50%{ So, each number shape has the same number of vertices and curves that animate correctly from one to the next. After recalculating all the values of our circle to follow the magic number which is the result of our beautiful formula, setting the percentage value is a much easier task to do. As the number is increased, say to 10%, the edge of the shape is pushed inward away from the elements side. Let's animate the circle chart by starting at the top and animating the the colored border down and to the right. I wrote a pure css drawing circle animation, but there's a little white space between the two half circles during the animation. Instead of ending the animation with the value defined in the CSS keyframe animation it begins with this value. @keyframes anim { Were going to dive right into clip-path in this article, specifically looking at how we can use it to create pretty complex animations. You'll notice that we rotate the circle -90 degrees. Every time I think something should be done with pure HTML or SVG and CSS, and it seems impossible to do it without JavaScript, I hate JavaScript. With Sass and Compass its a three-liner: Heres a Sass (.sass) mixin from Chris Eppstein for a more extensible text rotation mixin: Round logos have become quite big on the internet now. If your case only calls for one data point, you can remove the second inner of the SVG (and the CSS to go with it). Then set the counter to increment by the number of degrees needed to make it work. However, overdoing CSS animations will kill the vibe and be downright annoying. SEATS ARE RUNNING OUT! If it's using a matching preprocessor, use the appropriate URL Extension and we'll combine the code before preprocessing, so you can use the linked Pen as a true dependency. You can have total control over when you want to trigger the animation. Below is quick example; just hover on the circle to stop it. .circle-container:nth-child(3):after { } With Sass and Compass it's a three-liner: . The next keyframe shrinks the circle down to twenty percent. Similar to the previous 9-square animation, yet more methodical in how it brings each square into view and back out again. What would be good is a JavaScript plugin that does that too; you just set the height (radius) and it does it for you. waw! Taking advantage of the fact that this relationship between positive and negative space can be animated provides for interesting transition effects which is what were getting into in just a bit. You load jQuery and Lettering.js and then call this: This really only works well with monospaced fonts. Great work! } This gives the appearance of vertical slots wiping away their parts of the element. The spotlight transition is one animation with five keyframes using the circle shape. transform: translate(-50px) scale(0.6); The transformation attribute to display negative values, looks like the following: transform="rotate(-90 16.91549431 16.91549431) matrix(-1, 0, 0, 1, 33.83098862, 0)". We can break those out a little more to get a handle on the values for each shape and how changing them affects the movement. Its a little intimidating in the sense that it feels like math class because it requires working with geometric shapes, each with different values that draw certain shapes in certain ways. Is it possible to apply CSS to half of a character? Simple but smooth, this is another variation of the timeless loading dots animation. Its perhaps the most flexible of the bunch because we can draw custom, or even multiple, shapes with it. The polygon shape is a somewhat special case in terms of the properties it can animate. Individual classes .pulse-base, .pulse-circle and heart then use these animation with animation-iteration-count of infinite. Not the answer you're looking for? The inset and polygon shapes can be animated in a way to give the appearance of position-based movement. transform-origin: 400% 50%; Itll take me less time to whip up this logo in illustrator or photoshop than monkeying with the code for this.

Thanks. } The chevron transition is made of two animations, each with three keyframes. :). 100%{ The CSS used for this is ginormous just like the last one, so take a look at the CSS section of the CodePen demo starting with the .numbers-enter-active selector. They are, sorta. Very nice, thanks! Anyway, thanks for sharing, awesome demo ! The first, which is the leave animation, animates the top value of the inset shape from 0% to 100% providing the appearance of the entire square sliding downward out of view. There are ten keyframes in the animation and each keyframe resizes a circle while maintaining the state of any previously resized circle. /* display: none; */ The eight vertices in the polygon shape make a square with a vertex in the four corners and the midpoint of all four sides. Lettering.js can do that for you easily (jQuery and plugin dependency). transform: translate(0px); Want more inspiration? Ackermann Function without Recursion or Stack. Individual classes .pulse-base, .pulse-circle and heart then use these animation with animation-iteration-count of infinite. It was somehow clear to me that this has to be solved using plain CSS and SVG. Lets break those out just like we did before. The third keyframe then moves the vertices out of view to the right.

In this demo, we are going to learn about how to rotate an image continuously using the css animations. Then, the next keyframe changes the x and y coordinates of each vertex to be moved inward and near the next vertex in a clockwise fashion.
