Dropdown slide down animation
Slide down animation css codepenIn android, Slide Up and Slide Down animations are used to change the appearance and behavior of the objects over a particular interval of time. The Slide Up and Slide Down animations will provide a better look and feel for our applications. To create an animation effect to the objects in our android application, we need to follow below steps. Once we are done with creation of required animation XML files, we need to load those animation files using different properties. In android, we can perform animations by using AnimationUtils component methods such as loadAnimation. Following is the code snippet of loading and starting an animation using loadAnimation and startAnimation methods. If you observe above code snippet, we are adding an animation to the image using loadAnimation method. The second parameter in loadAnimation method is the name of our animation xml file. Here we used another method startAnimation to apply the defined animation to imageview object. Now we will see how to implement slide up and slide down animations for imageview on button click in android applications with examples. Following is the example of implementing a slide up and slide down animations to slide an image up or down on button click in android applications. Create a new android application using android studio and give names as SlideUpDownExample. In case if you are not aware of creating an app in android studio check this article Android Hello World App. In case anim folder not exists in res directory, create a new one. Now open your main activity file MainActivity. AppCompatActivity; import android. Bundle; import android. View; import android. Animation; import android. AnimationUtils; import android. Button; import android. If you observe above code, we are adding an animation to the image using loadAnimation method used startAnimation method to apply the defined animation to imageview object. If you observe the above result, whenever we are clicking on Slide Up or Slide Down buttons, the image size varies based on our functionality. This is how we can implement slide up and slide down animations for imageview in android applications based on our requirements.
Slide down animation jqueryComment 5. Sometimes something seems like it should be really easy, but it turns out to be extremely difficult. The case we'll be checking out today is creating a slide-down animation using purely CSS. What could be so hard about that, right? If you're not sure what I mean by a "slide-down animation," check out the slideDown method from jQuery. This function will take a hidden element and make it visible by increasing the element's height from 0 to whatever the height of the element should be. That shouldn't be too hard, right? Let's take a look at some quick ideas of how you might expect to be able to do this easily. If you simply go by what I said earlier, you'd just set the height to 0, and then to expand it, set the height to the number that shows the whole element with a transition as well; this is assumed for all of them, otherwise it won't be an animation. Something like this:. You'll need to go back in the frame's history or press "Rerun" to toggle them off. Note that it works perfectly! Problem solved right? Yes and no. This works perfectly if you know the height of the element, but what if you don't know the height? We'll need a generic animation that will work no matter what height the element is. This is especially true on a responsive site, where the height can change depending on screen size. In this case, the seemingly obvious solutions is to just set the height to auto in the expanded version's styles. Oh how I wish this worked. This would make everything so much easier, but sadly transitions only work on numeric values. Sure, auto does eventually compute to a numeric value, but that message doesn't seem to get to transitionso it just pops right open instead of doing a nice animation. So what can we do? How about CSS Transforms? We'll set scaleY to zero and then set it to one when it should be expanded. Will that work? When you use a transform, it doesn't actually change the amount of space it takes up, so there are big gaps between the links instead of making that area appear at the same time the element starts expanding. So this isn't working either. So how about we take a look at the method that I discovered. The answer is to set everything that can affect height e. You need to be careful with this because there are lots of things that can affect height. For example, if there were multiple paragraphs of text inside the element, you'd need to adjust the margins between those paragraphs. If you have any images, you'll need to make sure the height and vertical margins around it are also set to 0. This works better than just using height since you're far more likely to know the values of each of these properties than you are to know the height of the expandable element. Note : I also set the text color to toggle between transparent and black to give it a fading look. This is not necessary, but looks a little nicer.

Css keyframes slide downPure CSS is more than enough to create incredible web animations. These can range from sliders to carousels and even dropdown navigation menus. But the trickiest part about CSS animation is learning how it all works. The nav submenu links will slide in from the right-hand side of the screen and disappear when hidden. Live Demo — Download Source Code. This just makes the design a lot easier to manage without re-writing lines of code. Each list item contains a link and the dropdown items contain a secondary UL element. The internal nav element is similar, but can be setup with a fixed width to center the content. So if your layout never goes beyond px you can set max-width: px to the nav element. Lastly I have a div with the class. Moving over to my styles. This code uses natural CSS animation with keyframes and lots of pseudo-classes where appropriate. This allows the full menu to stay fixed as you scroll down the page. The next block of code defines how the menu should behave. Every first-level list item has a line height of 64px. This is my chosen height for the menu itself — obviously you can adjust as needed. Since we have these elements positioned we can use the z-index property. This forces all sub-menu list items to stay on top of the unordered list so links appear on top of the blue background. Keep in mind there are two subtle animations: first the sub-menu drops down into view, then the sub-links slide into view from the right side of the page. Each animation is later defined using keyframes, but you can see they have individual names applied to the appropriate elements. One more advanced feature is the use of :before and :after pseudo-classes on the sub-menu list. One appears before the links, the other appears after them. So this little trick forces a fullsize background onto the element. It also allows the user to hover their mouse across the entire blue bar without auto-closing the submenu. Another neat CSS effect is the creation of arrow icons. These use the border transformation hack in CSS to create a border which gets cut off by positioning. And finally the keyframe rule is used to define the nav dropdown and link slide effects. You can adjust these values to make the navbar larger, or to animate the links into different locations. Also try adjusting the animation properties found earlier in the code to increase or decrease the animation speed. I hope this tutorial offers an interesting glimpse into CSS development. With modern CSS animations you can build practically anything with a high level of accuracy and browser support. Feel free to download a copy of my source code and play around in your own projects.
