responsive qrcode using sass

Some recommendations regarding your code that could be of interest to you.

When you download the starter, there is a style-guide.md in the folder. You can use that reference for color, font-size, font-family etc.

• If you want to make the card centered both horizontally and vertically, you'd better add flexbox and min-height: 100vh to the body
• For the background, you can use the recommended color in the body

body {
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
  background-color: hsl(212, 45%, 89%);
}

• If you use max-width, the card will be responsive and you can increase the width a bit
• You'd better update padding to give a gap between the content and the border of the card
• You can add text-align: center to center texts

.main .card {
  /* width: 240px; */
  max-width: 300px;
  border-radius: 10px;
  margin: 0 auto;
  background-color: white;
  /* padding: 10px; */
  padding: 15px;
  text-align: center;
}

• You can add font-size to the .card-title and update it in the card-text

.main .card .card-title {
  font-size: 20px;
}

.main .card .card-text {
  font-weight: 300;
  /* font-size: 12px; */
  font-size: 16px;
}

• You don't need to use .main and .main .block and you can remove them

/* .main {
  position: relative;
  background-color: #DFDBE5;

• Finally, you can remove media queries because the solution will be responsive if you follow the steps above

Hope I am helpful. :)

The instructions to build this card were on directory files you downloaded, if you did want to try again fell free for it. Try to solve this exercise using technologies that you're had control and you'll see how it I'll be easy for you.
