Inline button with field

Hi, I want to add the button to be inline with the field (same row).

I found this code snippet:

#forminator-module-2607 .forminator-row:nth-child(2) {
	margin-right: 0;
}
#forminator-module-2607 button#forminator-submit {
	width: 100%;
	display: block;
}
#forminator-module-2607 #submit {
	display: block;
}
@media only screen and (min-width: 783px) {
	#forminator-module-2607 .forminator-row:nth-child(2) {
		float: left;
		width: calc(100% - 140px);
		margin-right: 2px;
		display: inline-block;
	}
	#forminator-module-2607 #submit {
		display: inline-block;
	}
}

This code works but the button is not exactly aligned with the input field, it slightly above (and right margin) from the row.

Is there a better/updated code for this?

Thanks
