Question

我正在使用https://ready.mobi测试所有设备的网站。我对正确设置索引标头上的图像感兴趣。目前，该图片在所有设备上都不看起来不错。此外，蓝色和橙色按钮彼此之间距离太近，并且图片看起来太大（您必须滚动才能看到它）。

当前结果：

我已经设置了媒体查询来处理此问题。显然，它们不能很好地工作。

Answer 1

写下：

@media (max-width: 480px) {

代替：

@media (min-width: 320px) and (max-width: 480px) {

Answer 2

在html中，您可以为不同尺寸的设备指定不同的图像：

<picture>
   <source media="(max-width: 480px)" srcset="yoursourceMobile.jpg">
   <source media="(max-width: 2056px)" srcset="yoursource.jpg">
   <img src="yoursource.jpg">
</picture>

横幅图片在移动设备上的加载尺寸更大
