placement of the input component and formatting

I am having some issues (ANCC 2019 and 2020 alike) with input components I format dynamically.

They appear shifted and have different height tho the height is assigned in CSS on different computers.

Below is the code and some screenshot to show the difference.

incorrect position

//  ***************** initial formatting  ***********************
setTimeout(function () {
	$(".ui-textinput").attr("autocomplete","off");
	$(".ui-textinput").css({
		"color": "black",
		"background": "#C1F7F2",
		"font-family": "'Nunito', sans-serif",
		"border": "none",
		"font-size": 24,
		"font-weight": 600,
		"text-align": "center",
		"height": 33
	});

}, 0);

function changetoLowerCase(evt) {
	// allow only letters
	var regex = /[^a-zA-Z]/g;
	evt.target.value = evt.target.value.replace(regex, "");
	// limit the number of characters to the longest word + 1
	evt.target.maxLength = 12;

}
// ******************* events: keyup, focus, blur ****************************
// Note: blur removes the focus on an element

S2formatting.forEach(formatBox);

function formatBox(box) {
	$("#dom_overlay_container").on("keyup", box, changetoLowerCase.bind(this));
	$("#dom_overlay_container").on("focus", box, addBorder.bind(this));
	$("#dom_overlay_container").on("blur", box, removeBorder.bind(this));

	function addBorder() {
		$(box).css({
			"border": "3px solid black"
		});
	}
	function removeBorder() {
		$(box).css({
			"border": "none"
		});
	}

}
