If I have a navbar in bootstrap with the items Home | About | Contact How do I set the active class for each menu item when they are active? That is, how can I set class="active" when the angular route is at #/ for home #/about for the about page #/contact for the contact page A very elegant way is to use ng-controller to run a single controller outside of the ng-view: <d
如果我有一个导航栏的项目引导 Home | About | Contact 如何在每个菜单项处于活动状态时为其设置活动类？ 也就是说，当角度路线class="active"时，我如何设置class="active" #/为家 #/about为关于页面 #/contact联系人页面 一个非常优雅的方法是使用ng-controller在ng-view之外运行一个控制器： <div class="collapse navbar-collapse" ng-controller="HeaderController"> <ul clas
I have a CSS3 animation at the top of my homepage that will start as soon as the page loads. The problem is if the user opens that page in a new tab but doesn't view it right away the animation will play even though they're not viewing that page. Is there a way to only get the animation to start only after the user has that views that page? Kind of like how if you open a youtube vide
我的主页顶部有一个CSS3动画，一旦页面加载就会启动。 问题是如果用户在新选项卡中打开该页面，但即使没有查看该页面，动画也不会立即查看。 有没有办法让动画只有在用户查看该页面后才能启动？ 有点像如果你打开另一个隐藏标签中的YouTube视频，它将不会自动播放，直到你打开该标签。 而且，如果您在新标签中打开笔，它将不会启动，直到您查看该标签为止 您需要使用可见性API：https://developer.mozilla.org/en-US/doc
I'm currently building an app (Electron) and i need to connect it with a c++ library. I have done most of the binding using the NodeJS c++ addons, but i'm missing an important part that is related with receiving the events generated by the c++ library on my Javascript code. void Event1(int64_t id) { ArrayBufferAllocator allocator; Isolate::CreateParams create_params; create_param
我目前正在构建一个应用程序（Electron），我需要将它与一个c ++库连接起来。 我已经完成了大部分使用NodeJS c ++插件的绑定，但是我错过了一个与接收由我的Javascript代码上的c ++库生成的事件有关的重要部分。 void Event1(int64_t id) { ArrayBufferAllocator allocator; Isolate::CreateParams create_params; create_params.array_buffer_allocator = &allocator; Isolate* isolate = Isolate::New(create_pa
Using opacity I made my whole div transparent but I want to mantain the font normal without opacity. I am unable to set a separate class or id to the content since it is dynamically created. I also cannot use the following: background: rgba(); {opacity : '0.3'} Any suggestions? For this you need to add a background image Transparent background. then on that image when you add the content
使用opacity我使整个div透明，但我希望保持字体正常，没有不透明。 我无法为内容设置单独的类或ID，因为它是动态创建的。 我也不能使用以下内容： background: rgba(); {opacity : '0.3'} 有什么建议么？ 为此，您需要添加背景图像透明背景。 然后在该图片上添加内容时会显示100％的不透明度。 看到这个不透明度，RGBA 使用rgba模式 P{ color:#fff; display:block; background: rgba(0,0,0,0.60); } DE
I'm trying to achieve the following effect: I have a div with a background-image and a semi-transparent white background-color on top of it which acts as a filter. Now, I want to add divs and some text which would basically "bypass" the filter so they are fully transparent. Is there a way to do this in css, or perhaps in Javascript or whatever? I am using Bootstrap and jQuery
我试图达到以下效果： 我有一个div背景图像和一个半透明的白色背景色，它充当过滤器。 现在，我想添加div和一些基本上“绕过”过滤器的文本，以便它们完全透明。 有没有办法做到这一点在CSS中，或者也许在Javascript或其他？ 我使用的是Bootstrap和jQuery，我也向任何可能帮助我的图书馆开放。 编辑： 这里是我刚刚做的一个小提琴：https：//jsfiddle.net/frbkLuoe/ HTML： <div class="container"> <di
I'm trying to make animated image noise, similar to the game Limbo, or Left4Dead. The noise would have to have levels of transparency, which takes .gifs out of the options. I could make a div with a .png sprite sheet, and animate through that, then repeat this small div all over the site, but that sounds costly. .apng would be the best choice, but that really isn't supported. The
我正在尝试制作动画图像噪音，类似于游戏Limbo或Left4Dead。 噪音将不得不具有透明度，从选项中取出.gif。 我可以制作一个带有.png精灵表的div，并通过它制作动画，然后在整个网站上重复这个小div，但这听起来代价很高。 .apng会是最好的选择，但是确实不支持。 我能想到的唯一的其他选项是使用javascript生成噪声客户端，但是这听起来像可能导致巨大的浏览器fps下降。 任何想法stackoverflow？ Limbo的提及带来了一
I need to create a CSS stylesheet class dynamically in JavaScript and assign it to some HTML elements like - div, table, span, tr, etc and to some controls like asp:Textbox, Dropdownlist and datalist. Is it possible? It would be nice with a sample. 虽然我不确定为什么要用JavaScript创建CSS类，但下面是一个选项： var style = document.createElement('style'); style.type = 'text/css'; style.innerHT
我需要在JavaScript中动态创建一个CSS样式表类，并将其分配给一些HTML元素，如div，table，span，tr等，以及一些控件，如asp：Textbox，Dropdownlist和datalist。 可能吗？ 样品会很好。 虽然我不确定为什么要用JavaScript创建CSS类，但下面是一个选项： var style = document.createElement('style'); style.type = 'text/css'; style.innerHTML = '.cssClass { color: #F00; }'; document.getElementsByTagName('head')[0]

This question already has an answer here: Stretch and scale a CSS image in the background - with CSS only 18 answers CSS rule background-image: url('file.svg'); To make your SVG scale you should use percentages for your measurements where possible. For instance if you want to make a gradient that fills the whole background: file.svg <?xml version="1.0" encoding="utf-8"?> <svg w
这个问题在这里已经有了答案： 在背景中拉伸和缩放CSS图像 - CSS只有18个答案 CSS规则 background-image: url('file.svg'); 为了使您的SVG缩放，您应尽可能使用百分比进行测量。 例如，如果你想制作一个填充整个背景的渐变： file.svg <?xml version="1.0" encoding="utf-8"?> <svg width="100%" height="100%"> <defs> <linearGradient id="grad" x1="0%" y1="0%" x2="0%" y2="100%
