很抱歉粘貼長代碼，但我希望我已經提供了一切可能。我已經嘗試了一些以前的問題方法，例如 display-inline、display-flexbox 等，但它們似乎都不起作用。

使用 Div 將 Night Mode On 文本居中對齊，也使用 nbsp；否則它正在破裂。

uj5u.com熱心網友回復：

您可以使用display:flex;andjustify-content:center;將其定位在中心

   .aligner{   
        position: relative;
        display: flex;
        margin-right: 6vw;
        justify-content: center;
    }

我編輯了你的一些 CSS。彎曲它然后居中。讓我知道這是不是你的意思？
