Overlay on hover in vue.js - vue.js

Question

Im trying to implement displaying text when hovering over an image in vue.js but I am a bit stuck. Im trying to implement this example on an array with multiple images:
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_image_overlay_fade
I got a pretty big vue file but here is the essential:
template:
</template>
[...]
<div v-for="item in filteredPeople" v-bind:key="item.id" class="list-complete-item">
<router-link #mouseover.native="hovertext" :to="'/'+item.link">
<img class="list-complete-img" :src="'http://placehold.it/400x300?text='+item.id" alt>
</router-link>
</div>
[...]
</template>
script
<script>
export default {
data() {
return {
info: [
{
id: 1,
title: "Title one",
link: "project1",
hovertext: "project1 hover text lorem lorem lorem",
category_data: {
"1": "Category 1"
}
},
[...]
methods: {
hovertext() {
console.log("");
},
I had some idea to try to use a method to put the text in a div under the image but then I cannot get the text to get above the image on hover. And I cannot get the method right ... Not really sure this is a good way doing it,
I also found this codepen example:

This is pretty close to what I want to do but I cannot get the text to display here either.
I am a bit lost. Any help how to do this in vue?
---------- UPDATE ----------
I want the image boxes to stretch so they always fits the window but I seems to get a gap between my flexbox rows which I cannot seem to get rid of. You can see the white space. I attach my stylesheet.
.list-complete {
display: flex;
height: auto;
flex-direction: row;
flex-flow: row wrap;
}
.list-complete-item {
flex: 0 1 50%;
display: inline-block;
}
.list-complete-item a {
display: inline-block;
position: relative;
width: 100%;
height: auto;
outline: 1px solid #fff;
}
.list-complete-img {
width: 100%;
}
.text {
color: rgb(186, 74, 74);
position: absolute;
top: 50%;
left: 50%;
-webkit-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
text-align: center;
}
.list-complete-item a:hover .overlay {
opacity: 1;
}
.overlay {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
overflow: hidden;
height: 60%;
width: 100%;
opacity: 0;
transition: 0.5s ease;
background-color: #008cba;
}

You don't need to use js(vue) events. Do it with plain css, like in example you linked to.
Go with this template:
<div v-for="item in filteredPeople" v-bind:key="item.id" class="list-complete-item">
<router-link :to="'/'+item.link">
<img class="list-complete-img" :src="'http://placehold.it/400x300?text='+item.id" alt>
<div class="overlay">
<div class="text">{{ item.hovertext }}</div>
</div>
</router-link>
</div>
And style it up:
.list-complete-item {
width: 400px;
height: 300px;
display: inline-block;
}
.list-complete-item a {
display: inline-block;
position: relative;
width: 400px;
height: 300px;
}
.list-complete-item a .image {
display: block;
width: 100%;
height: auto;
}
.list-complete-item a .overlay {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
height: 100%;
width: 100%;
opacity: 0;
transition: .5s ease;
background-color: #008CBA;
}
.list-complete-item a:hover .overlay {
opacity: 1;
}
.list-complete-item a .text {
color: white;
font-size: 20px;
position: absolute;
top: 50%;
left: 50%;
-webkit-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
text-align: center;
}
And the final result:
