我可以使用一些帮助，因为我是html编码的新手。无论如何， 我已经做了一个带引导的旋转木马。传送带本身工作正常。但在旋转木马中放置一个按钮后（使用top：（px）和right：（px），因为我不知道如何将它放在我想要的地方），但它仍然可以正常工作。直到我开始调整窗口大小。背景变小，但按钮种类保持不变。所以它开始四处移动，曾经是彼此旁边的2个按钮，现在是2个按钮，它们之间有很多空间。在这里，看看我的代码： HTML如何防止在调整窗口大小时移动按钮

基本上是我想要的是按键+的按钮中的文本，当窗口变小也调整。就好像按钮是图像的一部分一样。
谢谢您的时间。 -Michael
由2个非常不同的答案来看，它可能用http://codepen.io或http://jsfiddle.net演示来澄清你的问题是个好主意 – ryantdecker
可能与[此问题]重复（http://stackoverflow.com/questions/1495407/maintain-the对的一-DIV与 - CSS -aspect比）。如果你打算将来编写SCSS而不是纯CSS，你也可以检查[this mixin]（https://css-tricks.com/snippets/sass/maintain-aspect-ratio-mixin/）。 – andreim
