QR code using HTML and CSS

Replace <div class="card"> with the main tag to make the content/page accessible. click here for more on web-accessibility and semantic html

Add the alt attribute alt=" " to the img tag and give it a value. The value of the alt attribute is the description of the image. For decorative images like icons, there is no need to give it an alt value, for more on alt attribute Click here.

There is no need to give the body a width. To center .card on the page using flexbox, replace the height in the body with min-height: 100vh.

Give h1 and p text-align: center, the same margin-left, margin-right and margin-top values. Give p a margin bottom value.

For a responsive content,

• Give .card a fixed max-width value and a padding value for all the sides max-width: 320px which is 20rem/em padding:16px which is 1rem/em
• Give the img a max-width of 100% and a border-radius value, the rest are not needed.

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
