Qr code component challenge using basic html and css

Hi i liked your UI some much. It has a little bit different positioning than the original one but yours look better i think. For the code, i recommend you to look at semantic HTML codes. You should wrap the app inside <main> tag for making it semantic instead of using too many <div> tags it will make your code look more professional.

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

HTML

• In order to center the card correctly, you'd better remove <div class="container-fluid"> from html.

CSS

• Then, you'd better add flexbox and min-height: 100vh to the body to center the card vertically and horizontally

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

• If you use flexbox in the body, you don't need to use margin in the .main-div to center the card
• If you use max-width instead of width, the card will be responsive
• You'd better give padding to give a gap between the content and the border of the card

.main-div {
  /* width: 275px; */
  max-width: 275px;
  /* margin: 9% auto; */
  padding: 10px;
}

• In addition to that above, in order to make the card responsive and the image positioned completely on the card, you'd better add width: 100% and display: block for the img in this way:

img {
  /* width: 250px; */
  /* height: 250px; */
  border-radius: 5%;
  /* margin-bottom: 5%; */
  width: 100%;
  display: block;
}

• You don't need to use margin and width for p and you can remove them

p {
  /* width: 95%; */
  /* margin: 0 auto; */
}

• Finally, you'd better remove .section-img to avoid the repetition if you want

/* 
.section-img {
  padding-top: 12px;
} 
*/

Hope I am helpful. :)
