You signed in with another tab or window. Lets change the background configuration by replacing the zig-zag underline with a wavy underline instead: Another collection of hover effects! We first have a background-position transition followed by a background-size one. Notice how this.reset() is modifying the transform property. The exact effects depend on your default settings and desires. Lets introduce a custom property to avoid the repetition of background-size: We are not defining --p initially, so the fallback value (0% in our case) will be used. x) * speedX; pos. Go experiment! We are going to learn how to combine all of these so we are left with nicely optimized code! I recommend reading up on the almanac entries for perspective and transform before we get started. Lets guzzle directly from the React Documentation: If this component has been mounted into the DOM, [findDOMNode] returns the corresponding native browser DOM element. What a time to be alive. Again, were back to only three declarations for a pretty cool hover effect! Direct will move the element in the same direction as the mouse movement. Lets start with the first effect which is the reproduction of the one detailed by Geoff in his article. We are doing that every time the mouse moves via the onMouseMove event. Intuitively, we may think that each gradient needs to take up half of the elements width but thats actually not enough. The bottom line is React manages these events without us requiring to start and stop the handlers manually. Continuous Scrolling Background on Sticky Header. Transition and transform manipulate from one state to another, while animation paired with @keyframes rules can set multiple style rules at various points throughout the animation duration. I can code in HTML, CSS, Javascript, jQuery for the frontend, and in PHP, SQL for the backend. - Created at July 11, 2013. Awesome. 02. Since we are making a reusable component, we need some default settings. You can see that variable as a switch that update all our values at once on hover.

I think you will get a better understanding of how the isTimeToUpdate method if you comment these CSS lines: With an updateRate of 1 or 0, your inner div will be updated everytime your mouse moves (at each pixel)! And even though they are different effects, they all take the same approach of using CSS background properties, custom properties, and calc(). With background-size, we can omit the height because gradients are full height by default. Can we still optimize the code and use only one custom property? Right after that, we change the color and the background-color. This is how you can solve for unknowns. I figured Id make a little tutorial explaining how each part works so you could easily reproduce it or extend it. Jake Albaugh has reproduced a scroll-jacking experience with changing areas.

Passionate about aeronautics and model aircraft. Lets take a look at a step-by-step illustration to understand what is happening. After that, we slide them to the bottom to update their position. 01. That is the central reason we dont want everybody to start linking directly to DOM Nodes. No one likes to spend 700 hours configuring their app before they start developing it, not that theres anything wrong with that. As we detail, I will take opportunities to explain why we use certain techniques. We setup the Tilt component to accept configuration settings that we can change them on the fly, even automatically as React updates state! It would be too long to detail each one but with what we have learned so far you can easily understand the code. We still have three declarations and one custom property, but a different effect. The first background gradient is clipped to the text (thanks to the text value) to set the color on hover, while the second background gradient creates the bottom underline (thanks to the padding-box value). 9,715 posts. Here the mouse leaves a trace that closely resembles a stroke of oil painting. You will find your typical stuff available on e such as e.target.value (if we had an input field). To review, open the file in an editor that reveals hidden Unicode characters. Thats true, nice catch. Each time you reload the page the color changes, yet the effect remains the same. Cheers! Top learnings on how to get to the mid/senior level faster as a JavaScript developer by Dragos Nedelcu. Maybe it's trendy, maybe it's Maybelline; Surely, it's rad . On mouse out, we will reset it. We talked about this.updateElementPosition(). The left and right values can be changed to 0 0 and 100% 0, respectively; and since our gradient is already full height by default, we can get by using 0 and 100%. Lastly, we apply the fading to color and a background-color to create the mouse-out part of the animation. Take a look at Tim Holman's codepen. Forks welcome! Then its defined again for background-position which is similar to defining it for background-size, then background-position. We need a more complex transition for this effect. DEV Community A constructive and inclusive social network for software developers. You can play with movement, timeout and ease effects to see what works best for you. What's the difference between a power rail and a signal line? Or, you could move an actual element instead (rather than the background-position). Web Design and Development Online Magazine. We also need to add a wrapper div around the photo so our component can become reusable: Run this code and press F12 to open the Dev Tools Console. First, lets start with a simple background-size transition: We are animating the size of a linear gradient from 0 100% to 100% 100%. I kept all the mask configurations and changed the background to create a different shape. We are essentially cutting out the middleman because we dont need him. The first thing we'll need to do is create a new pen and change some of the default settings for the CSS editor in CodePen. After looking at four similar hover effects, you should be able to get the final optimization down to a single custom property. I was afraid the site is taking a drastic change in focus. See the Pen Move a background with mouse by Chris Coyier (@chriscoyier) on CodePen. Ana Tudor shared a great article explaining how to create DRY switching where one custom property can update multiple properties. Using a pseudo property with an absolute or fixed position can handily avoid this problem and keep the animations running at buttery-smooth 60fps. These are arbitrary numbers. Imagine that the green and red parts are the visible parts of the element while everything else is transparent. This is another codepen in our list that owes its beauty to a range of bright balls of various sizes. Feel free to invent your own. Everything else is straight up copied from the work we did in the first article of this series. Effects. The mask is composed of two gradients. Cool! var speedX = 0.1; var speedY = 0.3; // pos.

Setting "checked" for a checkbox with jQuery. With the technique, you can supply each section with a different pop-up information box. We made four super cool hover effects! We first transform our gradient to use the color only once: The syntax might look a bit strange, but we are telling the browser that one color is applied to two color stops, and thats enough to define a gradient in CSS. to right so the backgrounds size will increase from the right side. Lets move on to another hover effect using background-clip: Youre probably thinking this one looks super easy compared to what weve just covered and you are right, theres nothing fancy here. Objects in the foreground appear to move faster than the ones in the background, which barely move at all. These are crazy and uncommon hover effects and I realize they are too much in most situations. In that example, I use two different gradients and two values with background-clip. Before we move to the next hover effect, I want to highlight something important that you have probably noticed. For this, we can use complex animations, or others simpler as parallaxes. Would this need a reasonable debounce? To learn more, see our tips on writing great answers. Here is what you can do to flag clementgaudiniere: clementgaudiniere consistently posts content that violates DEV Community's Still, its a great idea that shows how to combine gradients with blend modes to create even cooler hover effects. Recall from math class that opposing corners add up to 180 degress. Minimising the environmental effects of my dyson brain. We have a couple extra Class Properties now because they are holding the state. Imagine this kind of stuff while you are not only looking at those logs but also working with DOM elements in general: Imagine animating DOM elements. to right so the background's size will increase from the right side. . We are going to incrementally update your Class Methods. The unit-less zero may work when the custom property is alone, but will fail inside calc() where we need to explicitly define the unit. With more than 70 pure CSS effects in 5 different styles, this dependency-free WordPress plugin offers an intuitive shortcode builder to add some icing on the cake to your blog or website. Increase the size from the right on mouse hover. Tilda Web Animation Tutorial: Learn how to create a parallax effect on mouse move. What is the different? Nothing complex so far.

Cool Hover Effects That Use Background Properties, Cool Hover Effects That Use CSS TextShadow, Cool Hover Effects That Use Background Clipping, Masks, and 3D (. The playground reacts on mouse movements. When you move the mouse the text at the various layers follows the mouse pointer at a different speed which creates an illusion of 3D effect for the text. Unflagging clementgaudiniere will restore default visibility to their posts. The span must be in position: absolute;, and have a border-radius of 100%, in order to create circular blocks. The returned value is a DOMRect object which is the union of the rectangles returned by getClientRects() for the element, i.e., the CSS border-boxes associated with the element. Lets start our optimizations. Right after that, we change the color and the background-color. Its more the final step of code optimization. If you arent using CRA, you should consider it because it brings an emphasis on zero-config or at least minimal config. Thanks for keeping DEV Community safe. Some years ago I saw PC Gamer do something similar. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Next up is the mouse object. The reason being background properties cause repaints, and that gets expensive fast. Then, when the mouse cursor leaves the link, the transition plays in reverse . If we were delegating the handling up to a parent or calling back to some other location, we should use on. The result is the smallest rectangle which contains the entire element, with read-only left, top, right, bottom, x, y, width, and height properties describing the overall border-box in pixels. The concept is elegant and at the same time impressive. We'll change the CSS Preprocessor to SCSS and turn on Normalize and Autoprefixer. Its like when a male human tries to contact a female human, and her brother steps in between to efficiently handle the event.

The browser is doing what we call repaints and reflows. You are probably surprised how small the code is, but you will see how we got there. I am super serious about that. getBoundingClientRect gets the X and Y coordinates and the width and height of a DOM element. I want you to internalize and recruit every neuron. join me at the bottom of this code block. It should be like: $ (".box1").css ( { "background-position": x/2 + "20px ," + y/2 + "20px" }); Also you'd need to callibrate your x and y to distances from left of box1 and top box1 repectively. This solution transforms a mouse cursor in a moving orbit of large particles. Then we set each span one by one, by defining a color, a z-index, and its position. However, this technique is likely something youd want to avoid using in production, as Firefox is known to have a lot of reported bugs related to background-clip. The first thing we do is to define our variables: Then we create a transparent border with widths that use the above variables: The top and right sides of the element both need to equal the --b value while the bottom and left sides need to equal to the sum of --b and --d (which is the --_s variable).
