1.1 思路
看了这个gif后可以清楚的看到产生了三个动画效果图片"拉近""了解更多"从下往上显示出来阴影。
我看了华为官网的源代码发现图片本身就是有一个mask的这样能让图片看起来暗一些也就意味着当鼠标进入的时候只需要让mask的背景颜色更深一些就实现了阴影的效果。至于图片"拉近"我早就写过了无非是把图片放大然后超出盒子的不显示这个也容易。但了解更多显现难度就大了一些。我想了很久最后只有通过位置来把"了解更多"显示出来想过用visibility: visible;但效果不太好也想过用Vue的过渡效果但是好像又不能同时产生三个效果。所以笨人先用笨法先能实现再说。

这里需要提一下由于需要操作的是多个div我用了根据类名操作Dom的方式所以需要传一下是第几个Dom
methods: {
showDiv1(value) {
var d1 = document.getElementsByClassName('a_div2')[value - 1];
// alert("悬浮上来了")
d1.style.cssText = 'animation-name:example; animation-duration:0.5s;animation-fill-mode: forwards;z-index:3;'
var d3 = document.getElementsByClassName('a1_img1')[value - 1];
d3.style.cssText = 'animation-name:showBigImg2; animation-duration:0.5s;animation-fill-mode: forwards; '
var d2 = document.getElementsByClassName('mask')[value - 1];
d2.style.cssText = ' z-index:2; background: linear-gradient(rgba(0, 0, 0, 0) 0%, rgba(0, 0, 0, 0.4) 70%);'
},
hideDiv1(value) {
var d1 = document.getElementsByClassName('a_div2')[value - 1];
d1.style.cssText = ' animation-name:backwards; animation-duration:0.5s;animation-fill-mode: forwards;z-index:3;';
var d3 = document.getElementsByClassName('a1_img1')[value - 1];
d3.style.cssText = 'animation-name:cancelBigImg2; animation-duration:0.5s;animation-fill-mode: forwards; '
var d2 = document.getElementsByClassName('mask')[value - 1];
d2.style.cssText = 'background: linear-gradient(rgba(0, 0, 0, 0) 0%, rgba(0, 0, 0, 0.3) 70%);z-index:2;'
// d1.style.cssText = ' animation-name:backwards; animation-duration:0.5s;animation-fill-mode: forwards;';
}
}
要记得设置一下mask的z-index级别比图片大即可不然在图片放大的过程中mask会被遮挡住这样就实现不了阴影的效果而且很突兀。

1.3 知识补充
在写这个效果的时候我遇到了一个很大的问题就是鼠标一旦离开这个框如下的位置动画效果就会被取消。我尝试了各种方法都无济于事。起初我以为是子组件遮挡住了父组件导致所以一度往如何让子组件彻底变成父组件的一部分上思考。但后来搜索Vue中的鼠标事件的时候得到了解决。
原因是因为最开始我用了mouseout鼠标事件而mouseout事件一旦离开父元素或者子元素都会触发所以鼠标离开子元素的时候也会触发父元素上的mouseout鼠标事件但是mouseleave则不同只有离开被选元素的时候才会触发效果这样遇到的问题就被完美解决了。

2.1 思路
这个实现起来很容易"了解更多"按钮和父组件分别使用position:absolute , position:relative然后"了解更多"按钮相对于父组件定位利用top和left(或者bottom、right)定位将其放置在合适的位置。
至于"了解更多"的悬浮效果则通过:hover即可实现

3 新闻与活动
3.1 思路
首先是分成三个组件,宽度为30%,中间两个间距分别为5%。
第一第二两个组件的形式一样都是分成三大部分展会活动、图片、内容信息。
其中展会活动很显然用到了相对父组件定位图片和内容使用普通定位即可
另外当鼠标悬浮上去的时候图片会被拉近而内容信息的颜色会变深一些。
当然这个也不是很难大多数都是用过的知识。
对于第三个组件相对复杂一些。所谓相对复杂也不过是因为一个hover实现不了这个效果。因为如果用悬浮的话要求两个字体的color都需要继承父组件但是这样的话就不能保证两个字体的颜色不同所以需要用到一个鼠标事件对两者的Dom进行操作实现。
