To center .card on the page using flexbox, replace the height in the .container and with min-height: 100vh.
There is no need to give the body a width and height 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
Hope am helpful.
Well done for completing this challenge. HAPPY CODING
