使用Bootstrap 4 beta。
我的響應式navbar在左側包含一個navbar品牌的標志,在右側包含一個鏈接的內嵌菜單。當視口改變時,導航條正確地折疊,但是徽標沒有像它應該的那樣收縮。這將強制漢堡包在最小視窗的徽標下換行。
我希望徽標縮小到不需要包裹托格勒按鈕的程度。

我向父div添加了一個id,并添加了以下媒體查詢:
@media screen and (max-width: 340px){
#mig-header > a {
max-width: 200px;
}
#mig-header > button {
padding: 0.25rem;
}
}
它完美地工作。
這讓我在手機上縮小了logo:
.navbar-brand img {
max-width: 100%;
}
你應該像這樣為你的標志設置固定的尺寸:

<!-- Just an image -->
<nav class="navbar navbar-light bg-light">
<a class="navbar-brand" href="#">
<img src="https://placehold.it/60" width="30" height="30" alt="">
</a>
</nav>
