Laravel's Blade templating engine is a staple for developers who want to craft beautiful and dynamic user interfaces with ease. When paired with Tailwind CSS, a utility-first CSS framework, the potential for rapid, responsive design is limitless. However, managing CSS classes within Blade components can become cumbersome, especially when dealing with class collisions or conditional styling. This is where the [tailwind-merge-laravel](https://github.com/gehrisandro/tailwind-merge-laravel) package comes into play, offering a streamlined way to merge Tailwind CSS classes directly within your Blade components. 

In this blog post, we'll explore how to utilize this package to create a Blade component with a `<div>` and heading tags (`h1` to `h6`), each with its own set of Tailwind CSS classes.

**Installing the [tailwind-merge-laravel](https://github.com/gehrisandro/tailwind-merge-laravel) Package**
Before we dive into the Blade component, we need to ensure that the [tailwind-merge-laravel](https://github.com/gehrisandro/tailwind-merge-laravel) package is installed in our Laravel project. This package provides several helper functions that intelligently merges Tailwind CSS classes, taking into account responsive prefixes, pseudo-class variants, and more. To install the package, run the following command in your terminal:

```bash
composer require gehrisandro/tailwind-merge-laravel
```

**Crafting the HeadingGroup Component**
With the package installed, let's create a new Blade component called **`HeadingGroup`**. This component will render a `<div>` wrapper around our heading tags, each with the ability to have its own merged set of Tailwind CSS classes.

First, generate the component using Laravel's Artisan CLI:

```BASH
php artisan make:component HeadingGroup
```

Next, edit the generated Blade view file (`resources/views/components/heading-group.blade.php`) to include the `<div>` and heading tags:

```BLADE
{{-- resources/views/components/heading-group.blade.php --}}

<div {{ $attributes->withoutTwMergeClasses()->twMerge('text-left') }}>
    @if (isset($h1) && !empty($h1))
    <h1 {{ $attributes->twMergeFor('h1', 'text-6xl') }}>{{ $h1 }}</h1>
    @endif

    @if (isset($h2) && !empty($h2))
    <h2 {{ $attributes->twMergeFor('h2', 'text-4xl') }}>{{ $h2 }}</h2>
    @endif

    @if (isset($h3) && !empty($h3))
    <h3 {{ $attributes->twMergeFor('h3', 'text-2xl') }}>{{ $h3 }}</h3>
    @endif

    @if (isset($h4) && !empty($h4))
    <h4 {{ $attributes->twMergeFor('h4', 'text-1xl') }}>{{ $h4 }}</h4>
    @endif

    @if (isset($h5) && !empty($h5))
    <h5 {{ $attributes->twMergeFor('h5', 'text-xl') }}>{{ $h5 }}</h5>
    @endif

    @if (isset($h6) && !empty($h6))
    <h6 {{ $attributes->twMergeFor('h6', 'text-lg') }}>{{ $h6 }}</h6>
    @endif
</div>
```
In this snippet, each `h*` tags has its own `$slot`, this is used to inject content into each heading tag. The `twMergeFor()` function is called on $attributes to merge with tag's default classes with any additional classes passed to the component. The `withoutTwMergeClasses()` method is a custom method that you would need to define to exclude certain classes from the merging process, ensuring that the `<div>` gets only the classes you specify.

**Using the HeadingGroup Component**
To use the **`HeadingGroup`** component in your Blade templates, you can simply include it with the desired classes:

```BLADE
<x-heading-group 
    class="mx-auto text-center text-black font-bold"
    class:h1="text-6xl"
    class:h2="text-4xl text-blue-600 font-light"
>
    <x-slot name="h1">
        Welcome to Our Blog!
    </x-slot>

    <x-slot name="h2">
        About our blog...
    </x-slot>
</x-heading-group>
```
