我在Bootstrap 4.0 Beta項目中使用split button dropdown。我遇到了一個問題，我無法弄清楚如何縮小分割的btn-group組件之間的差距。Bootstrap 4：左右分離按鈕下拉元素之間的閉合間隙
我試圖讓btn-group的左側部分以鄰接與右邊部分的
我試着利潤率，填充等碴的各種迭代，但我無法讓它們與零空間連續。下面是我用撥弄了CSS的一部分：
.btn-group > .dropdown-toggle {
margin-left: 0;
padding-left: 0;
}

你能降低代碼爲[MCVE] （強調最小化）默認的分割按鈕（來自框架）不表現這種方式，所以我想知道你添加了什麼創建額外的差距... – ochi
