HTML, CSS, and jQuery: A technical guide to creating a fluid layout

In modern web design, fluid layout has become a very popular design trend. Compared with fixed layouts, fluid layouts can adapt to changes in screen size and therefore provide a better user experience. This article will provide you with a detailed technical guide to creating fluid layouts using HTML, CSS, and jQuery, complete with specific code examples.

HTML Structure

First, we need to use a suitable HTML structure to build a fluid layout. Generally speaking, the structure of fluid layout is usually divided into header, navigation bar (nav), content area (content) and bottom (footer). Here is an example of a basic HTML structure:

<!DOCTYPE html>
<html>
<head>
    <title>流式布局示例</title>
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
    <header>
        <!-- 头部内容 -->
    </header>

    <nav>
        <!-- 导航栏内容 -->
    </nav>

    <div class="content">
        <!-- 内容区域 -->
    </div>

    <footer>
        <!-- 底部内容 -->
    </footer>

    <script src="jquery.js"></script>
    <script src="script.js"></script>
</body>
</html>

CSS Styles

Next, we will use CSS styles to define the appearance of the fluid layout. By using percentages and responsive units (such as vw, vh) to define size and position, we can achieve the adaptive nature of fluid layout. The following is a basic CSS style example:

/* 头部样式 */
header {
    height: 10vh;
    background-color: #333;
    color: #fff;
}

/* 导航栏样式 */
nav {
    height: 8vh;
    background-color: #666;
    color: #fff;
}

/* 内容区域样式 */
.content {
    width: 80vw;
    margin: 0 auto;
    padding: 20px;
}

/* 底部样式 */
footer {
    height: 6vh;
    background-color: #999;
    color: #fff;
}

jQuery script

In addition to using CSS styles to define the layout appearance, we can also use jQuery scripts to achieve some interactive effects . For example, we can use jQuery to implement the drop-down menu effect of the navigation bar. The following is a basic jQuery script example:

$(document).ready(function() {
    // 导航栏下拉菜单
    $('.nav-item').click(function() {
        $(this).children('.dropdown-menu').toggle();
    });
});

Optional: Media queries

To better adapt to different screen sizes, we can use CSS media queries to Define different layout styles. For example, we can use vertical layout on small screen devices and horizontal layout on large screen devices. The following is a basic media query example:

/* 小屏幕设备 */
@media screen and (max-width: 600px) {
    /* 垂直布局 */
    .content {
        width: 90vw;
    }
}

/* 大屏幕设备 */
@media screen and (min-width: 1200px) {
    /* 水平布局 */
    .content {
        width: 60vw;
        float: left;
    }

    /* 侧边栏样式 */
    .sidebar {
        width: 30vw;
        float: right;
    }
}

The above is a basic technical guide to using HTML, CSS and jQuery to create fluid layouts. With appropriate HTML structure, CSS styles, and jQuery scripts, we can create fluid layouts that adapt to screen sizes and adapt to different screen devices through media queries.
