海外TECH	DEV Community	Reflection! Cool Effects with -webkit-box-reflect	https://dev.to/chokcoco/reflection-cool-effects-with-webkit-box-reflect-dpl	Reflection Cool Effects with webkit box reflect webkit box reflect is a very interesting property that gives CSS the ability to act like a mirror reflecting what our elements were originally drawn on The last time I wrote it its compatibility was very very bleak but today although it is still a Non standard syntax the compatibility has been greatly improved and using it we can achieve a lot of interesting Effect As of its compatibility has reached take a look at CANIUSE webkit box reflect What is webkit box reflectThe syntax of webkit box reflect is very simple the most basic usage looks like this div webkit box reflect below Among them below can be below above left right means bottom top left right that is there are directions to choose from Suppose we have the following image lt div gt lt div gt div background image url Add webkit box reflect right which is the reflection on the right div background image url webkit box reflect right The effect is as follows generating a mirrored element to the right of an element Set the reflection distanceAfter the direction you can also follow a specific numerical value to indicate the distance between the reflection and the original element div background image url webkit box reflect right px After adding px the reflection will be separated from the original element by px Set the gradient of the reflectionThere is also a very important function that is behind the azimuth you can also set a gradient value Using this gradient value you can achieve a blurring effect of the reflection which is very important div background image url webkit box reflect below px linear gradient transparent rgba Look at the effect after the virtual and real changes it is more like a reflection In fact the gradient here is to add a MASK attribute to the reflected image In the transparent part of the MASK attribute the image will become transparent while the solid color part will remain the original image CodePen Demo webkit box reflect Demo Use webkit box reflect to achieve some interesting animationsAfter mastering the basic syntax we can use it to achieve some interesting dynamic effects which are briefly listed below I ve found this property to be especially useful in some dark style pages It can make a lot of dynamic effects look much taller personal aesthetic Using webkit box reflect in buttonsWith some buttons with dynamic border animation it can create a very sci fi effect If you are interested you can poke the source code to understand CodePen demo webkit box reflect Neon Button Hover Effect Use webkit box reflect in the Text EffectsIn a darker setting the use of webkit box reflect makes the whole effect much more advanced CodePen demo Font amp webkit box reflect Use webkit box reflect in D EffectsNext we can even apply webkit box reflect to the D effect to create a completely different viewing experience Let s add a reflection effect to a D photo wall CodePen demo DView amp webkit box reflect Use webkit box reflect to create artistic patternsInteresting CSS art here it is again In this article by Mr Yuan Chuan Chinese Window Lattice And CSS it introduces the use of webkit box reflect generates such an idea of ​​​​cutting art Since webkit box reflect can generate reflections we can use it to perform continuous nesting of dolls layer by layer then we only need to generate a basic element and we can use reflections to produce various effects Suppose we have the following structure lt div class g wrap gt lt div class g wrap gt lt div class g wrap gt lt div class g wrap gt lt div gt lt div gt lt div gt lt div gt We just need to implement a graph for g wrap for example g wrap background radial gradient circle at transparent transparent transparent radial gradient circle at transparent transparent transparent Then there are layers of nesting first adding a layer of reflection to wrap via webkit box reflect g wrap webkit box reflect right px we can get Continue nesting and add a layer of reflection to the g wrap g wrap webkit box reflect right px g wrap webkit box reflect below px Go ahead and add a reflection webkit box reflect to g wrap g wrap webkit box reflect right px g wrap webkit box reflect below px g wrap webkit box reflect left px Finally add a webkit box reflect to g wrap g wrap webkit box reflect right px g wrap webkit box reflect below px g wrap webkit box reflect left px g wrap webkit box reflect above px We can get a graphic obtained by layers of reflection In this way through different basic graphics we can use our imagination to generate a variety of paper cut symmetrical graphics The complete code can be found here CodePen Demo webkit box reflect artist FinallyMore wonderful CSS technical articles are summarized in my Github iCSS And maybe you will love my CodePen which has a large number of amazing CSS effects	2022-08-07 05:17:14
海外TECH	DEV Community	Bringing perspective to CSS	https://dev.to/dailydevtips1/bringing-perspective-to-css-1ffd	Bringing perspective to CSSThe other day I started exploring D in CSS and began with a dice The dice is excellent in D However it has no perspective so it s still D in D Let s fix that and bring some perspective to D If we stop the rotation on the dice and look at it from the front you can see the overlap but all sides are equally big This is a bit weird as the back panel should be smaller as it sits more to the back CSS perspectiveThat s precisely where the perspective style can come into play Let s apply the following style to the body tag body perspective px A crazy difference already right You can play around with the value The lower you go the more intense the D becomes We also get perspective origin which can define from which angle you are looking at an object The default value is and we can use values we know from position to set it body perspective origin left This will set the perspective to the left As you can see this becomes a bit weird and you can make the perspective a bit bigger to get the correct display Playing with perspective can give your D css that next level feeling Feel free to play around with the adjusted dice Thank you for reading and let s connect Thank you for reading my blog Feel free to subscribe to my email newsletter and connect on Facebook or Twitter	2022-08-07 05:00:46
