Hi is it possible to import a JS function into CSS?

Say I have a JS function

funtion mytitle()
{
return "Something";
}

Is it possible to insert this funtion into CSS' content instead of hard coding it like i did in the snippet? I mean something like

div::after
{ content: mytitle();
}

No, we can't do it but we can accomplish the same result using Lesscss where we can use some built-in function but we can't write our own.

The answer is NO, but there is a work around to achieve this goal. By using attributes to Show ::after content in element.

In below HTML code we are using data-content attribute, where we show are content return value from our jQuery method.

<div data-content=""></div>

In CSS replace content static content: "Something"; value to dynamic attribute value content: attr(data-content);.

div::after {
  content: attr(data-content);
}

Now, just write a simple jQuery method for returning value in data-content attribute.

function mytitle() {
  $('div').attr("data-content", "Something change");
}

mytitle();

All above mentioned changes are already implemented in below code snippet. I hope it'll help you out. Thank You

function mytitle() {
  $('div').attr("data-content", "Something change");
}

mytitle();

div {
  width: 100px;
  height: 50px;
  background-color: blue;
}

div::after {
  content: attr(data-content);
}

<div data-content=""></div>

No, you cannot do this. You must use preprocessors to pass variable/functions to styles.
