Simple QR code page

I suggest following improvement in your CSS code. I just write CSS that should be remove or edit.

.card {   
    width: 300px // set width 300px, after adding 15px left/right padding, the actual size will 
                                300 + 15 + 15 = 330  
    height: 500px; // remove this line
    border: none;  // remove this line
    padding: 15px; add this line for add padding to entire box
}
.qr-code {
    width: 100%; // set width to 100%
    margin: 16px auto 0 auto; // remove this line
}
.title {
    width: 250px; // remove this line
    margin: 0 0 20px 0; // add margin bottom
    text-align: center;  // remove alignment from here and add to the parent div
}
.description {
    width: 250px;  // remove this line
    height: 100px;  // remove this line
    margin: 0; // set margin 0
    text-align: center;   // remove alignment from here and add to the parent div
}

Wrap title and description into a div and add padding to set spacing around the div. i.e.

.xyz {
    text-align: center;
    padding: 20px;
}

Hi! Congrats for finishing challenge. Your solution is very close to the design! Here are some things I think you can improve:

• reset default CSS with *, *::after, *::before {margin:0; padding:0; box-sizing:border-box};
• convert px to relative units (em/rem). Coding in px is usually for magazines/newspapers when you need fix units,
• make variables in :root{} ex for colors here,
• implement BEM naming convention eg .card__qr-code {}. I t will help you in bigger projects and wh you will use SCSS. Happy coding!
