Provide options to pause, stop, or hide animations. How do I ensure my CSS animations are accessible?įocus on user control. Your pick when crafting CSS animation effects. Animations? They’re the full storyline, complex, controlled sequences that can loop, reverse, you name it. Think of transitions as a simple A to B journey – they need a trigger. What’s the difference between CSS transitions and animations? Your users click, touch, swipe – and your animations dance right along. Roll over a button, and watch that flourish. Cue the :hover or :focus to trigger animations. Can CSS animations respond to user interactions?Ībsolutely. Want a pro tip? Hardware acceleration, you’ll thank me later. Heavy lifting by other properties can bog things down. Not if you play it smart! Lean on properties like opacity and transform that don’t stress the browser. Are CSS animations tough on browser performance? Now, CSS animations are the brush strokes that add motion, paint on those first lines and witness your artwork move. So there you have it an elegant, practical and javascript-free CSS star ratings system that is easily customisable, uses only three stars as images and doesn’t have any unnecessary span’s or classes in the HTML.FAQs about CSS animations How do I start with CSS animations?ĭive in by learning the basics: animation-name, animation-duration, and Imagine giving life to a static picture that’s your HTML. The static position allows for the hover area to drop behind previous stars so you can move your cursor back again. We also create a negative left margin to create the illusion of the stars increasing and decreasing as the cursor hovers over them. We now need to define the hover and active states of our beautiful stars through adding a background image and changing its position. it allows you to hover over previously highlighted stars). We also apply relative positioning which results in the hover area of each star always being in front of the stars that are currently being hovered over (i.e. Then we define height and width (equal to a stars height and width) and remove the unwanted text from the page using text-indent. We make the list-items inline so they sit neatly next to each other. We also add an overflow property of hidden to accommodate some older browsers. The width and height of this is essential with the height being equal to the height of 1 x star and the width being equal to the width of 5 x stars. Now we define the height and width of the unordered list as well as the default star state (the grey star). The asterisks applies the formatting to all elements within the page but if you want the formatting to just target the star rating, first put the unordered list in a div with a class, then add that class before the asterisks in the CSS (i.e.classname *). In the CSS we firstly need to reset the margin, padding and list-style properties to remove unwanted formatting in our list. Then create a simple unordered list with 5 list items as displayed below. Save the image displayed below into the ‘images’ directory (as star.jpg) to prepare your star rating system’s different states. The trick to achieving this effect without an image defining every state lies in the use of positioning and negative margins generally unpredictable properties unless used cautiously we will come to these later.įirstly prepare your external/internal CSS and HTML documents with an ‘images’ folder relative to your documents. Below I have an example of a new and elegant approach that uses some CSS trickery and a single image defining the three states of static, hover and active. I have ploughed through several pure CSS star rating systems, only to find that many use either unnecessarily large images (defining every state) or bloated mark-up in both HTML and CSS.
