CSS flexbox and HTML for mobile and desktop

Amazing job my friend, the code looks good and clean but the .container doesn't seem to be perfectly centered like what the design asked for. You can achieve it by removing the margin-top property from .container and copying these lines of code to your CSS file:

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

And also, don't forget to use font-family to make text look better or according to design.

Have a nice day. 👍

You can use the position absolute method to center the component, position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); and also review the margins and padding of image and texts inside the component. you can increase the border radius to match the original design.
