Flexbox has become my favorite way to center an element on a page.

You wrap an item in a div, and you set display: flex and justify-content: center.

<div class="wrapper">
  ...
</div>

.wrapper {
  display: flex;
  justify-content: center;
}

Using Tailwind CSS it’s easier, all you have to do is to add the flex and justify-center classes:

<div class="flex justify-center">
   ...
</div>
