[Vuejs]-How i can do that the div of my template are 100% width and 100% heigth?

To set a element’s height to 100% of the browser window, you can simply use the vh property of CSS:

div {
 height: 100vh;
 width: 100%;
}

It’s good to give this height to the root element of your app, so the root’s height will always be equal to the browser window’s height.

Tip-
If you see a vertical scrollbar after applying vh this is because of extra margin and padding of the body, so do this-

html,
body {
  margin: 0;
  padding: 0;
}
