问题是：我使用parrallx滚动，所以我有z-index在页面现在当我尝试通过Bootstrap弹出框模式，让他看起来像这样www.dropbox/s/42tzvfppj4vh4vx/Screenshot%202013-11- 11％2020.38.36.png
，你可以看到，盒子模式不是ontop，任何鼠标点击禁用它。 如果我禁用此CSS代码：
#content { color：＃003bb3; position：relative; margin：0 auto; width：960px; z-index：300; background：url（'../ images / parallax-philosophy-ltl.png'）top center; }只是为了注意，Bootstrap defalut .modal是z-index：1050，所以我不明白为什么它不在所有其他上下文之上。
-modal：

< li>< a class =launchdata- toggle =modalhref =＃launch> Approve< / a>< / li& EDIT h2>解决方案找到，如果任何人都遇到相同的问题。 这是方式：添加data-backdrop =false到section或div包含的模态例如：< section id =launchclass =模式隐藏褪色data-backdrop =false> 注意它没有得到灰色的背景，所以它是一个肮脏的解决方案，将很高兴听到。
解决方案问题几乎总是与嵌套z索引有关。作为示例：
< div style =z-index：1> 某些内容A < div style =z-index：1000000000> 一些内容B < / div> < / div> < div style =z-index：10> 一些内容C < / div>如果你看看z-index只有你会期望B，C，A，嵌套在一个明确设置为1的div中，它将显示为C，B，A。
设置位置：fixed锁定该元素的z-index和所有的孩子，这就是为什么改变可以解决问题。
解决方案是找到具有z索引集的父元素，并调整设置或者移动内容，使图层和它们的父容器按照你想要的方式叠加。 Firefox中的Firebug在最右边有一个名为布局的选项卡，您可以快速查看父元素并查看z-index的设置位置。
The issue is: I'm using parrallx scrolling, so I have z-index in the page now when I try to popup a box-modal by Bootstrap I get him to look like this www.dropbox/s/42tzvfppj4vh4vx/Screenshot%202013-11-11%2020.38.36.png
as you can see, the box-modal isn't ontop and any mouse click disables it. if I disable this css code :
#content { color: #003bb3; position: relative; margin: 0 auto; width: 960px; z-index: 300; background: url('../images/parallax-philosophy-ltl.png') top center; }the box modal works. just to notice, Bootstrap defalut .modal is z-index:1050 , so I cant understand why it's not ontop of all other context.
thats the box-modal:
<section id="launch" class="modal hide fade"> <header class="modal-header"> <button type="button" class="close" data-dismiss="modal">×</button> <h3>אשר הגעה לחתונה </h3> </header> <div class="modal-body"> <form method="post" action="/update" id="myForm2"> <input type="radio" id="yes_arrive" name="arrive" checked="checked" value="yes">מגיע<br> <p><input type="text" required name="fsname" value="" placeholder="הכנס שם פרטי ומשפחה "></p> <p>כמה אנשים מגיעים? </p> <select name="number" id="number"> <option value="0">0</option> <option value="1">1</option> <option value="2">2</option> </select> <hr/> <input type="hidden" name="title" id="title" value="{{title}}"> <input type="radio" name="arrive" id ="no_arrive" value="no">לא מגיע <p>סיבה לאי הגעה</p> <input type="text" name="no_arrive_reason" placeholder="קצר ולעניין, לא שדה חובה"> <hr/> <p class="submit"><input type="submit" name="submit" value="שלח"></p> </form> </div> <footer class="modal-footer"> <button class="btn btn-primary" data-dismiss="modal">Close</button> </footer> </section>and I trigger him from top menu:
<li><a class="launch" data-toggle="modal" href="#launch">Approve</a></li>thanks ahead.
EDITSolution found if anyone falls to the same problem. this is the way: add data-backdrop="false" to section or div that you contain the modal with e.g: <section id="launch" class="modal hide fade in" data-backdrop="false"> notice that it doesn't get the gray background that way, so it's kinda a dirty solution, will be happy to hear of a better one.
解决方案The problem almost always has something to do with "nested" z-indexes. As an Example:
<div style="z-index:1"> some content A <div style="z-index:1000000000"> some content B </div> </div> <div style="z-index:10"> Some content C </div>if you look at the z-index only you would expect B,C,A, but because B is nested in a div that is expressly set to 1, it will show up as C,B,A.
Setting position:fixed locks the z-index for that element and all its children, which is why changing that can solve the problem.
The solution is to find the parent element that has the z-index set and either adjust the setting or move the content so the layers and their parent containers stack up the way you want. Firebug in Firefox has a tab in the far right named "Layout" and you can quickly go up the parent elements and see where the z-index is set.
