Replace<div class="container">with the main tag, <p class="title"> with <h1> and <div class="attribution"> with the footer tag to fix the accessibility issues. click here for more on web-accessibility and semantic html

To center .container on the page using flexbox or grid instead of margin, add min-height:100vh; display: flex; align-items: center: justify-content: center; or min-height:100vh; display: grid place-items: center to the body.

To center .container on the page using flexbox:
body{
min-height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}

To center .container on the page using grid:
body{
min-height: 100vh;
display: grid;
place-items: center;
}

For a responsive content, replace the width in container width max-width. max-width:300px. Replace the height in .card with a padding value for all the sides, this will prevent the content from overflowing on smaller screens and its a responsive replacement. padding: 16px.

Give the img a max-width of 100% for a responsive image instead of a width and a border-radius value, the rest are not needed.

Give h1 and p the same font-size of 15px and the same margin-left, margin-right and margin-top values. Give p a margin bottom value.

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
