我的問題是,我正在製作一個響應的Web應用程序,我需要一個背景圖像,我想在div中的某個點跟隨/粘貼到背景圖像。對於我來說,無論背景是縮放還是隻是削減兩側,都無關緊要。div跟隨背景圖像
我已經做了小提琴:http://jsfiddle.net/2bhk5n5y/6/
HTML:
<div id="map">
<div id="point1" class="point-location"><div class="point-dot"></div><div class="point-pulse"></div></div>
<div id="point2" class="point-location"><div class="point-dot"></div><div class="point-pulse"></div></div>
<div id="point3" class="point-location"><div class="point-dot"></div><div class="point-pulse"></div></div>
</div>

希望我的問題是非常明顯的,否則就問。
對不起,這麼長時間來回答。我發現我有另一個問題,我使用bootstrap,因爲它有點不同,我做了一個檢查: http://jsfiddle.net/2bhk5n5y/8/ 任何想法如何解決這個問題?它只是一個垂直問題 –
我想你的意思是滾動時的問題,只是從你的背景中刪除固定的屬性,所以它也滾動以及 http://jsfiddle.net/2bhk5n5y/9/ –
確定它的工作原理。謝謝! –
