Pure CSS to realize the battery charging animation effect of water ripples

This article will introduce to you how to skillfully use CSS to achieve the battery charging animation effect of water ripples. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

We know that the three major languages ​​​​that make up the front-end are: html, css and js, among which The most mysterious thing is css, why do you say that? Since the emergence of animation, transition and other attributes, it can be said that as long as you can’t think of it, there is nothing you can’t do ~

The previous article introduced a mobile phone charging animation effect, and I will continue it today. Compared with the previous article, The article is a bit simple, but for the sake of my girlfriend, I will write it here~

Special effects: Battery charging special effects, the overall special effects can be seen at the top

Prerequisite knowledge:

If you want to complete this special effect, you must know some prerequisite attributes. Let’s briefly introduce them:

animation , transform and filter will not be introduced in detail. Basically all animations will use these two properties. [Recommended learning: css video tutorial]

box-shadow

##box-shadow：Shadow

Usage: box-shadow: h-shadow v-shadow blur spread color inset;

• h-shadow: required, horizontal shadow position, negative values ​​allowed
• v-shadow: Required. The position of the vertical shadow. Negative values ​​allowed
• blur: blur distance
• spread: size of shadow
• color: Shadow color
• inset: Change the shadow from the outer shadow (at the start) to the inner shadow

border-radius

border-radius: Set rounded corners

You can set four values, which are the same as

margin and padding

That is, the order of the four values ​​​​of each radius is:

Upper left corner, Upper right corner, Lower right corner, Lower left corner .

If the lower left corner is omitted, the upper right corner is the same.
• If the lower right corner is omitted, the upper left corner is the same.
• If the upper right corner is omitted, the upper left corner is the same.

linear-gradient()

linear-gradient(): Gradient, used to create a gradient that represents two or more Picture of linear gradient of colors.

Usage:

background-image: linear-gradient(direction, color-stop1, color-stop2, ...);

• direction : Use the angle value to specify the direction (or angle) of the gradient, and specify the direction
• color...: What colors change to what colors in sequence

Container

We set up two divs, a container at the bottom of the seat, a small lid on it, mainly set the surrounding rounded corners through

border-radius, and add box -shadowAdd shadow to enhance the three-dimensional effect

##Charging effect

You can use positioning layout here and control it through

top

The position of the water. The larger the value of top, the lower the water. The smaller the value of top, the higher the water. We set the water level to 80% and pass

linear-gradient()

To set a gradient color of water:

Then the animation is very simple, you only need to control the

top

value It will cause the water to rise, like this

The points that need to be noted at this time are:

Our container at the top has rounded corners. , so when the animation reaches 100%, it should be the same as the rounded corners of the container.

• The water level is moving. In order to enhance the three-dimensional effect, you can set a shadow, which can have a progressive effect, so the color is best slightly slightly Make it darker, and the color is better to be closer
• Change color or pass:
filter: hue-rotate();
• This attribute controls

      .content{ //容器
          border-radius: 15px 15px 5px 5px;
          &::after{
              position: absolute;
              top: 80%;
              background: linear-gradient(to bottom, #7abcff 0%, #00BCD4 44%, #2196F3 100%);
              border-radius: 0px 0px 5px 5px;
              box-shadow: 0 14px 28px rgba(33, 150, 243, 0), 0 10px 10px rgba(9, 188, 215, 0.08);
              animation: change 10s linear infinite;
              filter: hue-rotate(90deg);
          }
      }
      @keyframes change {
            30% {
              box-shadow: 0 14px 28px rgba(0, 150, 136, 0.83), 0px 4px 10px rgba(8, 117, 134, 0.4);
            }
            50%{
              filter: hue-rotate(60deg);
            }
            80% {
              top: 20%;
              border-radius: 0 0 5px 5px;
              box-shadow: 0 14px 28px rgba(6, 136, 153, 0.2), 0 10px 10px rgba(12, 10, 112, 0.08);
            }
            100% {
                top: 0%;
                filter: hue-rotate(0deg);
                border-radius: 15px 15px 5px 5px;
                box-shadow: 0 14px 28px rgba(7, 93, 104, 0), 0 10px 10px rgba(31, 3, 68, 0.4);
            }
          }

Water ripple special effect

I believe everyone has seen this special effect. The idea is to set the background color at the approximate position above, cover it with the same background color,

and then The

translate

attribute is used, by converting the x, y values, and then by constantly rotating the angle. As for why the value is this value, I can’t figure it out. clear. . . Anyone who knows can leave a message in the comment area.<pre class="brush:js;toolbar:false;">p{ //复盖 border-radius: 45% 47% 44% 42%; transform: translate(-50%, 0); animation: move 10s linear infinite; } @keyframes move { 100% { transform: translate(-50%, -160px) rotate(720deg); } }</pre><p><img src="https://img.php.cn/upload/image/256/812/408/1650250971855508.gif" title="1650250971855508.gif" alt="Pure CSS to realize the battery charging animation effect of water ripples"></p> <p>此时，我们发现这个效果并不太真实，进行多覆盖两个，改变旋转值和<code>border-radius的值来设置水面不重叠，但又有差距的效果

p{
    &:nth-child(2){
      border-radius: 38% 46% 43% 47%;
      transform: translate(-50%, 0) rotate(-135deg);
    }
    &:nth-child(3){
      border-radius: 42% 46% 37% 40%;
      transform: translate(-50%, 0) rotate(135deg);
    }
}

此时的效果就非常真实了
