Is there a way to achieve arithmetic operations in CSS, like calculating
margin-left: -60px + 50% of the width of the parent divThank you,
Mike
Here is a suggestion:
const element = document.getElementById("foobar");
let parentElement = element.parentNode;
while (parentElement && parentElement.nodeName !== "DIV") {
parentElement = parentElement.parentNode;
}
if (parentElement.nodeName === "DIV") {
element.style.marginLeft = -60 + (parseInt(parentElement.style.width) * 0.5) + "px";
} else {
element.style.marginLeft = "-60px";
}
Using JavaScript, it is definitely achievable, however, the code will vary depending on whether you are utilizing vanilla JS or frameworks. Below is an example using jQuery:
$('#element').css('width', (-60+($('#element').parent().width()*.5))+'px');
