How to use HTML and CSS to implement tabbed layout

Tabbed layout is a common page layout method, which divides the page into multiple tabs, each The label corresponds to a piece of content, and different content is displayed by switching the label. In this article, we will introduce how to use HTML and CSS to implement tabbed layout and give specific code examples.

    <li>Create HTML structure

First, we need to create an HTML file and define the required tags and content. The following is an example HTML structure: 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>标签式布局</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div class="container">
        <ul class="tabs">
            <li class="tab">标签1</li>
            <li class="tab">标签2</li>
            <li class="tab">标签3</li>
        </ul>
        <div class="content">
            <div class="tab-content">内容1</div>
            <div class="tab-content">内容2</div>
            <div class="tab-content">内容3</div>
        </div>
    </div>

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

In the above HTML structure, we use <ul></ul> and <li> tags to create tab navigation column, use

tags to wrap the label content. Each tag content uses the
tag and adds a corresponding class name.
    <li>Create CSS styles

Next, we need to use CSS to define the styles of labels and content. The following is an example CSS style: 

.container {
    width: 800px;
    margin: 0 auto;
}

.tabs {
    list-style: none;
    padding: 0;
    margin: 0;
}

.tab {
    display: inline-block;
    padding: 10px 20px;
    background-color: lightgray;
    cursor: pointer;
}

.tab:hover {
    background-color: gray;
    color: white;
}

.tab-content {
    display: none;
    padding: 20px;
    border: 1px solid lightgray;
}

.content .tab-content:first-child {
    display: block;
}

In the above CSS style, we define the style of the entire layout container through the .container class. The .tabs class defines the style of the tab navigation bar, the .tab class defines the style of each tab, and the .tab-content class defines the tab content. style.

In the last row of styles, we use the CSS selector first-child to display the first label content, and the display attribute of other label contents is set to none, so that only the first label content is displayed initially.

    <li>Add JavaScript interaction

To implement the label switching function, we need to use JavaScript to handle the click event of the label. The following is an example JavaScript code: 

window.addEventListener('load', function() {
    var tabs = document.querySelectorAll('.tab');
    var tabContents = document.querySelectorAll('.tab-content');

    for(var i = 0; i < tabs.length; i++) {
        tabs[i].addEventListener('click', function() {
            var tabClass = this.getAttribute('class');

            for(var j = 0; j < tabContents.length; j++) {
                tabContents[j].style.display = 'none';
            }

            var contentId = '.' + tabClass + '-content';
            var content = document.querySelector(contentId);
            content.style.display = 'block';
        });
    }
});

In the above JavaScript code, we first obtain all tags and content elements, and then bind a click event to each tag through a loop. When clicking a label, all content is first hidden, and then the corresponding content is found based on the clicked label class name and displayed.

    <li>Result display

The above is the complete code to implement tabbed layout. Run the HTML file and you will see a page containing three tags and corresponding content. Click on different labels and the corresponding content will be displayed.

Summary:

It is not complicated to implement tabbed layout using HTML and CSS. By creating an HTML structure, defining CSS styles, and adding some JavaScript interaction, you can implement a simple and practical tabbed layout. Hope this article helps you!
