    A PR was made, something like this:

    const data = [
       {
        question: 'How are you?',
        answer: `I'm good because:<br/>
        <ul style="padding-left:20px;list-style-type: disc;">
          <li>Something something bla bla bla</li>
        </ul>`
      },
      {
        question: 'Where are you from?',
        answer: `I'm good because:<br/>
        <ul style="padding-left:20px;list-style-type: disc;">
          <li>Something something</li>
        </ul>`
      }
    ]
    
    return (
      <div>
        {data.map((d, i) => {
          return (
            <div key={i} dangerouslySetInnerHTML={{__html: d}} />
          )
        }}
      </div>
    )
    

    The problem in that PR is that the data items are polluted by the style. It makes it harder for developers to read the data and not to mention the repetition. A better way is to keep the styling out of the data. Instead, let the parent component styles the HTML elements that appear in the data (ul element in this example) by using Tailwind's arbitrary variants. So it becomes like this:

    const data = [
       {
        question: 'How are you?',
        answer: `I'm good because:<br/>
        <ul>
          <li>Something something bla bla bla</li>
        </ul>`
      },
      {
        question: 'Where are you from?',
        answer: `I'm good because:<br/>
        <ul>
          <li>Something something</li>
        </ul>`
      }
    ]
    
    return (
      <div className="text-slate-500 [&>ul]:list-outside [&>ul]:list-disc [&>ul]:pl-5 [&>ol]:list-outside [&>ol]:list-decimal [&>ol]:pl-8">
        {data.map((d, i) => {
          return (
            <div key={i} dangerouslySetInnerHTML={{__html: d}} />
          )
        }}
      </div>
    )
