How to make a dynamic timeline using HTML, CSS and jQuery
How to use HTML, CSS and jQuery to make a dynamic timeline, specific code examples are required
Timeline is a common way to display the time sequence and event flow method, very suitable for displaying historical events, project progress, etc. Using HTML, CSS and jQuery technology, you can easily create a dynamic timeline effect. This article will introduce how to use these techniques to achieve a simple timeline effect and provide specific code examples.
First, we need to create a basic timeline structure in HTML. The following is a code example:
<!DOCTYPE html>
<html>
<head>
<title>动态时间轴</title>
<link rel="stylesheet" type="text/css" href="styles.css">
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div class="timeline">
<div class="timeline-items">
<div class="timeline-item">
<div class="timeline-item-content">
<h2 id="事件">事件1</h2>
<p>事件1的详细描述</p>
</div>
</div>
<div class="timeline-item">
<div class="timeline-item-content">
<h2 id="事件">事件2</h2>
<p>事件2的详细描述</p>
</div>
</div>
<div class="timeline-item">
<div class="timeline-item-content">
<h2 id="事件">事件3</h2>
<p>事件3的详细描述</p>
</div>
</div>
</div>
<div class="timeline-progress"></div>
</div>
</body>
</html>In the above HTML code, we created a .timeline container, which contains a .timeline-items container and a .timeline-progressProgress bar. .timeline-items The container is used to place events on the timeline. Each event is represented by .timeline-item, and the details of the event are placed in .timeline-item- contentContainer.
Next, we use CSS styles to beautify the appearance of the timeline. The following is a code example:
.timeline {
position: relative;
margin: 50px auto;
width: 800px;
}
.timeline-items {
position: relative;
}
.timeline-item {
position: relative;
margin-bottom: 50px;
padding: 20px;
background: #f1f1f1;
}
.timeline-item-content {
display: inline-block;
vertical-align: top;
}
.timeline-progress {
position: absolute;
width: 4px;
background: #666;
top: 0;
bottom: 0;
left: 50%;
transform: translateX(-50%);
}In the above CSS code, we set the basic style of the .timeline container and beautify .timeline-item and ## The appearance of #.timeline-progress.
$(document).ready(function() {
var timelineItems = $(".timeline-items .timeline-item");
var progress = $(".timeline-progress");
// 设置进度条的初始位置
progress.css("height", timelineItems.length * 100);
// 监听滚动事件，更新进度条位置
$(window).scroll(function() {
var scrollTop = $(this).scrollTop();
var windowHeight = $(this).height();
var documentHeight = $(document).height();
var timelineOffset = $(".timeline").offset().top;
var progressHeight = windowHeight * ((scrollTop - timelineOffset) / (documentHeight - windowHeight));
progress.css("top", scrollTop - timelineOffset);
progress.css("height", progressHeight);
});
});The above is the detailed content of How to make a dynamic timeline using HTML, CSS and jQuery. For more information, please follow other related articles on the PHP Chinese website!

【Rust Self-study】Introduction
Apr 04, 2025 am 08:03 AM
1.0.1 Preface This project (including code and comments) was recorded during my self-taught Rust. There may be inaccurate or unclear statements, please apologize. If you benefit from it, it's even better. 1.0.2 Why is RustRust reliable and efficient? Rust can replace C and C, with similar performance but higher security, and does not require frequent recompilation to check for errors like C and C. The main advantages include: memory security (preventing null pointers from dereferences, dangling pointers, and data contention). Thread-safe (make sure multi-threaded code is safe before execution). Avoid undefined behavior (e.g., array out of bounds, uninitialized variables, or access to freed memory). Rust provides modern language features such as generics
