我想将这些输入文本框精确地放置在 Bootstrap 中的图像上。这些输入文本框将相对于背景中的图像和彼此定义。到目前为止，我已经能够为容器添加背景图像并在其上放置输入文本字段，但是根据上述标准的放置一直是个问题。请帮忙。

最佳答案

我知道您指的是 bootstrap 的默认样式表，但您需要先了解几件事。为了根据您自己的喜好在 bootstrap 中操纵任何内容的位置或外观，您必须制作一个自定义样式表，然后确保在您的 bootstrap 样式表之后引用它，以便 bootstrap 不会否定您的样式。然后你必须知道足够的 css 才能根据你的喜好改变你的风格。您当前正在使用 javascript 将背景图像放置在 div 中，这在语义上是不正确的。这是一个解释基础知识的链接，但您确实需要了解更多有关 css 的知识才能使用 Bootstrap 完成您想要的操作。 http://bootstrapbay.com/blog/customize-bootstrap/
