Override default transition styles

[chrisjansky]

Hi,

Thanks for a wonderful library.

Is there a way to override the default slide + fade transitions when a toaster appears? I am specifically looking to change the easing and do without changing of the opacity (only slide in from the edge of the screen).

Thanks for any pointers.

Hi, if you are using v2, you can copy the vue-sonner styles, apply your changes, then import your own vue-sonner CSS file to your app

The CSS content is in Toaster.vue

If it is hard to copy the CSS from Toaster.vue, you can copy it from the npm build

https://www.npmjs.com/package/vue-sonner?activeTab=code ===> lib/index.css file

index.css

Now, instead of importing the CSS file from vue-sonner/style.css do this

- import 'vue-sonner/style.css'
+ import './my-own-copy-of-vue-sonner-style.css

If you are using vue-sonner Nuxt module, make sure to disable/false the CSS option

export default defineNuxtConfig({
