Creating a Custom Tooltip Component with Tailwind CSS (without JavaScript)

Creating the Tooltip Component

Let’s start by defining the tooltip Blade component using Tailwind CSS classes. Here’s the code for the tooltip component:

// tooltip.blade.php
<span class="opacity-0 group-hover:opacity-100 max-w-md pointer-events-none absolute -top-7 left-0 w-max rounded bg-gray-900 px-2 py-1 text-sm font-medium text-gray-50 shadow transition-opacity">
    // $slot directive is a placeholder for the content inside the component tags
    
</span>

The above code snippet represents the tooltip container. It has classes for positioning, styling, and transitions. The slot directive is a placeholder for the content inside the component tags.

Notice the first two classes: opacity-0 and group-hover:opacity-100. They control the visibility of the tooltip.

• The opacity-0 class sets the opacity of the tooltip to 0, making it invisible.
• The group-hover:opacity-100 class sets the opacity to 100 when the parent element is hovered over.

This Tailwind CSS utility class allows us to apply styles to child elements based on their parent’s hover state.

Implementing the Tooltip

Now that we have our tooltip component, let’s use it in a practical example:

<div class="group relative w-max flex flex-nowrap cursor-pointer">
    <span>
        Text with tooltip
    </span>
    <x-heroicon-o-exclamation-circle/>
    <x-tooltip>
        This is a tooltip.
    </x-tooltip>
</div>

In the above code, we have a container element with a group class from Tailwind CSS. This class enables us to apply styles to child elements based on their parent’s hover state. Inside the container, we have a label, an icon from the Heroicons library, and our tooltip component (<x-tooltip>) with its content.

Conclusion:

In this tutorial, we learned how to create a custom tooltip component using Tailwind CSS without any JavaAscript. By leveraging the power of Tailwind CSS utility classes, we were able to style and position the tooltip with ease.
