How I Override CSS in PrimeVue (and kept my sanity)

Written by

I’m Kayla, and I’ve been building a dashboard with PrimeVue on Vue 3. I love the speed. But styling? It felt like whack-a-mole at first. Buttons looked one way in one spot, and another way in a dialog. You know what? I had to learn a few tricks. Now it’s smooth.
If you’d like the full story with a few extra war-stories, I broke it down in how I override CSS in PrimeVue (and kept my sanity).

Let me explain what worked for me, with real code I used.

The first secret: load order

My first miss was simple. My CSS loaded before the theme. So the theme won every fight.
A similar tangle hit me in WordPress when I yanked out the editor styles—see my notes in I removed Gutenberg CSS in WordPress—was it worth it?.

Here’s what fixed it. I import the theme and PrimeVue core first. Then my overrides come last.
A handy visual guide to CSS precedence lives on CSS Menu Tools, and it saved me from a few late-night order mistakes.

// main.js (PrimeVue v3 style)
import { createApp } from 'vue'
import PrimeVue from 'primevue/config'

// 1) Theme and core
import 'primevue/resources/themes/lara-light-blue/theme.css'
import 'primevue/resources/primevue.min.css'
import 'primeicons/primeicons.css'

// 2) My overrides LAST
import '@/assets/prime-overrides.css'

import App from './App.vue'

createApp(App).use(PrimeVue).mount('#app')

If you’re on a newer setup, your theme path may look a bit different. The idea stays the same: theme first, your CSS last.

Plain, global overrides that actually stick

Once the order was right, this worked fine for me:

/* assets/prime-overrides.css */

/* Buttons: round and bold */
.p-button {
  border-radius: 12px;
  font-weight: 600;
}

/* Inputs: taller fields */
.p-inputtext {
  height: 44px;
  padding: 0 12px;
}

/* DataTable: soft header */
.p-datatable .p-datatable-thead > tr > th {
  background: #f8fafc;
  color: #1f2937;
  position: sticky;
  top: 0;
  z-index: 1;
}

Short, clean, and it works. I felt silly that I fought this for a whole morning.
(If you’re wrangling CSS inside a hosted site builder, my walkthrough on how I add CSS in the Website.com builder and what actually stuck shows the same principles in a no-code environment.)

Scoped styles blocking you? Use :deep

In Vue Single File Components, I use scoped styles a lot. That’s nice, but it hides your CSS from PrimeVue’s internal classes. So I use :deep(...) when I need to reach them.

<template>
  <Button label="Save" class="mx-2" />
</template>

<style scoped>
:deep(.p-button) {
  padding: 0.65rem 1rem;
  border-radius: 14px;
}
</style>

No :deep, no override. I learned that the hard way.

When I want clean hooks: PassThrough classes

Sometimes I don’t want to fight selectors. I just add my own class through the PassThrough prop. So tidy.

<template>
  <Button
    label="Delete"
    :pt="{ root: { class: 'btn-danger' }, label: { class: 'btn-uppercase' } }"
  />
</template>

<style>
.btn-danger {
  background: #ef4444;
  border-color: #ef4444;
  color: #fff;
}
.btn-danger:hover {
  background: #dc2626;
  border-color: #dc2626;
}
.btn-uppercase {
  text-transform: uppercase;
  letter-spacing: 0.02em;
}
</style>

Less wrestling. More control.

Theme variables for big, fast changes

PrimeVue themes (like Lara) use CSS variables. Tweaking them gave me a full reset without touching every component. You can dive deeper in the official Styled theming guide to see every variable and palette option spelled out.

I placed this in my global CSS:

:root {
  --primary-500: #16a34a;  /* main brand color */
  --primary-600: #15803d;
  --text-color: #111827;
  --surface-ground: #f1f5f9;
}

Note: variable names depend on the theme you picked. I tested with Lara. If a color doesn’t change, I peek at the theme CSS and copy the right var name. Not fancy—just honest snooping.

Real overrides I ship often

Here are a few I use in real screens.

/* Buttons: size scale */
.p-button.p-button-sm { padding: 0.4rem 0.7rem; }
.p-button.p-button-lg { padding: 0.9rem 1.25rem; }

/* Outlined buttons: better contrast */
.p-button.p-button-outlined {
  border-width: 2px;
}

/* Calendar input: match input height */
.p-calendar .p-inputtext {
  height: 44px;
}

/* Chips: softer corners */
.p-chips .p-chips-token {
  border-radius: 10px;
  background: #e5f6ff;
  color: #0369a1;
}

/* Dialog header: compact look */
.p-dialog .p-dialog-header {
  padding: 0.75rem 1rem;
  border-bottom: 1px solid #e5e7eb;
}

It’s the little things that make the UI feel calm.

In fact, one of my freelance gigs involved polishing the CSS for a boutique dating landing page focused on Kansas-area professionals.

Tailwind plus PrimeVue (yes, this works)

I do mix Tailwind. When I need a one-off, I go loud with utility classes. I use the exclamation to win the fight.

<Button
  label="Pay Now"
  class="!bg-emerald-600 !border-emerald-600 !text-white hover:!bg-emerald-700"
/>

Is it pretty? Not always. Is it fast? Very.

When nothing works… use stronger selectors (or the nuclear flag)

Most times, higher weight fixes it. A parent class helps. If you're curious, a classic Stack Overflow answer on overriding default PrimeFaces CSS with custom styles shows the same specificity tricks that still apply in PrimeVue.

/* Stronger than a plain .p-button */
.checkout-page .p-button {
  border-radius: 9999px;
}

If a component injects inline styles (some do), I use !important sparingly:

.p-button {
  letter-spacing: 0.02em !important;
}

I don’t love it. But hey, the ship date is real.

Little snags I hit (and fixed)

  • My stylesheet came first. The theme beat me. Fix: load my CSS last.
  • Scoped styles did nothing. Fix: use :deep(...).
  • Wrong theme vars. Fix: open the theme CSS and copy the real var names.
  • Nuxt build hid my CSS. Fix: add overrides in the main assets file and register it in the app entry.

I also ran into a dialog that reset button styles. My fix was a page-level wrapper class with a stronger selector. Quick and clean.

My short checklist (taped to my monitor)

  • Theme and core CSS first, my overrides last.
  • For SFC scoped styles, use :deep(...).
  • Use PassThrough to add clean, custom classes.
  • For wide changes, set theme variables.
  • If stuck, raise selector weight. Last resort, !important.

Honestly, once I learned these five moves, styling PrimeVue felt easy. Not magical—just steady and clear. And now my buttons look like my brand, not a demo theme. That’s a small win that feels big.
