このチュートリアルを、私が達成しようとしていることに使用できるものに変更する際に問題が発生しています。http://thecodeplayer.com/walkthrough/pure-css3-animated-clouds-background
雲を泡に変えて、左から右ではなく下から上にしたいと思います。
それはバックグラウンドに非常に奇妙なことをしています...バブルとともにBGグラデーションを移動している理由を特定するのを手伝ってくれる人はいますか?
ここに私のCSSがあります
body {
/*To hide the horizontal scroller appearing during the animation*/

そして私のHTML
<div id="clouds">
<div class="cloud x1"></div>
<!-- Time for multiple clouds to dance around -->

<div class="cloud x3"></div>
<div class="cloud x4"></div>
<div class="cloud x5"></div>
</div>
