Overlay on hover in 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: https://codepen.io/oliviaisarobot/pen/xzPGvY

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;
}

A lot of what you're trying to do depends on CSS.

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:

I still got one problem, I updated my post above. 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.
