Is it feasible to identify the precise x and y coordinates of the character at position 24 (e.g., '-') in this overflowing multi-line text?

Here is a method to determine the text offset position using plain JavaScript without enclosing the text in an element:
var charContainer = document.querySelector('.characters');
var charactersText = charContainer.textContent;
var indexToFind = 25;
var currentOffset;
charContainer.textContent = '';
for (var i = 0; i < charactersText.length; i++) {
var textNode = document.createTextNode(charactersText[i]);
charContainer.appendChild(textNode);
if (i === indexToFind) {
var range = document.createRange();
range.selectNodeContents(textNode);
var clientRects = range.getClientRects();
currentOffset = {
left: clientRects[0].left,
top: clientRects[0].top
};
}
}
alert(JSON.stringify(currentOffset, null, 2));<div class="characters">This is a lengthy multi-line text that exceeds and wraps around</div>I am planning to simplify the process of toggling visibility for 12 different divs when clicking on 12 different buttons.
