How can I horizontally center an element using CSS?

To horizontally center an element using CSS, you can use the margin property with the auto value.

Here’s an example of how you can horizontally center a div element with a fixed width:

div {
  width: 200px;
  margin: 0 auto;
}

This will center the div element horizontally within its parent element.

You can also use the text-align property to center inline elements, like this:

p {
  text-align: center;
}

This will center all of the inline content within the p element horizontally.

Keep in mind that these methods only work if the element has a fixed width, or if the parent element has a fixed width. If the element or its parent has a flexible width (e.g., width: 100%), the element will stretch to fill the available space.
