Problems adding custom CSS to Vuetify component

Question

I'm working with the Vuetify selector input component, v-select, and I want to custom style it. Since the component renders with only one v-select and no necessary children in the html, I turned to styling the component via inspecting in chrome and copying down the class there. For example, to change the font size of the active value, I used:

.v-select__selections {
    font-size: 20px;
}

This worked fine, until I realized my styles in this manner did not work on any parts of the (normally hidden) navigation drawer. For example,

.v-menu__content {
    height: 500px;
}

Would not impact the styles in any way. Bizarrely enough, it was not simply my styles getting overwritten by Vuetify styles (!important had no effect) - it appeared that my CSS didn't reach the components at all. There was no trace of any of my written styles upon inspect. How?

I believe this is due to the active-based nature of the drawer-part of the selector component. Is there another way I should be addressing those kinds of elements in CSS? I wish I could provide a Jsfiddle, but (on the templates I've found), Vuetify renders completely differently. I'm using Vuetify 1.1.7.

My styles are included directly in the component .vue file, non scoped. Vuetify and vuetify styles are imported in main.js:

import Vuetify from 'vuetify'
import 'vuetify/dist/vuetify.min.css'
import 'material-design-icons-iconfont/dist/material-design-icons.css'

File structure (Default structure from vue init webpack -myProject):

src/
    -main.js 
    -app.vue 
    -components/
        -problematicComponent.vue
index.html

Edit: I also tried using deep selectors, but the problem still remained with the hidden menu components:

>>>.v-menu__content {
    height: 500px;
}

Therefore the problem I have is different than the problem here:

Vuetify - CSS not working (taking effect) inside component

Answer 1

I once had a similar problem with the vuetify selector component using SCSS. Are you addressing .v-menu__content as nested inside .v-select? Because, interestingly enough, it isn't a child. It is at the same level as v-app (For whatever reason).

Make sure

.v-menu__content {
    height: 500px;
}

isn't nested inside any other components in your SCSS.
