單擊Navbar-Toggle按鈕使頁面向下移動

Question

我正在建立一個網站，所以我可以練習我的網絡技能，但我遇到了一個問題。 問題是當網頁在移動設備上時，例如導航欄崩潰，因此它適合設備，但當他們點擊導航欄切換按鈕時，鏈接會越過我擁有的標題的頂部，我不希望這樣做發生。 我想要發生的是當他們點擊它時，如果你理解我的意思，它會將所有元素向下移動。

如果你不去這個網站 - > www.thestartupguys.co.uk < - 並縮小頁面，直到你必須切換導航欄，然后切換它，你看到標題圖像向下移動。

    display: inline;
    text-transform: uppercase;
    height: 50px;
}
