毛玻璃态计算器

效果展示

页面结构组成

从上述的效果可以看出，计算机的页面比较规整，适合grid布局。

CSS3 知识点

• grid 布局

实现计算机布局

<div class="container">
  <form class="calculator" name="calc">
    <input type="text" readonly class="value" name="txt" />
    <span class="num clear" onclick="calc.txt.value = ''">Cspan>
    <span class="num" onclick="document.calc.txt.value += '/'">/span>
    <span class="num" onclick="document.calc.txt.value += '*'">*span>
    <span class="num" onclick="document.calc.txt.value += '7'">7span>
    <span class="num" onclick="document.calc.txt.value += '8'">8span>
    <span class="num" onclick="document.calc.txt.value += '9'">9span>
    <span class="num" onclick="document.calc.txt.value += '-'">-span>
    <span class="num" onclick="document.calc.txt.value += '4'">4span>
    <span class="num" onclick="document.calc.txt.value += '5'">5span>
    <span class="num" onclick="document.calc.txt.value += '6'">6span>
    <span class="num plus" onclick="document.calc.txt.value += '+'">+span>
    <span class="num" onclick="document.calc.txt.value += '1'">1span>
    <span class="num" onclick="document.calc.txt.value += '2'">2span>
    <span class="num" onclick="document.calc.txt.value += '3'">3span>
    <span class="num" onclick="document.calc.txt.value += '0'">0span>
    <span class="num" onclick="document.calc.txt.value += '00'">00span>
    <span class="num" onclick="document.calc.txt.value += '.'">.span>

}

.container .calculator span {

  place-items: center;

  border-right: 1px solid rgba(255, 255, 255, 0.05);
  transition: 0.5s;
}

/* 使用 grid-column 和 grid-row 进行单元格合并 */
.container .calculator .clear {
  grid-column: span 2;
  width: 150px;
  background: rgba(255, 255, 255, 0.05);
}

.container .calculator .plus {
  grid-row: span 2;
  height: 150px;
}

.container .calculator .equal {
  background: rgba(255, 255, 255, 0.05);
}

使用VanillaTilt工具函数让计算器随鼠标旋转

计算器会这鼠标的位置进行旋转，我们采用VanillaTilt工具来帮我们实现。

VanillaTilt.init(document.querySelector(".container"), {
  max: 25,
  speed: 400,
});
