私は自分のdivを中心にして画面の80％を占めたいと思っています。最大ウィンドウサイズでは正常に動作していますが、ウィンドウのサイズを変更すると画像divが非常に小さくなります。
<body style="background-image:url('img/Mesh2.png');background-repeat:no-repeat; background-size: cover; width=:'100%'">
<h1>iSlider</h1>
<div id="myImageFlow" class="imageflow">
<div id="front">Initialy This is Front </div>
