What steps can I take to troubleshoot when my vue.js styles are not being applied correctly?

I am trying to make these 2 styles work together

<style scoped>
>>> .description {
    white-space: nowrap !important;
    color: red;
}

>>> li a {
    text-decoration: none !important;
}
</style>

Please review my code below

                    <v-card-text class="text-center"

<template> elements are not rendered in vue@2, so when you add a class to a <template> it appears as an empty attribute in the HTML output. The presence of the empty class attribute is likely due to the <router-link> element. It's possible that the .description class relates to text content marked as "urgent" within the element. You have options for handling this issue:

<template v-slot:item.description="{ item }" class="description" style="overflow-wrap: normal">
  {{ item.description }}
</template>

You could replace the above code with something like the following (using a different HTML element such as span or p):

<div v-slot:item.description="{ item }" class="description" style="overflow-wrap: normal">
  {{ item.description }}
</div>

If you wish to apply the .description class to the <a> tag, consider adding the class to a router-link instead.
