I want to make a div with background image and at the top there will 3 social media icon like this:
What I wanted:

div#second-footer-container {
background-image: url("https://i.imgur.com/0qRwdSI.png");
width: 100% !important;
background-size: 100% 100%;
background-repeat: no-repeat;
height: 100%;
}
p#socmed-container {
text-align: center;
}
p#socmed-container a {
padding: 0 5px !important;
}
<div id="second-footer-container">
<p id="socmed-container">
<a href="https://www.facebook.com/test/">
<img id="fb-img" width="25" src="https://i.imgur.com/6ye5lwf.png" alt="Facebook" />
</a>
<a href="https://www.instagram.com/test/">
<img id="ig-img" width="25" src="https://i.imgur.com/SEsRzFL.png" alt="Instagram" />
</a>
<a href="https://www.twitter.com/test/">
<img id="twitter-img" width="25" src="https://i.imgur.com/y8o23cc.png" alt="Twitter" />
</a>
</p>
</div>
But the result is not look like what i wanted, my result is the background seems to only follow the main-content height:

I want the width 100% and the height is also 100%, and i want it to be responsive
