代码解读
定义 dom,容器中包含 2 个元素,分别代表屏幕和底座:
<div class="macbook">
<span class="screen"></span>
<span class="base"></span>
</div>
居中显示:
body {
margin: 0;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
background: radial-gradient(circle at center, white, gray);
}
定义容器尺寸:
.macbook {
width: 50em;
font-size: 10px;
display: flex;
flex-direction: column;
align-items: center;
}
画出屏幕的轮廓:
.screen {
width: 40em;
height: calc(40em * 0.667);
background-color: black;
border-radius: 3% 3% 0 0 / 5%;
border: 0.2em solid silver;
border-bottom: none;
position: relative;
}
画出屏幕上的光影:
.screen {
position: relative;
}
.screen::before {
content: '';
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background: radial-gradient(
circle at right bottom,
rgba(255, 255, 255, 0.4) 75%,
rgba(255, 255, 255, 0.6) 75%
);
margin: 4.3% 3.2%;
}
画出底座的轮廓:
.base {
position: relative;
}
.base {
width: inherit;
height: 1.65em;
background: linear-gradient(
white,
white 55%,
#999 60%,
#222 90%,
rgba(0, 0, 0, 0.1) 100%
);
border-radius: 0 0 10% 10% / 0 0 50% 50%;
}
为底座增加光照效果:
.base::before {
content: '';
position: absolute;
width: inherit;
height: 55%;
background: linear-gradient(
to right,
rgba(0, 0, 0, 0.5) 0%,
rgba(255, 255, 255, 0.8) 1%,
rgba(0, 0, 0, 0.4) 4%,
transparent 15%,
rgba(255, 255, 255, 0.8) 50%,
transparent calc(100% - 15%),
rgba(0, 0, 0, 0.4), calc(100% - 4%),
rgba(255, 255, 255, 0.8) calc(100% - 1%),
rgba(0, 0, 0, 0.5) 100%
);
}
画出底座上用于掀开屏幕的缺口:
.base::after {
content: '';
position: absolute;
width: 7em;
height: 0.7em;
background-color: #ddd;
left: calc(50% - 7em / 2);
box-shadow:
inset -0.5em -0.1em 0.3em rgba(0, 0, 0, 0.2),
inset 0.5em 0.1em 0.3em rgba(0, 0, 0, 0.2);
border-radius: 0 0 7% 7% / 0 0 95% 95%;
}
大功告成!
