There may be already a jQuery plugin which can achieve this, but I can't find one to do exactly what I'm after. If there is, just point me to the tutorial, thanks. My problem I have is that I have very long page content, and my sidebar is not visible when you are scrolled near the bottom of the page. So I would like to make my #sidebar div to stick to the top and bottom of my browser window as you scroll up and down the page. My sidebar height is longer than your typical screen resolution, so I need the bottom of sidebar to sticky to the bottom of the browser window as well as the top of the

android -------- LiveDataBus的使用

阅读更多关于 android -------- LiveDataBus的使用

LiveData是17年GoogleIO大会上提出来的一个新技术。相对于通信总线类型的框架EventBus和RxBus来说，它更简单，更简洁、更解耦。 LiveEventBus是一款Android消息总线，基于LiveData，具有生命周期感知能力，支持Sticky，支持AndroidX，支持跨进程，支持跨APP LiveDataBus优点 LiveDataBus的实现及其简单相对EventBus复杂的实现，LiveDataBus只需要一个类就可以实现 LiveDataBus可以减小APK包的大小 LiveDataBus只依赖Android官方组件LiveData，本身实现只一个类。EventBus 57Kb、RxJava 2.2M LiveDataBus 依赖方支持更好 LiveDataBus只依赖Android官方组件LiveData，相比RxBus依赖的RxJava和RxAndroid，依赖方支持更好 LiveDataBus具有生命周期感知 LiveDataBus具有生命周期感知，在Android系统中使用调用者不需要调用反注册，相比EventBus和RxBus使用更为方便，并且没有内存泄漏风险。 LiveEventBus的特点生命周期感知，消息随时订阅，自动取消订阅支持Sticky粘性消息支持AndroidX 支持跨进程通信支持跨APP通信

Sticky sidebar: stick to bottom when scrolling down, top when scrolling up

问题 I have been looking for some time now for a solution to my sticky sidebar problem. I have a specific idea of how I would like it to act; effectively, I would like it to stick to the bottom as you scroll down, and then as soon as you scroll back up I would like it to stick to the top, in a fluid motion (no jumping). I am unable to find an example of what I am trying to achieve, so I have created an image that I hope will illustrate the point clearer: Sidebar sits under the header. As you

CSS: 'position: sticky' not working when 'height' is defined

I am building a landing page where the user first sees a main area with a footer underneath it. Scrolling further down reveals that the footer is a sticky header, and I aim to use pure CSS to achieve this. To obtain the fullscreen appearance of the main content and the footer I set the height property to two different values: 92% and 8% (using vh also doesn't work). No matter the height I specify in my CSS (different units and all), my footer div is not sticking. As soon as I remove the height property it works as intended. Here is a screenshot of my page before removing the height properties:

问题 I do NOT want a FIXED footer, I need a STICKY footer. My sticky footer worked fine at first but when the content is at a certain height, there is a margin between the footer and bottom of the page. Try messing with the browser height and content div height, and you should see where the problem is. It leaves an awkward margin between the footer and the bottom of the page. Thank you in advance.
