即時試圖複製這個圖像作爲一個練習。 original image自舉4 - 3的圖像和一個形式內嵌
但是，現在它看起來是這樣的。 current homepage
基於我的html文件，在'banner'評論下，我創建了一個'jumbo div'，這樣它裏面的所有元素都包含在全寬dekstop中。然後，在'jumbo div'下，我創建了一些'col-sm-n容器'，這樣我的'jumbo div'中的元素就佔用了我分配的空間量。
所以，我的問題，這是我做它來實現，就像原始圖像的正確方法。如果是的話，我做錯了什麼，因爲在導航欄之後存在巨大的差距，而這些元素沒有內聯。

不是很懂，但確定我會盡力玩弄每個IMG浮動。 –
您使用的塊是引導程序（因此浮動已經存在）。在圖像上使用（最大寬度：100％），以便它們位於框內並完全顯示。或者在圖像位於的盒子上使用（溢出：隱藏），以便圖像不顯示在盒子外面。 – wikijames
