setting vue modal mask to blur - html

Question

I'm trying to add a blur panel behind my modal using vue.js but The problem is that the modal-mask has the content nested in it so to add a filter: blur() property it'll blur everything.
Right now I can only add a black tint to the background.

<div id="img-desc-container">

<div class="description-area"></div>
</div>
</li>
</ul>
<button class="modal-close" #click="$emit('close')">Close</button>
</div>
</div>
</div>
CSS
/* BLUR PANEL */
#modal-mask {
position: fixed;
z-index: 9998;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: rgba(0, 0, 0, .6);
display: table;

}

Answer 1

you'll need to move the content into a separate container and toggle a blur class
https://jsfiddle.net/2eed5qjo/27/
<div :class="{'blur-content': showModal}">
... your content ...
</div>
<!-- use the modal component, pass in the prop -->
<modal v-if="showModal" #close="showModal = false">
</modal>
then add a css class like this
.blur-content{
filter: blur(5px);
}
