使图片库对移动设备有响应？

Question

我一直在使我的新网站尽可能快速响应。我得到了我的徽标，通过使用“style = max-width：100％”响应不同的sice屏幕，它完美地运行。但是，当我将它添加到我的图库时，它不起作用。当他们想要彼此相邻的时候，我总是把它们放在下面的图像上。这是我正在使用的HTML;

<div align="center"> 
<section class="slide" style="max-width: 100%">         
<strong> <H2> Featured Work </H2> </strong>

        <div class="stage">
        <a href="#" class="element feature1"><a>
        <a href="#" class="element feature2"><a>
        <a href="#" class="element feature3"><a>
        <a href="#" class="element feature4"><a>


    </section>
    </div>

这是CSS;

.slide {
  max-width: 2000px;
  width: 100%;
  margin: 70px auto 0;
  opacity: 0;
  position: relative;
  -webkit-transition: all 0.25s ease-in-out;

  -webkit-animation: 1s appear 1 forwards;

.element.feature1 {
