27:         role="alert">
28:         A simple light alert—check it out!
29:     </div>
30:     <div class="relative p-4 mb-4 border-[1px] border-[solid] border-[transparent] text-[#141619] bg-[#d3d3d4] border-[#bcbebf]"
31:         role="alert">
32:         A simple dark alert—check it out!
33:     </div>
34: </div>

Notes

For the colors I decided to use the [] syntax to set the exact hex as Bootstrap thus: text-[#141619] bg-[#d3d3d4] border-[#bcbebf]. You can however use Tailwind's color presets [↗].

You may have also noticed the repetition of some utility classes. Tailwind recommends creating reusable styles [↗] whenever this happens.

This can simply be a component function that takes in unique utilities as a parameter and then produces the resulting HTML element with both the common and unique utilities set as a class attribute. For example:

alertComponent.js
01: function alertComponent(textContent, propString) {
02:     return `<div class="relative p-4 mb-4 border-[1px] border-[solid] border-[transparent] text-[#141619] ${propString}"
03:         role="alert">
04:         ${textContent}
05:     </div>`
06: }
07: 
08: alertComponent('A simple dark alert—check it out!', 'bg-[#d3d3d4] border-[#bcbebf]')

It's ultimately up to you and your needs.
