I think it would also be good to add unified global setting size support to el-pagination. What do you think? cc @element-plus/backers

ok!!!

I think it would be better to use useFormSize to get size for el-pagination.

The purpose of this function is to get the size of the previous level rather than just relying on the global, and the use is that if the size is set like 'from', it is actually good to use the local t mentioned above, right?

useFormSize obtains size in the order of props, formItem, form, globalConfig

Why font-size is still 16px? It should be the same as default.

b本地调试出来的确实是14，是否有缓存嫌疑呢

It's weird. I used a new browser. You can see this link.

我也在线上链接复现了该问题，这确实奇怪，我在本地也运行了docs:dev,仍然没有本地复现，我将排查问题

@kooriookami That problem seems to have gone away

[kooriookami]

I think the small size demo can be removed.

[btea]

Maybe we can add a new size effect display here.

Already have.

Oh, I just noticed this.

Thanking Everyone ；

为什么不顺便把 el-config-provider 全局设置也做了呢，现在全局设置了size，Pagination 还是要单独设置size才会生效。
