大家好，我是小张

本期案例，用前端三件套实现一个简约的响应式布局网页，当屏幕分辨率自适应改变时网页布局会自动发生切换，网页布局同时兼容PC端和移动端，

在普通PC屏幕下网页布局效果

移动端网页布局：

除了基础布局外，借助 scrollreveal 插件，在网页中加入了一些动画，

例如网页首次打开时，

左侧图标由左向右延迟 500ms 出现，透明度从 100 到 0;
中间标题和图片由下向上延迟 400ms 出现，透明度从 100 到 0;

代码实现

本案例案例中 html 代码部分

案例中用到了连个 icon 库，以及谷歌字体，都采用在head 标签中通过 CDN 方式加入到项目中；
此外，由于案例中用到 scrollreveal 插件来实现动画，该插件也是通过 CDN 方式载入；

案例 JS 部分，主要控制移动端菜单栏的出现与消失；以及一些浮动动画

// 中部
const scrollRevealOpt1 = {
    delay: 400,
    distance: '100px',
    duration: 600,
    easing: 'cubic-bezier(0.5, 0, 0, 1)',
    interval: 0,
    opacity: 0,
    origin: 'bottom'
}


const scrollRevealOpt2 = {
    delay: 400,
    distance: '100px',
    duration: 500,
    easing: 'cubic-bezier(0.5, 0, 0, 1)',
    interval: 0,
    opacity: 0,
    origin: 'bottom'
}

// 左侧图标区域 动画效果配置
const leftIconsOpt = {
    delay: 400,
    distance: '45px',
    duration: 600,
    easing: 'cubic-bezier(0.5, 0, 0, 1)',
    origin: 'left'
}

const leftcontent = document.querySelector('.content .left')
const rightcontent = document.querySelector('.content .right')
const mobileBar = document.getElementById('mobile-bar')
const leftIcons = document.querySelector('.left-icons')


ScrollReveal(scrollRevealOpt1).reveal(leftcontent);
ScrollReveal(scrollRevealOpt2).reveal(rightcontent);
ScrollReveal(leftIconsOpt).reveal(leftIcons)
const menuList = document.querySelector('.menu-bar')
mobileBar.onclick = () => {
    menuList.classList.toggle('open')
    mobileBar.classList.toggle('bx-x')
}
