Can a div be easily centered within its parent container?

Question

Can a div be easily centered within its parent container?

In my coding project, I've encountered an issue with centering a #text div inside another #box div. My current attempt at centering it involves CSS code like this:

#box {
  width: 50%;
  #text {position: relative; margin-left: 48%;}
}

While this code does place the #text relatively in the center of the #box, resizing the screen causes the text to shift due to its margin changing size. It's no longer perfectly centered when the screen size changes.

I've heard there are methods involving multiple wrapper divs as a "hack" to solve this issue, but I prefer not to complicate my CSS or HTML too much. Is there a straightforward way to horizontally align a div exactly in the center of its parent?

In my opinion, utilizing flexbox is the most efficient method for centrally aligning child elements both horizontally and vertically. Its compatibility across browsers is impressive.

    height: 300px;
    border: 1px solid red;

If you're aiming for the precise center of a page, no matter the content, try implementing something similar to the code snippet below:

h1 {
  position: absolute;
  left: 50%;
  transform: translateX(-50%);
}

To make it relative to its parent, add the following attribute to the container holding your element:

div.parentOfH1s {
  position: relative;
}
