content: Missing Import of Css file

### URL

https://ionicframework.com/docs/api/datetime

### Issue Description

I was having issues with using datetime for the first time in my vue app, I am new to ionic framework so I followed the docs to implement the functionality, but i got stuck styling a selected date, only for me to discover that i needed to import the style library, and this was not stated in the documentation I had to import the style in my main.ts:

import '@ionic/vue/css/ionic.bundle.css';
