Make payment Total Amount due input box wider

Now the next thing is how to integrate that to Paypal. if you will check my cloned form I have integrated and chosen User-defined value, is that correct?

If yes, I have then selected to take the value from Total, But it shows like this.https://gyazo.com/81dd6ca9d4278c7e54b470d28a50bfbc

The total amount does not have enough space to show up, It's hiding the .99 cents figure and I am unable to increase it's width

You can inject the following CSS codes into your form.

It will make the Paypal Total input box wider. You can change the 70px value as needed.

input[id*="_donation"] {

    width: 70px;

}
