INFORMATION & CODE

Internal tab Links Display

What the Code Does

This code creates an interactive "tabbed content" interface on a webpage. It displays a navigation menu of buttons (tabs) at the top and a container box below them holding different sections of text. When a user clicks a specific tab button, the corresponding section of text is displayed inside the container box while hiding the previously viewed sections, allowing users to switch between different content panels seamlessly without reloading the page.

How it Works

The functionality is split across three standard web technologies: HTML, CSS, and JavaScript. The HTML structures the layout by creating a wrapper for the navigation buttons (.tab_wrap), a container area (.tab_outer), and individual content panels (.tab_inner) assigned with unique IDs (link0 through link3).

The CSS styles these elements to look like a neat, centered widget. Crucially, it hides all content panels by default using display: none; and provides an .active class that uses display: block; to reveal a panel. It also includes styling for button interactions, such as changing text decoration and colors on focus.

The JavaScript adds the interactivity by listening for click events inside the button wrapper. When a button is clicked, the script determines its index position relative to its siblings. It then loops through all the content panels, removes the active class from every single one, and finally applies the active class exclusively to the content panel that matches the index of the clicked button.

How to Use It

To use this code in your own project, copy the HTML snippet into an HTML file (such as index.html), the CSS into a linked stylesheet named styles.css, and the JavaScript into a linked script file named scripts.js (or place them inside appropriate <style> and <script> tags within the HTML document). Ensure that your file paths match. To expand the interface, you can add more <button class="tab"> elements to the HTML along with corresponding <div class="tab_inner" id="..."> content blocks, and the JavaScript will automatically handle the new tabs based on their order.
