How to increase a PayPal custom amount box width

I have my base font size high, but that means the text in the Paypal total box doesn't fit in the box, any thing over three numbers is being cut off. How do you increase the size of the box to fix this?

We can increase the custom amount input width by adding the following CSS code to the form.

input[id*="_donation"] {
width: 100px;
}

Where 100px; is a new size in pixels.
