How to center a div

Ah, the age-old quest. Developers have died trying. Whole startups were built just to avoid this.

You wanna center a div? You think you're ready?

Fine. Take this dark magic:
.parent {
display: flex;
justify-content: center;
align-items: center;
}

That's it. That’s the answer. That’s all there ever was.

But no, you used margin: auto in 2025 like it’s 2005.
And it didn’t work. And now you're Googling “how to center a div” for the 47th time. Again. Like the rest of us.

Welcome back, hero.
