It's common practice to add a "Load More" button to a web page using jQuery and CSS to display more content without refreshing the entire page. Here is a detailed explanation on how to do it:

1.HTML Structure:

First, create your HTML structure with a container to hold the content and a "Load More" button.

<div class="container text-center">
	<div class="row">
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
		<div class="col-md-4">
			<div class="content"></div>
		</div>
	</div>
	<a href="" class="load-more">Load More</a>
</div>

Add some basic CSS styles to control the layout and appearance of the container and the "Load More" button.

.container{
  margin:30px auto;
}

.col-md-4{
  display:none;
}

.content{
  background-color:#333;
  height:200px;
  margin:10px 0;
  border:1px solid #ccc;
}

.load-more{
  background-color:#000;
  color:#fff !important;
  padding:5px 10px;
  border-radius:4px;
  font-size:20px;
  margin:50px 0;
  display:inline-block;
}

.load-more:hover{
  background-color:blue;
  text-decoration:none;
}

Include jQuery in your project and use it to handle the "Load More" button functionality.

$(function () {
		$(".col-md-4").slice(0, 3).show();
		$("body").on('click touchstart', '.load-more', function (e) {
			e.preventDefault();
			$(".col-md-4:hidden").slice(0, 3).slideDown();
			if ($(".col-md-4:hidden").length == 0) {
				$(".load-more").css('visibility', 'hidden');
			}
			$('html,body').animate({
				scrollTop: $(this).offset().top
			}, 1000);
		});
	});

I'm done now! The aforementioned HTML, CSS, and JavaScript code allows you to create a "Load More" button that works with CSS and jQuery. To suit your particular use case, alter the increment value and the number of beginning elements.
