HTML+CSS+JS实现 ❤️基于Javascript简单计算器特效❤️_计算器_02

主要代码实现：

CSS样式：

    display: flex;
    justify-content: center;
    align-items: center;
    min-height: 100vh;

}

.overall {
    background-color: #e3e7f1;
    --button-width: 80px;
    --button-height: 80px;
    box-shadow: -8px -8px 16px -10px rgba(255, 255, 255, 1), 8px 8px 16px -10px rgba(0, 0, 0, .9);
    padding: 44px 24px 24px 24px;
    border-radius: 20px;
    display: grid;
    grid-template-areas: "result result result result" "AC plus-minus percent divide" "num-7 num-8 num-9 multiply" "num-4 num-5 num-6 subtract" "num-1 num-2 num-3 add" "num-0 num-0 dot equal";
    grid-template-columns: repeat(4, var(--button-width));
    grid-template-rows: repeat(6, var(--button-height));
}

/* æŒ‰é’® */

.overall button {
    display: block;
    outline: none;
    border-radius: calc(var(--button-height)/3);
    font-size: 24px;
    font-family: Helvetica;
