How can I use Bootstrap4 and CSS3 to position picture 4 and 5 under picture 2 and 3 within a grid layout?
<main>
<div class="container-fluid">
<div class="row">
<h1 class="col-12">Anonymous</h1>
</div>
<div class="row">
<!-- pic 1 -->
<div class="col-6 card border-0">
<img id="img-anonymous" src="images/home picture/_118375100_gettyimages-1304610824.jpg" alt="Anonymous Hackers"/>
<div class="card-img-overlay">
<p>Anonymous Hackers:</p>
</div>
</div>
<!-- pic 2 -->
<div class="col-3 card border-0">
<img id="img-anonymous" src="images/home picture/_118809405_index.jpg" alt="Anonymous Hackers"/>
<div class="card-img-overlay">
<p>Anonymous Hackers:</p>
</div>
</div>
<!-- pic 3 -->
<div class="col-3 card border-0">
<img id="img-anonymous" src="images/home picture/_118809064_tv067645357.jpg" alt="Anonymous Hackers"/>
<div class="card-img-overlay">
<p>Anonymous Hackers:</p>
</div>
</div>
<!-- pic 4 -->
<div class="col-3 card border-0">
<img id="img-anonymous" src="images/home picture/_118803936_united-boom.jpg" alt="Anonymous Hackers"/>
<div class="card-img-overlay">
<p>Anonymous Hackers:</p>
</div>
</div>
<!-- pic 5 -->
<div class="col-3 card border-0">
<img id="img-anonymous" src="images/home picture/_118803936_united-boom.jpg" alt="Anonymous Hackers"/>
<div class="card-img-overlay">
<p>Anonymous Hackers:</p>
</div>
</div>
</div>
</main>
Currently, picture 4 and 5 are not positioning correctly under picture 2 and 3. How can I achieve the desired layout?
