fill input from right to left

The way is to look for a plugin that fits your needs. Unless, of course, you have a very specific requirement and choose to develop your own library.

So start here:

link or link

Try this one: link

Or this one: link

Solution using text-align :

input {
  text-align: right;
}

<input type="text">

The solutions below using the dir attribute should apply only to languages which are written from right to left (like Arabic):

Using HTML using the dir='rtl' (right to left) attribute:

<input name="DinheiroQueEhBomEuNaoTenho" dir="rtl" />

With CSS through the direction property.

  

The direction property defines the direction in which the text is written.

Definition - direction

See an example:

input{
  direction: RTL;
}

<input name="DinheiroQueEhBomEuNaoTenho" />
