计算机科学中最困难的问题:居中对齐

Translations: Russian

翻译:俄语

This is my claim: we, as a civilization, forgot how to center things.

这是我的观点:作为一个文明,我们忘记了如何居中事物。

I mean, we know how to do it. It has never been simpler:

我的意思是,我们知道如何做到。这从未如此简单:

display: flex;
justify-content: center; /* Horizontal centering */
align-items: center; /* Vertical centering */

(don’t ask why you need to remember four words instead of just horizontal/vertical, it’s still better than before)

(不要问为什么你需要记住四个单词而不是只有水平/垂直,这仍然比以前好

Or you can use grids if you want:

或者你也可以使用网格:

display: grid;
justify-items: center; /* Horizontal centering */
align-items: center; /* Vertical centering */

(also don’t ask why justify-content became justify-items)

(也不要问为什么justify-content变成了justify-items

If you feel like school today, we can deduce it from the first principles:

如果你今天感觉像上学,我们可以从第一原理推导出来:

Hey, even ChatGPT knows how to center things:

嘿,连 ChatGPT 都知道如何居中:

Okay, maybe not right away, but eventually it gets there.

好吧,也许不是立刻,但最终会实现。

What I’m saying is: everybody knows how to center things. It’s trivial. And if you are lost, the knowledge is right there.

我要说的是:每个人都知道如何居中。这是微不足道的。如果你迷失了方向,知识就在那里。

Yet, when we look at actual applications, we see that these methods are not used. We see this:

然而,当我们看实际应用时,我们发现这些方法并没有被使用。我们看到这样的情况:

or this:

或者是这样:

or even this:

甚至是这样:

So something is clearly getting lost between know-how and applying that knowledge.

所以显然在知识和应用知识之间有些东西被忽略了。

In theory, there’s no difference between theory and practice. Unfortunately, we live in practice.

理论上,理论和实践之间没有区别。不幸的是,我们生活在实践中。

So what’s happening? Let’s find out.

那么,发生了什么?让我们找出来。

Fonts
