Is it possible to access or modify the coordinates, width, and height of an element that is statically positioned using only JavaScript? If so, how can this be done in both pure JavaScript and jQuery?

Incorporating jQuery is a viable option for obtaining the vertical and horizontal position of #your_element in relation to its parent using the .position() method.
$('#your_element').position().left
$('#your_element').position().top
You can also determine the dimensions by:
$('#your_element').width()
$('#your_element').height()
Absolutely, you have the capability to do so. Here is a guide to help kickstart your journey.
<html>
<head>
<script>
function determineLocation(e){
//Please note that CSS styles may not be entirely accurate, especially with properties like top/left.
//This display is simply to showcase potential options.
alert(
'Width (CSS): ' + (e.style.width || '') + '\n' +
'Height (CSS): ' + (e.style.height || '') + '\n' +
'Left (CSS): ' + (e.style.left || '') + '\n' +
'Top (CSS): ' + (e.style.top || '') + '\n\n' +
'Width (Offset): ' + e.offsetWidth.toString() + 'px\n' +
'Height (Offset): ' + e.offsetHeight.toString() + 'px\n' +
'Left (Offset): ' + e.offsetLeft.toString() + 'px\n' +
'Top (Offset): ' + e.offsetTop.toString() + 'px'
);
}
function adjustTo5050(){
var targetElement = document.getElementById('adiv');
if (targetElement){
targetElement.style.height = '50px';
targetElement.style.width = '50px';
targetElement.style.left = '50%';
targetElement.style.top = '50%';
};
}
</script>
</head>
<body>
<div id='adiv' style='background: lime' onclick='determineLocation(this)'>Where am I?</div>
<b onclick='adjustTo5050()'>Set to 50px 50px</b>
</body>
</html>
Function expands the capabilities to set and get width and height for a specific element
If you run the code below, you will see that the styles applied from JavaScript can be accessed through scripting.
const setDivWidHeig = document.getElementById('setDivWidHeig');
const divElm = document.getElementById('divElm');
divElm.style.width = '90px';
divElm.style.height = '90px';
setDivWidHeig.addEventListener("click", setDivWidHeigClick);
function setDivWidHeigClick() {
divElm.style.width = parseInt(divElm.style.width) + 10 + 'px';
divElm.style.height = parseInt(divElm.style.height) + 10 + 'px';
divElm.innerHTML = 'width=>' + divElm.style.width + '<br>height=>' + divElm.style.height;
}
setDivWidHeigClick();div {
display: block;
background: #ccc;
word-wrap: break-word;
vertical-align: middle;
text-align: center;
}<div id="divElm"></div>
