内容图文
我在this tutorial页面上设置了一个动画CSS按钮.该按钮出现在我的页面上,但没有动画.但是,当它在外面< div id =“wrapper”>翻转动画确实有效,但是我无法在页面上找到我想要的地方.我已经在index.html和style.css中包含了与按钮相关的代码,并突出显示了按钮的< div>在我的index.html中.如果你需要CSS包装或主要或其他什么,让我知道,我会尝试挖掘它.
您可以在http://suchryan.com/gtd/#download看到我的问题的实时版本,以及我在http://suchryan.com/working/尝试实现的版本.
请让我知道我错过了什么,我已经被困在这几个小时了:(

Grab the Diamonds is a simple 2D platformer that I created in my first year of college. It was written in GLBasic
and is loosely based on the game Minecraft. It is currently unfinished, although I may choose to continue with
it someday. The game is fully functional, yet only the first level is able to be completed as the others are
unfinished. None of the images are compressed, so the file size is quite large (36Mb). A
VirusTotal Scan can be <a href="http://goo.gl/iaTdiY">found here</a> for anybody that is a little skeptical.

.downbutton:active .bottom
{
margin: -20px 0 0 10px;
}
.downbutton:active .top
{
margin: -70px 0 0 10px;
}
解决方法:
这不是JS而是CSS问题：
/* First add the following rules to your .downbutton a style rules */
position: relative; /* so z-index is working */
z-index: 2; /* increase it to 'hide' the additional infos */
/* Second change .downbutton p z-index (currently -1) */
z-index: 1; /* to set them 'behind' the button but in front of bg */
现在你已经可以看到p元素,并且悬停将再次“工作”(它一直有效)但是p标签根本不可见.标签仍然处于错误的位置(在容器中左对齐,没有居中.您可以通过将两个p标签居中放在.downbutton中来固定(左：50％; margin-left：-half-width-of-p) -tag)或将整个.downbutton容器本身居中.
