Cleverly use CSS3's webkit-box-reflect to achieve various dynamic effects

In an article a long time ago, I talked about the property -webkit-box-reflect -- Let's talk about CSS inheritance from reflection

-webkit-box-reflect is a very interesting property, which gives CSS the ability to reflect the content originally drawn by our element like a mirror.

The last time I wrote it, its compatibility was very, very poor. But today, although it is still a non-standard syntax, its compatibility has improved greatly, and using it, we can achieve many interesting effects.

As of 2021-02-19, its compatibility has reached 91.02%, take a look at CANIUSE -webkit-box-reflect:

Next, enter the main text.

-webkit-box-reflect basic usage

The syntax of -webkit-box-reflect is very simple. The most basic usage is like this:

div {
    -webkit-box-reflect: below;
}

Among them, below can be below | above | left | right, representing below, above, left and right, that is, there are 4 directions to choose from.

Suppose we have the following picture:

<div></div>

div {
    background-image: url('https://images.pokemontcg.io/xy2/12_hires.png');
} 

Add -webkit-box-reflect: right , which is the reflection on the right:

div {
    background-image: url('https://images.pokemontcg.io/xy2/12_hires.png');
    -webkit-box-reflect: right;
}

The effect is as follows, generating a mirror image element on the right side of an element:

Set the reflection distance

After the direction, you can also add a specific numerical value to indicate the distance between the reflection and the original element.

div {
    background-image: url('https://images.pokemontcg.io/xy2/12_hires.png');
    -webkit-box-reflect: right 10px;
}

After adding 10px , there will be a 10px gap between the reflection and the original element:

Set reflection reality

There is another very important function, which is that you can set a gradient value behind the direction. By using this gradient value, you can achieve a blurring effect of the reflection, which is very important.

div {
    background-image: url('https://images.pokemontcg.io/xy2/12_hires.png');
    -webkit-box-reflect: below 2px linear-gradient(transparent, rgba(0, 0, 0, .5));
}

Look at the effect. After the virtual and real changes, it looks more like a reflection.

In fact, the gradient here is to add a MASK attribute to the reflected image. The transparent part of the MASK attribute will make the image transparent, while the solid color part will remain the original image.

Use -webkit-box-reflect to achieve some interesting animation effects

After mastering the basic grammar, we can use it to achieve some interesting animation effects, which are briefly listed below.

I found that this attribute is particularly suitable for use in some dark style pages. It can make many dynamic effects look much more advanced. (Personal aesthetic)

Using -webkit-box-reflect in buttons

Combined with some buttons with dynamic border animations, it can create a very sci-fi effect:

Using -webkit-box-reflect in text

In the dark title text, the use of -webkit-box-reflect instantly makes it look more elegant.

Using -webkit-box-reflect in 3D

Hey, next, we can even apply -webkit-box-reflect to the 3D effect, which will give us a completely different viewing experience.

We add a reflection effect to a 3D photo wall:

Creating artistic patterns with -webkit-box-reflect

Interesting CSS art, here it comes again.

In this article by Professor Yuan Chuan - Chinese Window Lattice And CSS, the idea of ​​using -webkit-box-reflect to generate paper-cutting art is introduced.

Since -webkit-box-reflect can generate reflections, we can use it to continuously nest 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:

<div class="g-wrap1">
    <div class="g-wrap2">
        <div class="g-wrap3">
            <div class="g-wrap4"></div>
        </div>
    </div>
</div>

We just need to implement a graphic for .g-wrap4 , like this:

.g-wrap4 {
    background: 
        radial-gradient(circle at 0 0, #000 30%, transparent 30%, transparent 40%, #000 40%, #000 50%, transparent 50%),
        radial-gradient(circle at 100% 100%, #000 10%, transparent 10%, transparent 30%, #000 30%, #000 40%, transparent 40%);
} 

Then there are 4 layers of nesting dolls. First, add a layer of reflection -webkit-box-reflect to .g-wrap4 :

.g-wrap4 {
    -webkit-box-reflect: right 0px;
}

get:

Continue nesting dolls and add a layer of reflection -webkit-box-reflect to .g-wrap3 :

.g-wrap4 {
    -webkit-box-reflect: right 0px;
}
.g-wrap3 {
    -webkit-box-reflect: below 0px;
} 

Continue, add a layer of reflection -webkit-box-reflect to .g-wrap2 :

.g-wrap4 {
    -webkit-box-reflect: right 0px;
}
.g-wrap3 {
    -webkit-box-reflect: below 0px;
}
.g-wrap2 {
    -webkit-box-reflect: left 0px;
} 

Finally, add a layer of reflection -webkit-box-reflect to .g-wrap1 :

.g-wrap4 {
    -webkit-box-reflect: right 0px;
}
.g-wrap3 {
    -webkit-box-reflect: below 0px;
}
.g-wrap2 {
    -webkit-box-reflect: left 0px;
}
.g-wrap1 {
    -webkit-box-reflect: above 0px;
}

You can get a figure obtained through 4 layers of reflection:

In this way, through different basic graphics and using our imagination, we can generate a variety of paper-cut symmetrical graphics:
