How to style Vue Formulate input errors? - styles

Question

I write a website with Vue.js and to handle user interface, I want to use Vue Formulate. All in all it works, but I have trouble to style input errors. So, I tried to make a very simple example to change the background color from the error list, but it doesn't work.
That is my easy component:
<template>
<div>
<p>Test for VueFormulate</p>
<FormulateInput
type="text"
validation="required"
/>
</div>
</template>
<script>
export default {
name: 'HelloWorld'
}
</script>
<style scoped>
li.formulate-input-error {
background-color:green;
}
</style>
After the site is loaded and the error list element is there, I can change the background-color in the Google Chrome devtools. But not bevor.
I hope somebody can explain what I have to do to make it work.

Your style block is scoped meaning you cannot style elements that are not in your immediate <template> (that's the point of scoping). You have three options:
Remove the scoped portion of your <style> block. I don't really recommend this.
Move your general form styles to a global css file. I would recommend this if you use more than 1 input.
Use a deep selector like ::v-deep. This is great for case-by-case overrides, and allows you to select elements that are deeper than your current "scope". Here's an example:
<style scoped>
.formulate-input::v-deep li.formulate-input-error {
background-color: green;
}
</style>
