Here is the block of code in HTML and CSS

```css
.Container {
  position: relative;
}

.Dollarsign {
  position: absolute;
  font-weight: bold;
  font-size: 24px;
  color: green;
  text-align:center;
}

.Input {
  font-weight: bold;
  font-size: 48px;
  position: relative;
  text-align:center;
}
```

```html
<div class='Container'>
  <div class='Input '>
    <div class='Dollarsign'>$</div>
    20213</div>
</div>
```

I would like the dollar sign to be right next to the numbers and adjusts position if the number increases or decreases.
