1、电池

成果：

难点： 电池电量 100% 时凸出来的那局部红色怎么变成红色？（即电池正极凸出来的那局部怎么填充色彩？）
解决： 电量 100% 时让显示电量的红色 div 溢出整个电池，并在电池凸出来局部的两边别离应用一个红色 div 盖住即可。如图：

未盖住：

盖住了：

代码实现：

<style>
.dyestuff-battery{
        display: inline-block;
        position: relative;
        width: 98px;

2、水彩笔

成果：

难点： 等腰梯形的绘制
解决： 应用 clip-path 绘制等腰梯形
代码实现：

<style>
.dyestuff-watercolor-pen{
        display: inline-block;
        width: 40px;
    }
    .dyestuff-watercolor-pen + .dyestuff-watercolor-pen{margin-left: 20px;}
    .dyestuff-watercolor-pen .penpoint{
        width: 8px;
        height: 8px;

<div>
    <div class="dyestuff-watercolor-pen">
        <div class="penpoint"></div>
        <div class="pen-head">
            <div class="pen-head-inner"></div>
        </div>
        <div class="pen-body"></div>
        <div class="pen-cap"></div>

        <div class="pen-body" style="background-color: #FFF000;"></div>
        <div class="pen-cap" style="background-color: #FFF000;"></div>
    </div>
</div>

3、铅笔

成果：

难点： 等腰三角形的绘制
解决： 应用 clip-path 绘制等腰三角形
代码实现：

<style>
.dyestuff-pencil{
        display: inline-block;
        width: 24px;
    }
    .dyestuff-pencil + .dyestuff-pencil{margin-left: 20px;}
    .dyestuff-pencil .penpoint{
        position: relative;
        height: 46px;
        border: 1px solid #000;
        background-color: #000;
        clip-path: polygon(50% 0, 100% 100%, 0 100%);
    }
    .dyestuff-pencil .penpoint::before{
        position: absolute;
        content: ' ';
        left: 0;
        right: 0;
        top: 10px;
        height: 1px;
        z-index: 2;
        background-color: #000;
    }
    .dyestuff-pencil .penpoint-inner{
        position: absolute;
        left: 0;
        right: 0;
        bottom: 0;
        top: 0;
        background-color: #D92622;
        clip-path: polygon(50% 0, 100% 100%, 0 100%);
    }
    .dyestuff-pencil .pen-body{
        height: 230px;
        border: 1px solid #000;
        border-top: none;
        background-color: #D92622;
    }
</style>

<div>
    <div class="dyestuff-pencil">
        <div class="penpoint">
            <div class="penpoint-inner"></div>
        </div>
        <div class="pen-body"></div>
    </div>
    <div class="dyestuff-pencil">
        <div class="penpoint">
            <div class="penpoint-inner" style="background-color: #FBCC96;"></div>
        </div>
        <div class="pen-body" style="background-color: #FBCC96;"></div>
    </div>
</div>

4、蜡笔

成果：

难点： 圆角等腰三角形的绘制
解决： 应用 rotate+skewX 绘制
瑕疵 直角与三角相接的中央不能重合，如图(有更好方法的大佬麻烦提供下代码)：

代码实现：

<style>
.dyestuff-crayon{
        display: inline-block;
        width: 24px;
    }
    .dyestuff-crayon + .dyestuff-crayon{margin-left: 20px;}
    .dyestuff-crayon .penpoint{
        height: 24px;
        border: 1px solid #000;
        border-right: none;
        border-bottom: none;
        transform: rotate(57deg) skewX(20deg);
        border-top-left-radius: 6px;
        margin-bottom: -12px;
        background-color: #D92622;
    }
    .dyestuff-crayon .pen-body{
        height: 230px;
        border: 1px solid #000;
        border-top: none;
        margin: 0 -2px;
        background-color: #D92622;
    }
</style>

<div>
    <div class="dyestuff-crayon">
        <div class="penpoint"></div>
        <div class="pen-body"></div>
    </div>
    <div class="dyestuff-crayon">
        <div class="penpoint" style="background-color: #00A3DA;"></div>
        <div class="pen-body" style="background-color: #00A3DA;"></div>
    </div>
</div>
