How can I customize the background color for a Bootstrap card, specifically filling the entire card including the card text section?
<div class="content">
<div class="card">
<img src="images/qr-code.png" class="card-img" alt="qr-code">
<div class="card-text">
<h3>Improve your front-end skills by building new projects</h3>
<p>Some quick example text to build on the card title and make up the bulk of the card's content.</p>
</div>
</div>
.card {
display: flex;
justify-content: center;
flex-direction: column;
align-items: center;
width: 300px;
height: 490px;
background-color: hsl(0, 0%, 100%);
border-radius: 15px;
text-align: center;
}
.content{
width: 350px;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
margin: 3rem auto 2rem;
padding: 1rem 1rem 1.5rem;

}
