Is it possible to set a margin-left using a variable in JavaScript? If so, how can this be accomplished?
The margin left should be equivalent to the clientWidth of the text:
let hoverBubble = document.getElementById(id);
let linkWidth = link.clientWidth + 1;
hoverBubble.style.margin-left = linkWidth + 'px';
To achieve this, simply use camelCase for styling properties.
hoverBubble.style.marginLeft = linkWidth + 'px';
It's important to note that you cannot use a hyphen (minus sign) in the way described in the question.
Using a hyphen can cause the interpreter to misinterpret the assignment operation, leading to a syntax error.
This type of error can be identified and resolved using debugging tools like Chrome Dev Tools (F12 in Chrome, select console) or Firebug (Install Firebug, press F12 on Firefox).
Give this a shot
hoverBubble.style.marginLeft = linkWidth + 'px';
