Create a cute frog expression using html

First feel all the emoticons:

Before starting, let’s have a knowledge point: Flex elastic layout

• We generally use the float method for horizontal three-column layout, and display each floating block in the same line. This method will result in the element not having the original height attribute, and clearing the float is required to solve the space occupation problem. It is very inconvenient for those special layouts. For example, vertical centering is not easy to achieve.

• In 2009, W3C proposed a new solution - Flex layout, which can realize various page layouts simply, completely and responsively. Currently, it is supported by almost all browsers, which means that it is safe to use this feature now. Check out the blog for basic syntax: Flex Layout Tutorial: Grammar

• In addition, you must have a certain understanding of pseudo-elements in css: before, after

• Finally, if you want to make the expression move, the most important thing is to use the animation attribute.

Overall layout

• We first lay out the overall seat so that each expression can be displayed intuitively in each position, because each The emoticons almost occupy a square space, so we display each frog emoticon horizontally on the page, using flex layout here.

  <div class="container"><!--所有表情的存放容器，flex布局，所有子项目水平显示，自动换行，水平居中显示，竖直方向从顶部开始--><div class="emoji-container">   <!--存放青蛙表情的大容器，控制大小间距之类的属性--><div class="icon">       <!--存放每一个青蛙表情的容器，控制每一个表情自己的位置和特征--><div class="frog" id="frog-n"></div></div></div></div>
  body {background-color: #F1FFE6;}
  .container {width: 950px;margin: 70px auto 0px auto;text-align: center;}
  .container .emoji-container {
  /*flex弹性布局，多用于左右并排布局，跟float的作用类似，不用清除浮动*/
  display: -webkit-box;   
  display: -ms-flexbox;
  display: flex;
  /*justify-content属性定义了项目在主轴上的对齐方式。center就是在x轴上居中显示*/
  -ms-grid-column-align: center;
      justify-items: center;
  /*align-items属性定义项目在交叉轴上如何对齐。flex-start就是从y轴的最上端开始排列*/
  -webkit-box-align: start;
      -ms-flex-align: start;
          align-items: flex-start;
  /*flex-wrap属性定义，如果一条轴线排不下，如何换行。wrap：换行，第一行在上方。*/
  -ms-flex-wrap: wrap;
      flex-wrap: wrap;
  }
  .container .emoji-container .icon {
  margin-right: 40px;
  margin-bottom: 40px;
  }
  .container .emoji-container .icon:nth-child(6n) {
  margin-right: 0px;
  }
  .icon {width: 125px;height: 120px;position: relative;}
  .icon .frog {position: absolute; top: 0;left: 0;width: 100%;height: 100%;}

General style of frogs

• Observe the expressions of each frog. Although each expression has a different shape, their bodies , mouth, eyes, and the position and size of the small blush are almost the same. We can write these consistent styles as common styles, and then write a single style for each frog's characteristics according to each person's frog ID for redrawing or overwriting.

  <div class="frog" id="frog-1">
        <!-- 蛙蛙的身体部分 -->

The first little frog

A little frog

• The first little frog has a dynamic effect with the corners of its mouth rising based on the basic style, so to complete the drawing of the first frog, just create it in the public Just add the animation of the mouth based on the style, and the dom structure is the same.

  .frog#frog-1 .body .mouth {width: 18px;height: 22px;border-bottom: 3px solid #3F6A34;position: absolute;top: 6px;left: 0;right: 0;-webkit-animation: smile 3.8s linear 0s infinite;animation: smile 3.8s linear 0s infinite;
  }
  @-webkit-keyframes smile {
  0% {  border-radius: 0%;
  }
  20% {  border-radius: 50%;
  }
  70% {  border-radius: 50%;
  }
  }
  @keyframes smile {
  0% {  border-radius: 0%;
  }
  20% {  border-radius: 50%;
  }
  70% {  border-radius: 50%;
  }
  }

The second little frog

• The mouth of the second little frog is a big mouth, and there are two small blushes on the cheeks. The eyes are filled with love, so a blush div must be added to the dom structure. The style of the mouth and eyes should also be modified accordingly. (Mainly the production of mouth, blush and red heart)

##The second frog animation.gif

The third little frog

• The changes of the third little frog relative to the public style are the changes of the eyes and mouth, so the most important thing is to draw Left eye style and mouth style.

• The tongue is made into an ellipse, rotated at the corresponding angle and pressed, and then a part of it is covered by the mouth.
