如何在html ul li标签中进行缩进

我有无序列表,里面有项目符号.我需要缩进列表项目.但是对于长时间运行的文本,样式不能按预期工作.我应该在边框内对齐它.这是css代码

ul{
    BACkground-color: #FFFFFF;
    border: 1px solid black;
    border-radius: 3px 3px 3px 3px;
    list-style: disc inside none;
    padding: 10px;
}

这是HTML示例

<div style="padding:20px">
    <ul>
        <li>Should be minimum of 8 characters</li>
        <li>A long running text A long running text A long running text A long running text A long running text</li>
        <li>Should have at least one number</li>
    </ul>
</div>
