You can use a combination of Bootstrap's grid system and custom CSS. Below is an example of how you can achieve this:
HTML:
<div class="hero-image" style="background-image: url('your-image.jpg');">
<div class="container">
<div class="row">
<div class="col-xs-12 text-center">
<h1 class="hero-text">Centered Text</h1>
<p class="hero-subtext">Any subtitle</p>
</div>
</div>
</div>
</div>
CSS:
.hero-image {
position: relative;
height: 400px;
background-size: cover;
background-position: center;
display: flex;
align-items: center;
justify-content: center;
color: white;
}
.hero-text {
font-size: 3em;
font-weight: bold;
}
.hero-subtext {
font-size: 1.5em;
margin-top: 10px;
}
