我正在为客户制作一个作品集网站，因此让响应式图像发挥作用非常重要。在我将设计转换为 WordPress 之前，一切都 100% 正常工作，但我刚刚安装了名为 Wooslider 的 WordPress 插件，它基于 Flexslider。它对图像有一些问题，将它们放大直到它们真正像素化，它不断地将图像扩展超过其保存的大小。
使用此插件制作幻灯片有两种方法，一种是将所有附加图像添加到帖子和页面上，或者创建每个单独的幻灯片（就像处理帖子一样，并按类别将它们全部连接起来）
我尝试了该插件的 CSS，并解决了由附加图像创建的幻灯片的问题，他们使用了 width: 100% 而不是 max-width: 100% - 我认为另一个属性也会出现这种情况其他地方，但到目前为止还没有运气。我也尝试过在某些地方添加 height: auto 但仍然没有运气。
这是该插件的两个 CSS 代码

任何帮助将不胜感激，干杯
ichabod1799 提供的上述 CSS 覆盖非常适合我。
.slides img { max-width: 100%; height: auto; width: auto; margin: 0 auto;}
从尝试解决此问题的阅读中可以看出，flexslider 在某些时候向包含图像高度和宽度的图像添加了样式属性，导致任何旨在改变尺寸的 CSS 变得无用。
我只是在调用初始化 flexslider 之后添加了这个：
$(this).find('li img').removeAttr('style');
这会从图像中删除任何样式属性，然后可以通过 CSS 控制宽度。
