我们来谈谈项目中遇到的需要兼容pc端和移动端的css布局
首先在head里面需要引入移动端属性:<meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
1.css布局方式之div + css布局;
<!-- html --> <div class="box"> <div class="pic_box"> <img src="./images/pic.png" alt=""> </div> <div class="content_box"> <div class="title"> <img src="./images/title.png" alt=""> <span class="tip">标题: div + css布局</span> <!-- <p class="tip">标题: div + css布局</p> --> </div> <div class="content"> <p>内容: 兼容pc端和移动端的css布局</p> </div> </div> </div> <!-- js --> <script> (function () { var html = document.documentElement; // 获取屏幕宽度 var hwidth = html.getBoundingClientRect().width; // 设置html标签的font-size 大小为hwidth/15 html.style.fontSize = hwidth/10 + 'px'; })() </script>
/ css /
html,
body {
margin: 0;
}
.box {
margin: 0.4rem;
}
.box .pic_box img {
width: 3rem;
}
.box .content_box {
float: right;
margin-top: -2.7rem;
width: 6rem;
font-size: initial;
}
.box .content_box .title {
height: 0.7rem;
margin-bottom: 0.2rem;
}
.box .content_box .title img {
width: 0.7rem;
height: 0.7rem;
vertical-align: -25%;
}
.box .content_box .title .tip {
/ float: right; /
line-height: 0.7rem;
}
.content {
font-size: 0.4rem;
}
p {
margin: 0;
}

2.css布局方式之弹性布局(flex布局);
<!-- html --> <div class="box"> <div class="pic_box"> <img src="./images/pic.png" alt=""> </div> <div class="content_box"> <div class="title"> <img src="./images/title.png" alt=""> <p>标题: flex布局</p> </div> <div class="content"> <p>内容: 兼容pc端和移动端的css布局</p> </div> </div> </div>
/ css /
html,
body {
margin: 0;
}
.box {
display: flex;
justify-content: space-between; / 水平两边对齐 /
align-items: center; / 垂直居中 /
margin: 0.6rem;
}
.box .pic_box img {
width: 8rem;
}
.box .content_box {
margin-left: 2rem;
}
.box .content_box .title {
display: flex;
align-items: center;
padding-bottom: 0.6rem;
}
.box .content_box .title img {
width: 32px;
height: 32px;
}
.box .content_box .title p {
margin-left: 0.5rem;
}
.content p {
font-size: 0.8rem;
}
p {
margin: 0;
}

flex布局需要注意的是: 设置弹性布局flex后, 浮动float, clearfix 和vertical-align 等属性均无效!
3.css布局方式之网格布局(grid布局);
/ css /
html,
body {
margin: 0;
}
.box {
display: grid;
align-items: center; / 垂直居中 /
justify-items: right; / 右对齐 /
grid-template-columns: 8rem auto; / auto表示由浏览器自己决定长度 /
grid-gap: 20px;
margin: 0.6rem;
}
.box .pic_box img {
width: 8rem;
}
.box .content_box {
justify-items: left; / 左对齐 /
display: grid;
}
.box .content_box .title {
display: grid;
grid-template-columns: 45px auto;
}
.box .content_box .title img {
width: 32px;
height: 32px;
}
.box .content_box .title p {
line-height: 32px;
}
.content p {
font-size: 0.8rem;
}
p {
margin: 0;
}
<!-- html --> <div class="box"> <div class="pic_box"> <img src="./images/pic.png" alt=""> </div> <div class="content_box"> <div class="title"> <img src="./images/title.png" alt=""> <p>标题: grid布局</p> </div> <div class="content"> <p>内容: 兼容pc端和移动端的css布局</p> </div> </div> </div> 移动端效果图:

使用grid布局的时候需要注意:设置网格布局以后, 容器子元素的float, display: inline-block,display: table-cell, vertical-align和column- 属性均无效!
总结:如果需要兼容ie8的时候建议采用div+ css 布局方式, 不过未来移动端 flex布局和grid布局是个大趋势!
