页面的head部分相对来说比较简单，基本很容易能看懂的，代码如下：

body {
    width: 430px;
    margin: 0 auto;
    background-color: #F7CAC9;
    font-family: 'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;
}

.search__container {
    padding-top: 48px;
}

.search__title {
    font-size: 22px;
    font-weight: 900;
    text-align: center;
    color: #ff8b88;
}

.search__input {
    width: 100%;
    padding: 12px 24px;
    background-color: transparent;
    transition: transform 250ms ease-in-out;
    font-size: 14px;
    line-height: 18px;
    color: #575756;
    background-color: transparent;
    background-image: url(images/ic_search_black_24px.svg);
    background-repeat: no-repeat;
    background-size: 18px 18px;
    background-position: 95% center;
    border-radius: 50px;
    border: 1px solid #575756;
    transition: all 250ms ease-in-out;
    backface-visibility: hidden;
    transform-style: preserve-3d;
}

.search__input::placeholder {
    color: rgba(87, 87, 86, 0.8);
    text-transform: uppercase;
    letter-spacing: 1.5px;
}

.search__input:hover,
        .search__input:focus {
    padding: 12px 0;
    outline: 0;
    border: 1px solid transparent;
    border-bottom: 1px solid #575756;
    border-radius: 0;
    background-position: 100% center;
}

.credits__container {
    margin-top: 24px;
}

.credits__text {
    text-align: center;
    font-size: 13px;
    line-height: 18px;
}

.credits__link {
    color: #ff8b88;
    text-decoration: none;
    transition: color 250ms ease-in;
}

.credits__link:hover,
        .credits__link:focus {
    color: rgb(191, 137, 135);
}

页面的body部分很简单，一个div容器里放了一个p标签和type为文本的input输入框，代码如下：

<div class="search__container">
    <p class="search__title">试着鼠标悬停在搜索框上吧</p>
    <input class="search__input" type="text" placeholder="搜一下就出来了">
</div>
