Specifically, it becomes essential to understand how to apply negative translation values to achieve the desired effect. If you've ever felt perplexed by this issue, you're not alone!

You also mentioned that one workaround is to create a custom center class in your CSS, looking something like this:

Step-by-Step Implementation

Ensure You Are Using the Right Classes: Make sure you have applied before:-translate-x-1/2 alongside the other Tailwind classes for absolute positioning.

Check Your Tailwind Configuration: If the utility class does not seem to be working, you may have an issue with your Tailwind setup. In some cases, the layer base in your Tailwind configuration might be commented out. Uncommenting it will activate all the necessary utilities.

Final HTML Structure: Your final HTML should look like this:
