Introduction

Creating a user-friendly interface is essential for any web application. One effective way to organize content is through tabs. In this guide, we’ll explore how to create pure CSS tabs utilizing the details element, CSS Grid, and Subgrid features. This approach is not only efficient but also enhances accessibility and performance.

  • Creating a tabbed interface with CSS Grid

  • Best practices for styling tabs

Prerequisites

Before diving in, make sure you have a basic understanding of CSS and HTML. You can also use the CSS Minifier to optimize your stylesheets.

Step 1: Basic HTML Structure

To get started, we need a simple HTML structure. Below is an example of how to set up your tabbed interface using the <details> element.

<div class="tabs">
    <details>
        <summary>Tab 1</summary>
        <div class="content">
            <p>Content for Tab 1</p>
        </div>
    </details>
    <details>
        <summary>Tab 2</summary>
        <div class="content">
            <p>Content for Tab 2</p>
        </div>
    </details>
</div>

Step 2: Styling with CSS Grid

Next, we will style our tabs using CSS Grid. This allows us to create a responsive layout that adjusts according to the viewport size.

.tabs {
    display: grid;
    grid-template-columns: repeat(2, 1fr);
    gap: 1rem;
}

.content {
    border: 1px solid #ccc;
    padding: 1rem;
    display: none;
}

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

Step 3: Utilizing CSS Subgrid

Now let’s implement Subgrid for a nested layout within our tabs. Subgrid allows child elements to align with their parent grid, creating a more cohesive design.

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

Step 4: Final Enhancements

Finally, we can enhance the appearance of our tabs with some additional CSS. Make sure to style the <summary> element for a better user experience.

summary {
    background-color: #f0f0f0;
    cursor: pointer;
    padding: 0.5rem;
    border-radius: 4px;
}

summary:hover {
    background-color: #e0e0e0;
}
