Why is the sizing property of Bootstrap not applying to images when using h-100? When I try to style them inline, everything works as expected, but setting it as h-100 doesn't work for the images. Can someone please explain this issue?
<div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="carousel-item active">
<img class="d-block w-100 h-100" src="img/hero-bg_1.jpg" alt="First slide">
<h1> Denim Jackets </h1>
</div>
<div class="carousel-item">
<img class="d-block w-100" src="img/hero-bg_2.jpg" alt="Second slide" style="height: 100vh">
<h1> text on the second page </h1>
</div>
<div class="carousel-item">
<img class="d-block w-100" src="img/hero-bg_3.jpg" alt="Third slide" style="height: 100vh">
<h1> text on the third page </h1>
</div>
</div>
<a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>Any insights would be greatly appreciated!
