Question

我试图让两个文本框以及三个图像在页面加载后立即淡入。我已经尝试过使用.onload的一些jQuery，但我似乎无法弄明白。

您没有在页面源中包含jQuery，因此无法使用它。

还要淡化元素，首先需要隐藏它们，通过css

.all_home {    
  display:none;
}

或javascript

jQuery('.all_home').hide().fadeIn(200);

另请注意，jQuery为文档就绪调用提供了便捷的快捷方式：

jQuery(function () {
  // I'm called when the document loaded
})

当页面加载时，如何让这个div淡入？
