中央引導帶Navbar品牌徽標

Question

我正在嘗試將Bootstrap navbar品牌徽標的中心居中，但似乎稍微向右推...如何解決此問題？

Answer 1

你可以試試看

我所做的是創建了一個div（ .navbar-logo ），該文件將包圍.navbar-brand然后應用Flexbox將徽標居中。

然后我將一些CSS實施到.navbar-toggle以使其定位。

然后將width設置為.navbar-header以在桌面視圖中進行對齊。

希望這可以幫助。

Answer 2

.navbar-brand{
    display: flex;
    justify-content: center;
    width: 100%;
    left: 0;
}

希望這段代碼能解決您的問題
