QR-code "align the element vertically and horizontally in browser"

To center .child on the page using flexbox, add min-height:100vh; display: flex; align-items: center: justify-content: center; to the body

body{
min-height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}

there is no need to give ,.child position: absolute and its properties and a margin value.

Use relative units like rem or em as unit for the padding, margin, width values and preferably rem for the font-size values, instead of using px which is an absolute unit. For more on CSS units Click here and here

Hope am helpful.

Hello there 👋. Congratulations on successfully completing the challenge! 🎉

• I have other recommendations regarding your code that I believe will be of great interest to you.

CSS 🎨:

• Looks like the component has not been centered properly. So let me explain, How you can easily center the component without using margin or padding.

• We don't need to use margin and padding to center the component both horizontally & vertically. Because using margin or padding will not dynamical centers our component at all states

• You already using Flexbox for layout, but you didn't utilized it's full potential. Just add the following rules to properly center the component.

body {
  min-height: 100vh;
  align-items: center;
}

• Now remove these styles, after removing you can able to see the changes

.child {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
}

• Now your component has been properly centered
