HTML CSS 列表样式更改

Question

我想在我的代码中使用 list 来获得以下输出 -

[1]. This is my line one
[2]. This is my line two
[3]. this is my line three, which is very very long and is not justified when used under list. 

我使用了以下代码。但是没有用

<ol list-style-type: [decimal];>
<li>This is my line one</li>
<li>This is my line two</li>
<li>this is my line three, which is very very long and is not justified when used under list.</li>
</ol>

我是 html 和 css 编码的新手。! 我现在面临的问题是，当我使用这种风格时，长句在单个数字下是不合理的。这是它现在的样子:image.ibb.co/e8Nfda/image.png 如何证明我的台词正确？

已根据您的要求更新:

ol { list-style: none; 
    counter-reset:array;}
   ol li{text-indent: -2em;}
    ol li:before {
    counter-increment:array;
    content:"[" counter(array) "]. ";
    }

    <ol>
    <li>This is my line one This is my line one This is my line one This is my line one This is my line one This is my line one</li>
    <li>This is my line two</li>
    <li>this is my line three</li>
    </ol>
