代码解读
定义 dom,容器包含 5 个元素,分别代表纸张、尺子、记事本、日历和铅笔。
<div class="desk">
<span class="paper"></span>
<span class="ruler"></span>
<span class="notebook"></span>
<span class="calendar"></span>
<span class="pencil"></span>
</div>
居中显示:
body {
margin: 0;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
定义容器尺寸:
.desk {
width: 70em;
height: 70em;
font-size: 5px;
position: relative;
}
定义各元素的共有属性:
.desk {
--b: 1em solid darkslategray;
}
.desk * {
position: absolute;
border: var(--b);
box-sizing: border-box;
}
.desk *::before,
.desk *::after {
content: '';
position: absolute;
box-sizing: border-box;
}
画出纸张的轮廓:
.paper {
width: 24em;
height: 30em;
color: skyblue;
background-color: currentColor;
border-radius: 0 0 0 3em;
top: 14em;
left: 4em;
}
画出纸张左侧卷曲的部分:
.paper::before {
width: 4em;
height: 32em;
background-color: currentColor;
border: var(--b);
filter: saturate(150%) brightness(0.9);
bottom: 1.6em;
left: -1em;
border-radius: 3em 0 3em 0;
}
.paper::after {
width: 4em;
height: 5em;
background-color: currentColor;
border: var(--b);
bottom: -1em;
left: -1em;
border-radius: 2.5em 0 0 2.5em;
border-right: none;
}
画出尺子的轮廓:
.ruler {
width: 6em;
height: 24em;
background: linear-gradient(
to right,
peru 30%,
sandybrown 30%
);
top: 8em;
left: 14em;
transform: rotate(25deg);
}
画出尺子上的长刻度线:
.ruler::before {
width: 2em;
height: calc(100% - 3em);
background-image: linear-gradient(darkslategray 1em, transparent 0);
background-size: 4em 4em;
top: 1em;
}
画出尺子上的短刻度线:
.ruler::after {
width: 1em;
height: calc(100% - 3em);
background-image: linear-gradient(darkslategray 1em, transparent 0);
background-size: 4em 4em;
top: 3em;
}
画出日历的轮廓:
.calendar {
width: 28em;
height: 28em;
background: linear-gradient(coral 30%, white 30%);
border-radius: 2em;
top: 14em;
right: 4em;
transform: rotate(15deg);
}
画出日历顶部的转轴:
.calendar::before {
width: 3em;
height: 4em;
color: sandybrown;
background-color: currentColor;
top: -2em;
left: 4em;
border-radius: 100% 100% 50% 50%;
box-shadow:
0 0, 0 0 0 1em darkslategray,
15em 0, 15em 0 0 1em darkslategray;
}
画出日历上的日期:
.calendar::after {
width: 3em;
height: 3em;
color: silver;
background-color: silver;
top: 10em;
left: 4em;
border-radius: 0.4em;
box-shadow:
0 0, 5em 0, 10em 0, 15em 0,
0 5em, 5em 5em, 10em 5em, 15em 5em,
0 10em, 5em 10em, 10em 10em, 15em 10em;
}
画出记事本的轮廓:
.notebook {
width: 26em;
height: 34em;
background: linear-gradient(
to right,
tomato 12%,
coral 12%, coral 60%,
darkslategray 60%, darkslategray 64%,
sandybrown 64%, sandybrown 78%,
darkslategray 78%, darkslategray 82%,
coral 82%
);
border-radius: 3em;
bottom: 8em;
left: 20em;
}
画出记事本的底部:
.notebook::before {
width: inherit;
height: 5em;
background-color: white;
border: var(--b);
bottom: -1em;
left: -1em;
border-radius: 3em 0 3em 3em;
}
画出记事本的书签:
.notebook::after {
width: 4em;
height: 5em;
background-color: coral;
border: var(--b);
bottom: -3em;
left: 4em;
border-top: none;
border-radius: 0 0 1em 1em;
}
画出铅笔的轮廓:
.pencil {
width: 6em;
height: 12em;
background: linear-gradient(
coral 20%,
darkslategray 20%, darkslategray 25%,
sandybrown 25%
);
border-radius: 0.8em;
bottom: 14em;
right: 13em;
transform: rotate(-35deg);
}
画出铅笔的笔尖:
.pencil::before {
border: 3em solid transparent;
border-top-color: darkslategray;
bottom: -6.5em;
left: -1em;
}
.pencil::after {
border: 2em solid transparent;
border-top-color: sandybrown;
bottom: -4.5em;
left: 0;
}
增加鼠标悬停效果,把物品都推向桌面的边缘:
.desk * {
transition: 1s;
}
.desk:hover .paper {
top: 0;
left: 0;
}
.desk:hover .ruler {
top: 0;
left: 50%;
transform: rotate(0);
}
.desk:hover .calendar {
top: 0;
right: 0;
transform: rotate(0deg);
}
.desk:hover .notebook {
bottom: 0;
left: 0;
}
.desk:hover .pencil {
bottom: 0;
right: 0;
transform: rotate(180deg);
}
dom 中增加文字 “Hey, Take it easy”:
<div class="desk">
<span class="paper"></span>
<span class="ruler"></span>
<span class="calendar"></span>
<span class="notebook"></span>
<span class="pencil"></span>
<p>Hey!<br>Take it easy!</p>
</div>
设置文字样式:
.desk p {
border: none;
color: darkslategray;
font-size: 6em;
font-weight: bold;
font-family: sans-serif;
text-align: center;
bottom: 2em;
right: 1em;
}
最后,为文字增加慢慢浮现的效果:
.desk p {
transform: rotate(-35deg) scale(0);
}
.desk:hover p {
transform: rotate(-35deg) scale(1);
}
大功告成!
