be highly recognizable, so that users can quickly understand what this function is used for when they see icons. For example, the icon of "bank card" is usually represented by a card.

As far as visual style is concerned, the types of icons in the App applied at this stage can be divided into the following figures:

1, plane area icon; ;

2.2.5D stereoscopic icon; ;

3. Linear icon.

Of course, there are other styles of icon, but they are basically extensions of these three situations.

As far as icons are concerned, the most important thing is to conform to the page style, that is to say, all icon styles need to be unified (I remember that Alipay's icons used to be flat icons, but now they seem to have made some changes and should still be iterated, so the current styles are not very unified).

Finally, recommend a website:

Iconfont (Baidu search Ali gallery can be found, logo is a small skeleton), which contains many icons. Weibo account can be directly logged in, and files in svg format can be downloaded.
