bootstrap4 Reboot details summary 美化（点选禁止选中文本，单行隐藏角标，多行后移）

 bootstrap4 Reboot details summary 

优化这块，主要是为了去掉details summary的角标~

所以优化写了一下。

原始HTML

<details>
    <summary>Some details</summary>
    <p>More info about the details.</p>
</details>

        padding-left: 1.15em;
    }

    details summary:focus {
        outline: none;
    }

    details summary.single-line {
        cursor: default;
    }

        details summary.single-line + p {
            display: none;
        }

        /*Chrome*/
        details summary.single-line::-webkit-details-marker {
            visibility: hidden;
        }
        /*Firefox*/
        details summary.single-line:first-of-type {
