Pure CSS Tabs With Details, Grid, and Subgrid

Introduction

Creating interactive user interfaces is an essential skill for modern web developers. One way to enhance user experience is by implementing tabs, which allow users to switch between different content sections without leaving the page. In this guide, we will explore how to create pure CSS tabs using CSS Grid and CSS Subgrid layouts. We will leverage the <details> and <summary> elements for a clean, semantic approach. Let’s dive in!

What Are Pure CSS Tabs?

Pure CSS tabs are a method of creating tabbed navigation without relying on JavaScript. This approach utilizes only HTML and CSS to manage the visibility of different content sections, making it lightweight and efficient.

Benefits of Using CSS Grid and Subgrid

  • Enhanced Layout Control: CSS Grid and Subgrid provide a flexible layout system that allows precise control over the positioning of elements.
  • Responsive Design: With grid layouts, your tabs can easily adapt to different screen sizes and orientations.
  • Simplified Code: By using pure CSS, you can reduce the amount of code and avoid potential JavaScript conflicts.

Step-by-Step Guide to Create Pure CSS Tabs

1. Setting Up the HTML Structure

<div class="tabs">
    <details>
        <summary class="tab-title">Tab 1</summary>
        <div class="tab-content">
            Content for Tab 1
        </div>
    </details>
    <details>
        <summary class="tab-title">Tab 2</summary>
        <div class="tab-content">
            Content for Tab 2
        </div>
    </details>
    <details>
        <summary class="tab-title">Tab 3</summary>
        <div class="tab-content">
            Content for Tab 3
        </div>
    </details>
</div>

2. Adding CSS Styles

.tabs {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    gap: 10px;
}

.tab-title {
    cursor: pointer;
    padding: 10px;
    background: #f0f0f0;
    border: 1px solid #ccc;
}

.tab-content {
    padding: 10px;
    border: 1px solid #ccc;
    border-top: none;
    display: none;
}

details[open] .tab-content {
    display: block;
}

3. Utilizing CSS Subgrid

To further enhance the layout, we can utilize CSS Subgrid. This feature allows us to align child elements of the tabs to a shared grid:

.tab-content {
    display: grid;
    grid-template-columns: subgrid;
}

.tab-content div {
    background: #e0e0e0;
    padding: 10px;
}
