It’s the New Year~ It’s the New Year~ It’s the New Year~

Say goodbye to the old and welcome the New Year, it’s the Spring Festival with lanterns and colorful decorations~

The golden rooster dances to send Blessings are coming in the new year~

The first few lyrics of the article suddenly seem festive. No, our lanterns look like this.

animation attribute

Drawing a lantern We definitely cannot draw a static lantern. Let’s first review the animation attribute in CSS. , which is a shorthand attribute consisting of animation-name, animation-duration, animation-timing-function, animation-delay , animation-iteration-count, animation-direction, animation-fill-mode and animation-play-state attributes. We won’t explain it here. You can learn more about it in MDN.

Let’s first take a look at the following example:

animation: swing 3s infinite ease-in-out;

In the above example, an animation sequence named swing is used. The animation sequence passes @ keyframes is created, the execution time is 3s, the animation is executed in a loop, and the last ease-in-out indicates the rhythm of animation execution.

Implementation Idea

• Add border-radius to a rectangle to form the shape of a lantern.

• Add ::before and ::after to the rectangle to form the top and head of the lantern

• Draw a lantern line.

• Add two thinner rectangles inside the rectangle, and form the lines of the lantern by adding border-radius.

• Set the animation effect of the lantern

• Add the style of the lamp spike

Next we will Implemented in steps.

Drawing the shape of the lantern

First we define the HTML structure, the code is as follows:

<!-- 灯笼容器 -->
<div class="lantern-con">
  <!-- 提着灯笼的线 -->
  <div class="lantern-line"></div>
  <!-- 灯笼主要区域 -->
  <div class="lantern-light">
  </div>
</div>

Then we draw an ellipse, and then pass ::before and ::after, draw the upper and lower lantern covers, the CSS is as follows:

/* 灯笼容器 */
.lantern-con {
  position: fixed;
  left: 160px;
}

/* 灯笼中间红色区域 */
.lantern-light {
  position: relative;
  width: 120px;
  height: 90px;
  background-color: red;
  margin: 30px;
  border-radius: 50%;
  box-shadow: -5px 5px 50px 4px #fa6c00;
  /* 设置旋转点 */
  transform-origin: top center;
  animation: swing 3s infinite ease-in-out;
}

/* 灯笼顶部和底部的样式 */
.lantern-light::before,
.lantern-light::after {
  content: '';
  position: absolute;
  border: 1px solid #dc8f03;
  width: 60px;
  height: 12px;
  /* 背景渐变 */
  background: linear-gradient(
    to right,
    #dc8f03,
    #ffa500,
    #dc8f03,
    #ffa500,
    #dc8f03
  );
  left: 30px;
}

/* 顶部位置 */
.lantern-light::before {
  top: -7px;
  border-top-left-radius: 5px;
  border-top-right-radius: 5px;
}

/* 底部位置 */
.lantern-light::after {
  bottom: -7px;
  border-bottom-left-radius: 5px;
  border-bottom-right-radius: 5px;
}

/* 提着灯笼的线的样式 */
.lantern-line {
  width: 2px;
  height: 50px;
  background-color: #dc8f03;
  position: absolute;
  left: 88px;
}
/* 灯笼的动画效果 */
@keyframes swing {
  0% {
    transform: rotate(-6deg);
  }

  50% {
    transform: rotate(6deg);
  }

  100% {
    transform: rotate(-6deg);
  }
}

Now a relatively basic lantern shape has been implemented, the effect is as follows:

Internal lines of the lantern

The internal lines of the lantern are realized through two rectangles. Set it to an ellipse through the border-radius property, and then draw the edges to present the lantern lines. .

<div class="lantern-light">
  <!-- 灯笼中间的线条 -->
  <div class="lantern-circle">
    <div class="lantern-rect">
      <!-- 灯笼中间的文字内容 -->
      <div class="lantern-text">灯笼</div>
    </div>
  </div>
</div>

The corresponding CSS is as follows:

/* 灯笼中间的线条 */
.lantern-circle,
.lantern-rect {
  height: 90px;
  border-radius: 50%;
  border: 2px solid #dc8f03;
  background-color: rgba(216, 0, 15, 0.1);
}

/* 外层 */
.lantern-circle {
  width: 100px;
  margin: 12px 8px 8px 10px;
}

/* 内层 */
.lantern-rect {
  margin: -2px 8px 8px 26px;
  width: 45px;
}

/* 文字样式 */
.lantern-text {
  font-size: 28px;
  font-weight: bold;
  text-align: center;
  color: #dc8f03;
  margin-top: 4px;
}

The effect is as follows:

Lantern Spike

Now let’s draw it Lantern spike, this thing is relatively simple. The most important thing is to add an animation effect. Its HTML structure is as follows:

<!-- 灯笼主要区域 -->
<div class="lantern-light">
  <!-- more code -->
  <!-- 灯笼穗 -->
  <div class="lantern-tassel-top">
    <div class="lantern-tassel-middle"></div>
    <div class="lantern-tassel-bottom"></div>
  </div>
</div>

CSS is as follows:

/* 灯穗 */
.lantern-tassel-top {
  width: 5px;
  height: 20px;
  background-color: #ffa500;
  border-radius: 0 0 5px 5px;
  position: relative;
  margin: -5px 0 0 59px;
  /* 让灯穗也有一个动画效果 */
  animation: swing 3s infinite ease-in-out;
}

.lantern-tassel-middle,
.lantern-tassel-bottom {
  position: absolute;
  width: 10px;
  left: -2px;
}

.lantern-tassel-middle {
  border-radius: 50%;
  top: 14px;
  height: 10px;
  background-color: #dc8f03;
  z-index: 2;
}

.lantern-tassel-bottom {
  background-color: #ffa500;
  border-bottom-left-radius: 5px;
  height: 35px;
  top: 18px;
  z-index: 1;
}

At this point we have finished drawing this lantern.
