我正在使用bootstrap构建一个静态电子商务网站。我想要在手机中打开时连续2个产品，在桌面或i-pad中打开时连续4个产品。
<div class="container">
<div class="row product">
<div class="col-md-3">
<div class="image">
<a href="products.php?q=10020" target="_blank"><img id="10030" src="#"></a>
</div>
</div>
<div class="col-md-3">
<div class="image">
<a href="products.php?q=10020" target="_blank"><img id="10030" src="#"></a>
</div>
</div>
<div class="col-md-3">
<div class="image">
<a href="products.php?q=10020" target="_blank"><img id="10030" src="#"></a>
</div>
</div>
<div class="col-md-3">
<div class="image">
<a href="products.php?q=10020" target="_blank"><img id="10030" src="#"></a>
</div>
</div>
</div>
此页面上有一行以上。请帮我解决这个问题。
你遇到的问题是因为你的引导网格。
我在下面做了一个例子。注意：class =“col-xs-6 col-md-3”
